Effects of nitrogen and phosphate fertilization on leaf nutrient content, photosynthesis, and growth of the novel bioenergy crop Fallopia sachalinensis cv. ‘Igniscum Candy‘

Laurie Anne Koning, Maik Veste, Dirk Freese & Stefan Lebzien
The aim of the study was to determine the effects of nitrogen and phosphate fertilization on the growth performance of the novel bioenergy crop Fallopia sachalliensis cv. ‘Igniscum Candy’ (Polygonaceae). In a controlled pot experiment various nitrogen (0, 50, 150, 300 kg N ha-1) and phosphate (20, 40, 80 kg P ha-1) fertilizer amounts were applied to measure the effect on the biomass, height, leaf area and nitrogen and phosphate use efficiency. Furthermore, ecophysiological processes...

Sodium accumulation contributes to salt stress tolerance in lettuce cultivars

Csaba Bartha, Laszlo Fodorpataki, Maria Del Carmen Martinez-Ballesta, Octavian Popescu & Micaela Carvajal
Increasing soil salinity of irrigated agricultural areas represents a major environmental stress factor that impairs the production of many salt-sensitive crop plants. Different lettuce cultivars were studied for identification of more tolerant ones, based on physiological properties. Five selected lettuce cultivars were grown hydroponically, salt stress was induced by 50 mM and 100 mM of NaCl. The cultivars exhibited differential reduction in shoot fresh weight. The highest sodium and free proline accumulation in the shoot...

Ethnobotanical review of wild edible plants used in the Czech Republic

Katerina Simkova & Zbynek Polesny
This paper is the literature survey of wild food plants used within the present borders of the Czech Republic. Thirty-seven freely available publications documenting the culinary use of wild plants were examined. The use of 175 vascular plant species (approximately 5% of native and naturalized flora of the Czech Republic), 3 lichens and 1 bryophyte has been reported. For each species listed, plant parts used, use category and mode of consumption are given. Rosaceae, Asteraceae...

Evaluation of substitutes for rock wool as growing substrate for hydroponic tomato production

Dennis Dannehl, Johanna Suhl, Christian Ulrichs & Uwe Schmidt
To reduce the rock wool waste, the present study is focused on the evaluation of sheep wool, Sphagnum and hemp slabs, which may be used as replacement for rock wool as growing substrate for hydroponic tomato production. As such, physical and chemical properties of substrates, the plant growth, yield, fruit characteristics, as well as primary and secondary metabolites of tomatoes were considered. The marketable fruit yield of plants grown in Sphagnum slabs (12.8 kg plant-1)...

Photosynthetic capacity of canola (Brassica napus L.) plants as affected by glycinebetaine under the salt stress

Ayesha Khalid, Habib-Ur-Rehman Athar, Zafar Ullah Zafar, Ahmad Akram, Kausar Hussain, Hamid Manzoor, Fahad Al-Qurainy & Muhammad Ashraf Ashraf
Salinity causes reduction in growth and severe losses of crop productivity by affecting various biochemical and physiological processes including photosynthesis. Plants sense and adapt to salt stress by modulating different physiological processes including accumulation of osmoprotectants. Glycinebetaine (GB) is an important osmoprotectant and found to have ameliorative effects on the growth of plants by altering ion homeostasis, photosynthetic and antioxidant capacity. In this study, it was attempted to reveal how GB improves photosynthetic activity and...

Quality and fruit colour change in Verna lemon

Ignacio Porras, Jose Manuel Brotons, Agustín Conesa, Ramón Castañer, Olaya Pérez-Tornero & Francisco Javier Manera
While most of lemon cultivars in the northern hemisphere are harvested in autumn-winter, Verna, an autochthonous Spanish cultivar, is harvested later (February to August), supplying the European market when lemons are in short supply, a market that is also served by imports from the southern hemisphere, mainly Argentina and South Africa. The aim of this study was to determine the temperature at which degreening begins naturally in Verna lemon, noting the evolution of colorimetric parameter...

Reduction of apple vegetative shoot growth cv. Starcrimson Delicious/MM 111 with prohexadione calcium application does not decrease fruit quality

Melike Çetinbaş, Sinan Butar, Adem Atasay, Mesut İşçi & Hakkı Koçal
Prohexadione-calcium % 10 (Pro-Ca) has been shown to effectively reduce the vigor of apple trees. However, it is important that the reduction of vegetative shoot growth does not decrease yield and fruit quality. The primary objective of this study was to determine the response of Starcrimson Delicious/MM111 apple trees to foliar Pro-Ca application and its effect on vegetative growth and fruit quality. For this reason, trees were sprayed twice within a three weeks interval with...
