• The Effect of Low Light Intensity and Temperature on Growth of Schefflera arboricola in Interior Landscapes

  2007

  HortScience · 11 Zitationen · DOI

  Schefflera arboricola was held in light- and temperature-controlled chambers for 6 months under three light intensities of 10 μmol·m –2 ·s –1 , 20 μmol·m –2 ·s –1 , and 80 μmol·m –2 ·s –1 measured as photon flux density ( PFD ). Plants also received three temperature regimes: 15 °C, 20 °C, and 25 °C. Reduced light intensity significantly decreased fresh and dry weight and increased chlorophyll content, but did not affect leaf thickness and palisade and spongy mesophyll parenchyma. High temperatures reduced fresh weight and significantly increased chlorophyll content and leaf thickness. The authors conclude that reduced photosynthetic energy flow at low light intensities (10 μmol·m –2 ·s –1 , 20 μmol·m –2 ·s –1 ) could not be buffered by a down regulation of energy-consuming processes. Therefore the life span and quality of S. arboricola is reduced at such PFD values, especially at higher temperatures. Plants lose their marketability within 6 months.

• Factors Influencing Flowering of Different South African Iridaceae

  2009

  HortScience · 7 Zitationen · DOI

  Because South African Iridaceae have a high potential as new floricultural crops, four spring-flowering geophytic species originating in the Cape Floral Region were investigated. A total of 900 corms for each Freesia laxa , Sparaxis × tricolor , Tritonia deusta , and Tritonia securigera were exported from South Africa during dormancy in 2 subsequent years. Experiments in Berlin, Germany, focused on storage conditions after export and different temperature and light intensity regimes for forcing, in particular their effect on plant habit, inflorescence induction, and flowering success. The results showed that after export, dormancy could be further maintained in storage at temperatures above 20 °C. Temperature was found to be the main criterion to successfully realize flowering after planting; cultivation at 13 °C at night was essential with temperatures of 17 °C and above possible during the day. During summer months, the failure of inflorescences in the terminal bud to develop completely, or the abortion of flower primordia within the corms, was the result of the high temperatures present. Also, low natural light levels during fall months could be linked to flower abortion of the investigated species. However, the results indicate that if forced as pot plants for the European fall and winter, the low temperature requirements of the investigated species during cultivation could represent substantial energy savings for future growers.

• Influence of Sheep’s Wool Vegetation Mats on the Plant Growth of Perennials

  2023

  Horticulturae · 6 Zitationen · DOI

  Vegetation mats for horticulture and landscaping usually consist of coconut fibre and straw. They have hardly any available nutrients and serve only as a carrier material for plant growth. Water capacity is low. By incorporating raw sheep‘s wool, nutrients, such as nitrogen, potassium, and sulphur can positively influence the nutrient content of the carrier material. Water storage and water holding capacity are increased by the wool. In this study, three different thick-layered vegetation mats with different proportions of sheep’s wool and coir fibres were developed for the pre-cultivation of perennials. The focus is on the evaluation of sheep’s wool as a carrier material compared to pure coconut fibre as well as the plant growth of the eight perennial species used (Achillea clypeolata ‘Moonshine’, Achnatherum calamagrostis ‘Algäu’, Anaphalis triplinervis, Aster dumosus ‘Prof. Anton Kippenberg’, Aster dumosus ‘Silberball’, Centranthus ruber ‘Coccineus’, Coreopsis verticillata, Salvia nemorosa ‘Rosakönigin’). The vegetation mats with sheep’s wool (V1–V3) contained 192.6, 154.0, and 283.5 g nitrogen (N)/m2 and the coir mats (V4) contained 7.5 g N/m2. The water content ranged from 16.0 to 22.1 vol% for the sheep’s wool mats and 12.6 vol% for the coir mat at pF1 (is equal to matrix potential at −10 hPa). The air content ranged from 71.9 to 77.0 vol% for the sheep’s wool mat and 79.4 vol% for the coir mat at pF1. On all vegetation mats containing sheep’s wool, the overall impression of the perennials was better than in the control. Especially good were Asters. At the end of the trial, the assessment scores of Asters on the sheep’s wool mats were two scores higher than on the coir mat. Aster dumosus ‘Prof. Anton Kippenberg’ achieved an average plant height between 35.8, 35.8, and 36.5 cm on the sheep’s wool mats and 14.4 cm on the coir mat. Aster dumosus ‘Silberball’ yielded 41.3, 42.3, and 44 cm on the sheep’s wool mats and 26.7 cm on the coir mat. No significant differences regarding plant height between the different variants of sheep’s wool mats emerged. Therefore, these mats can be used as alternative planting concepts for landscaping.

• Acclimatization of Ficus benjamina to temperature and irradiance conditions in indoor landscapes

  2025

  Julius Kühn-Institut · 2 Zitationen · DOI

  The present study examined the effects of temperature and light regimes as a means to acclimatize Ficus benjamina prior to plants being placed in a standard, interior environment. F. benjamina plants were exposed for six months to temperatures of 15, 20 and 25°C combined with photo flux densities (PFD) of 40. 80 and 180 µmol m-2s-1. After treatments, plants were placed in an interior environment at 18 µmol m-2s-1 PFD and 20°C and growth measured. During acclimatization the combination of 15°C and 180 µmol m-2s-1 is critical because leaf number is reduced and the typical leave gloss is lacking. Growth of F. benjamina in interior environment was affected by acclimatization parameters. After six month indoors, growth characteristics were nearly indentical among acclimatization treatments. However, temperature and irradiance during acclimatization inflenced internode lenght growth and carotenoid content plants were placed in an interior environment.

• Influence of Mineral Liquid Fertilization on the Plant Growth of Perennials on Sheep’s Wool–Coir–Vegetation Mats

  2024

  Horticulturae · 2 Zitationen · DOI

  Perennials are usually pre-cultivated on vegetation mats consisting of coconut fiber (coir), which require weather-dependent irrigation and regular fertilization with fast-acting fertilizer to achieve a saleable condition as quickly as possible. In the pre-cultivation of sheep’s wool–coir–vegetation mats, nitrogen (N) is already sufficiently contained in the vegetation mats due to the natural nitrogen content of the sheep’s wool fibers, so that additional liquid fertilization during pre-cultivation can be dispensed with if necessary. In this study, sheep’s wool–coir–vegetation mats of 4.5 kg/m2 were pre-cultivated with 16 perennial plants (8 species) in 2018. Variant 1 (V1) received regular fertilization with mineral liquid fertilizer (total 8.7 g N/m2) during pre-cultivation. Variant 2 (V2) was not fertilized during pre-cultivation. In spring 2019, all pre-cultivated vegetation mats were lifted and laid on an area prepared with topsoil. No additional fertilization was applied after laying. The overall impression, plant height, number of flowering perennials, and plant coverage were examined in the 2018 and 2019 growing seasons, with only minor differences observed between V1 and V2. The number of flowers, biomass, and nitrogen content were determined for the two aster species used. There were differences between V1 and V2 in 2018, but not in 2019. The coverage of perennials of 50%, which is the prerequisite for the saleability of the vegetation mats, was already achieved on both V1 and V2 after 4 months of pre-cultivation. The overall impression of the perennials on both V1 and V2 also did not differ during pre-cultivation nor in the following year. Therefore, liquid fertilization is not necessary during the pre-cultivation of perennials on sheep’s wool–coir–vegetation mats.

• Can Green Plants Mitigate Ammonia Concentration in Piglet Barns?

  2021

  Atmosphere · 2 Zitationen · DOI

  For animal welfare and for farmers’ health, the concentration of ammonia (NH3) in animal houses should be as low as possible. Plants can remove various atmospheric contaminants through the leaf stomata. This study examined the effect of ornamental plants installed inside a piglet barn on the NH3 concentration in the air. Gas measurements of the air in the ‘greened’ compartment (P) and a control compartment (CTR) took place over two measuring periods (summer–autumn and winter). Differences between the NH3 emissions were calculated based on the ventilation rates according to the CO2 balance. Fairly low mean NH3 concentrations between 2 and 4 ppm were measured. The NH3 emissions were about 20% lower (p &lt; 0.01) in P than in CTR, in summer–autumn and in winter period.

• Alternative Wachstumsregulierung von Pflanzen mittels gesteuerter Vibrationstechnik als Ersatz chemischer Hemmstoffe

  2016

  Organic Eprints (International Centre for Research in Organic Food Systems, and Research Institute of Organic Agriculture) · 2 Zitationen

  Steigende Umweltbelastungen durch Pestizide, in diesem Falle durch chemische Wachstumsregulatoren, erfordern Forschungen zur alternativen Wachstumsregulierung. Der Aktionsplan zur nachhaltigen Anwendung von Pflanzenschutzmitteln des BMEL unterstreicht dieses Absicht. Im durchgeführten Projekt soll eine Wachstumsregulierung (hauptsächlich die Hemmung des Längenwachstums) durch definierte mechanische Reize (Seismomorphogenese) mittels Vibrationen realisiert werden, um einen Verzicht auf synthetische Wuchshemmstoffe möglich zu machen. Die Entwicklung eines anwendertauglichen Vibrationstisches erfolgte zunächst in der Forschungseinrichtung. Anschließend wurden in zwei zertifizierten Bio-Gartenbaubetrieben entsprechende Tische auf ihre Praxiseignung getestet. Zwischenauswertungen der ersten Ergebnisse führten zu einer Neuentwicklung von gut geeigneten, praxistauglichen und auch größeren (bis 9 m langen) Vibrations-Rolltischen. Eine wuchshemmende Wirkung an zahlreichen ausgewählten Zierpflanzen (u.a. Pelargonium, Petunia und Euphorbia pulcherrima) ist nachweisbar. Auch verschiedene Topfkräuter konnten erfolgreich im Wachstum gehemmt werden. Sehr wichtig ist es, um Blattschäden zu vermeiden, bei empfindlichen Arten (z.B. Pflanzen mit weichen Blättern) mit niedrigen Frequenzen (15 bis 18 Hz) und kürzeren Intervallen (z.B. 2x 2,5 min/h) zu arbeiten.&#13;\nPrinzipiell kann jeder Gartenbaubetrieb, der seine Pflanzen auf Tischsystemen kultiviert, mit Vibrationstischen ausgestattet werden. Die enge und konstruktive Zusammenarbeit im Netzwerk „Bio-Zierpflanzen“ ist als besonders positiv hervorzuheben und hat wesentlich mit zum Gelingen des Projektes beigetragen. Wirtschaftlichkeitsberechnungen vervollständigen die erfolgreiche Projekt-Umsetzung. Die tatsächlichen ökonomischen Erfolgsaussichten lassen sich jedoch zum jetzigen Zeitpunkt noch nicht vollständig benennen.&#13;\nAllgemein ist festzustellen, dass durch dieses Projekt die Wichtigkeit der Verminderung synthetischer Wachstumsregulatoren im Zierpflanzenbau und die Reduzierung von Pestiziden im gesamten Gartenbau mehr in den Mittelpunkt des Interesses gerückt werden konnte. Dieses Projekt leistet somit einen nachhaltigen Beitrag auf dem Weg zur Erzeugung rückstandsfreier pflanzlicher Produkte.

• WATER FLOW IN CUT ROSE PEDUNCLES â DESTRUCTIVE AND NON DESTRUCTIVE MEASUREMENT METHODS

  2010

  Acta Horticulturae · 2 Zitationen · DOI

  The difference in vase life and bent-neck resistances of the three cut rose cultivars 'Akito', 'Milva' and 'Red Giant' was evaluated by destructively and non-destructively investigating the water status of their peduncles. Results of destructive measurements of the actual hydraulic conductivity (K h ), which represents the actual water transport capacity, showed that samples of 'Milva' and 'Red Giant' had higher K h than those of 'Akito'. In situ water flow velocity and water distribution in peduncles were analyzed by cold neutron radiography (CNR) and tomography (CNCT). The water flow velocity in peduncles of 'Milva' was highest that of 'Akito' was intermediate, while 'Red Giant' roses showed the least flow velocity. These results seem to be inversely to those obtained from the K h measurement. Water losses of the peduncles during drought stress were estimated from the comparison of water distribution images obtained by CNCT. After drought stress the water losses of 'Akito' peduncles were largest, water losses of 'Milva' peduncles were similar to those of 'Akito'. Hence, 'Red Giant' roses were able to retain tissue water in spite of the given drought stress.

• South African geophytes: comparison of temperature and light intensity requirements for container production under Central European conditions

  2010

  European Journal of Horticultural Science · 2 Zitationen · DOI

  Summary South African Iridaceae contain many genera with a high potential for new floricultural crops. This potential was accessed in four geophytic species of the genera Freesia , Sparaxis and Tritonia , native to the Cape Floral Region which are winter growing and spring flowering in the Southern Hemisphere. If forced as pot plants for the European autumn and winter months, their low temperature requirements during cultivation could represent substantial energy savings. The aim of this study was to evaluate and compare temperature and light intensity requirements of the chosen species when subjected to selected forcing regimes for pot plant production under Central European conditions. The trials focused on the following aspects: export during corm dormancy, storage conditions after export, forcing experiments at different periods of the year in Berlin and general cultivation requirements of the different species/hybrid. These were compared to Freesia × hybrida , a well known geophytic ornamental crop originating from South Africa, although mostly grown as a cut flower. Results were obtained by regular monitoring of inflorescence initiation in the shoot apex meristem as well as of the plant development. The export of dormant corms from South Africa proved to be uncomplicated as their dormancy could be further maintained by subsequent storage at temperatures above 20°C. Temperature during forcing was found to be the main factor affecting flowering after planting. The species varied in their sensitivity to growth temperatures above 20°C, but generally cultivation at 13°C at night was essential, with temperatures of 17°C and above possible during the day. During the Central European summer months, inflorescences in the terminal bud failed to completely develop or flower primordia were aborted within the corm due to the high growth temperatures. Also, low natural light levels during European autumn months increased flower abortion of the investigated species. A reduction in plant height and enhanced flowering could be achieved for some species by specific storage regimes.

• Comparative study of perennial mixtures on sheep's wool-coir-vegetation mats versus Sedum in carbon sequestration and cooling effect of green roofs

  2025

  Building and Environment · 1 Zitationen · DOI

  • Pre-cultivated vegetation mats with sheep’s wool and coir (SW-C-VMs) are sustainable. • Perennial mixture on SW-C-VMs is more ecologically valuable than with Sedum species. • Green roofs with perennial mixture have a 7 times higher carbon sequestration than with Sedum species. • Temperatures on perennial mixture are lower in summer than on Sedum . Urban areas characterised by high population density often lack sufficient green spaces, which diminishes their ecological and climatic benefits. Green roofs as additional ecosystems can make a positive contribution to the urban climate. In Germany, extensive green roofs, which are usually characterised by Sedum vegetation, are predominantly used. Sedum is suitable for sunny and semi-shady locations, requires low-maintenance and needs few nutrients and water. However, the urban climatic effect of Sedum is low. In this study, sheep's wool-coir-vegetation mats (SW-C-VMs) pre-cultivated with a perennial mixture was compared to a conventional Sedum vegetation using the example of Berlin (Germany). The perennial mixture showed a 7 times higher carbon sequestration than the Sedum vegetation. Due to the good water storage and fertilising effect of the sheep's wool, the perennial mixture did not need to be irrigated or fertilised and was self-sustaining on the green roof. The temperatures on the surface of SW-C-VMs with perennial mixture and at a depth of 0.1 m in the substrate were significantly lower and more balanced in summer than on the substrate surface and at a depth of 0.1 m in the substrate of the Sedum vegetation. On days with high air temperatures, the maximum temperatures on the SW-C-VMs with perennial mixture were up to 17.0 K lower than on the substrate surface of Sedum . In future, SW-C-VMs with a perennial mixture are recommended for semi-shaded green roofs and are preferable to Sedum . A green roof with pre-cultivated SW-C-VMs with a perennial mixture has a higher ecological value than a green roof with Sedum species.

• Growth Regulation of New Clones of Rotheca myricoides 'Uganden- sis' (syn. Clerodendrum ugandense)

  2007

  SHILAP Revista de lepidopterología · 1 Zitationen · DOI

  The occurrence of position effects, i.e. topophysis, was tested for two new clones (29 and 112) of Rotheca myricoides (Hochst.) Steane & Mabb. ‘Ugandensis’ (syn. Clerodendrum ugandense Prain). The position from which cuttings are taken from of the mother plant can affect the later vegetative and generative development of the plants, e.g. partly reduce their extensive longitudinal growth. Three different kinds of cuttings were used during propagation in two sets of experiments: tip cuttings of vegetative branches, stem cuttings of vegetative branches and stem cuttings of generative branches. Their height, branching and flowering development was assessed in periodic intervals over a period of four months. Compared to 112, clone 29 displayed a significantly reduced longitudinal growth and a significantly better rate of branching was displayed. Furthermore, the results for the vegetative tip cuttings of both clones showed a significant decrease in height (6–10 cm) compared to the stem cuttings from vegetative branches combined with an increase in branching (1–2.5 branches) compared to both other types of cuttings. Apart from choosing the appropriate clone, using vegetative tip cuttings can therefore be a partly effective method to reduce the extensive height and improve the branching during commercial production of Rotheca myricoides ‘Ugandensis’. With regard to flowering, no significant differences between the two clones and the three types of cuttings were found in the statistical analysis.

• Steril-Kulturverfahren zum Aufbau gesunder Mutterpflanzenbestände für den ökologischen Zierpflanzenbau

  2020

  Organic Eprints (International Centre for Research in Organic Food Systems, and Research Institute of Organic Agriculture)

  Das Forschungsvorhaben „BioVitro“ bestand zunächst aus den Projekt-Teilen: Entwicklung einer In-vitro-Kulturstrecke zur Vorkultur von gesundem Elite-Material, der Überführung sowie Gewächshausversuchen zu Mutterpflanzenaufbau und Stecklingsgewinnung unter ökologischen Produktionsbedingungen. Gearbeitet wurde mit drei ausgewählten bedeutenden Zierpflanzengattungen (Chrysanthemum, Pelargonium und Petunia)Auf der In-vitro-Kulturstrecke wurden erstmals überhaupt die Vorgaben der EU-Öko-VO berücksichtigt (Pflanzenernährung und Pflanzenschutz). Als Betriebsmittel kamen ausschließlich FiBL-gelistete Düngemittel sowie „Produkte und Nebenprodukte pflanzlichen Ursprungs“ zum Einsatz. Für den ökologischen In-vitro-Kultur-Ansatz wird der Begriff „BioVitro“ gesetzt.&#13;\nNeben dem Verzicht auf mineralische Nährsalze inkludiert die Bezeichnung BioVitro eine Abkehr von der Verwendung synthetischer Wachstumsregulatoren in der pflanzlichen In-vitro-Kultur. Auch die Kultur-Etablierung muss auf Basis zugelassener Betriebsmittel erfolgen. Ethanol, Chlor oder Quecksilber sind in der Anwendung an der Pflanze untersagt.&#13;\nFür Chrysanthemum konnte ein praxisgerechter BioVitro-Zyklus (Etablierung, Erhaltung/Vermehrung, Überführung) demonstriert werden. Nach organischer Vorkultur erreichen die beobachteten Wuchsleistungen in vitro das Niveau konventioneller Verfahren. Die Kultur-Etablierung erfolgt über das direkte Aufsetzen von Sprossspitzen (&lt; 2 mm). Pelargonien entwickeln sich in vitro nur langsam. Unter BioVitro-Bedingungen können bislang nur Seitensprosse für einen Bestandsaufbau verwendet werden. Die Kultur-Etablierung über Sprossspitzen direkt aus dem Gewächshaus gelingt noch nicht. Für Petunia konnte ein BioVitro-Kulturmedium entwickelt werden, dass sich in der Zusammensetzung vom Substrat für Chrysanthemum deutlich unterscheidet. Auf dem Medium wurden Kallus- und Adventivsprossbildungen beobachtet. Die Kulturetablierung unter BioVitro-Vorgaben auf ein ökologisches Medium steht aus. Überführungen von Chrysanthemum und Pelargonium (Petunia ohne Wiederholung) aus BioVitro auf Bio-Substrate unter ökologischen Produktionsbedingungen im Gewächshaus gelangen sehr gut. Pflanzen aus BioVitro wurden als überaus robust wahrgenommen, ein Zusammenhang mit der organisch geprägten Vorkultur wird vermutet. Von Chrysanthemum (zwei Sorten) und Pelargonium (eine Sorte) wurden erstmals Bio-Mutterpflanzen-Bestände aus BioVitro-Vorkultur aufgebaut und beerntet. Bei Pelargonium wurden dazu zwei Pflanzen-Generationen herangezogen. Das Bewurzelungsvermögen der Bio-Stecklinge ist gut. Unter den Bedingungen des Forschungsbetriebes sowie bei Nutzung der baulichen Gegebenheiten am Standort Forschungsgewächshaus der HU-Berlin in Berlin-Dahlem, konnten phytopathologische Vorgaben in der Mutterpflanzenkultur nicht erfüllt werden. Schädlingsbefall (Thripse) wurde beobachtet und mit Nützlingen erfolgreich bekämpft. Die Marktfähigkeit entsprechender Erntechargen war nicht in jedem Fall gegeben. Im Zuge der erfolgreichen Arbeiten mit Chrysanthemum wurde im Projektverlauf ein weiterer Projektteil mit öffentlichkeitswirksamen Außendarstellungen notwendig und realisiert. Mit der Präsentation eines „Minimal-Labors“ auf der IPM (Essen, 2019) sowie auf der Bundesgartenschau (Heilbronn, 2019) konnte der völlig neue bio-basierte Kulturansatz der Fachwelt wie auch interessierten Konsumenten nahegebracht werden. Produkt- und Video-Präsentationen zu BioVitro auf zahlreichen Veranstaltungen des Ökologischen Zierpflanzenbaus leisteten notwendige Aufklärungsarbeiten zur Thematik. Weiterführende Forschungsfragen wurden formuliert.
