a growth chamber study was carried out to evaluate the allelopahtic effects of shoot and root water extract of hoary cress (cardaria draba) on seed germination and seedling characteristic of sorghum (sorghum bicolor). the study was conducted based on completely randomized design with four replications in research laboratory of faculty of agriculture, university of birjand in 2008. treatments we...

investigation of various irrigation methods and intercropping are effective strategies for increasing water use efficiency and improve crop production. a field experiment conducted to study the effects of alternate furrow irrigation on quantitative and qualitative characteristics of forage corn with annual alfalfa cropping under its canopy in ilam climate conditions. experiment carried out as a...

This article reports the ginger protease extraction and purification methods from fresh ginger rhizome. As to ginger protease extraction, we adapt the steps of organic solvent dissolving, ammonium sulfate depositing and freeze-drying, and this method can attain crude enzyme powder 0.6% weight of fresh ginger rhizome. The purification part in this study includes two steps: cellulose ion exchange...

A method has been developed for culturing detached nitrogen-fixing root nodules of lupin (Lupinus angustifolius L.) on a simple nutrient medium. Under the best conditions devised, the acetylene reduction activity of mature detached nodules was maintained at 10 to 25 nmoles of ethylene hr(-1) mg(-1) fresh weight for 3 days. Under the same culture conditions, immature nodules increased their acet...

Free methionine levels in rin and normal tomato fruits were determined microbiologically. Similar levels (1750 mug/100 g fresh weight) for mature green fruits of both rin and a normal isogenic line suggest that the lack of ripening of rin fruits is not due to low methionine levels. Methionine levels of mature green rin and normal fruits were 1750 mug/ 100 g fresh weight. Normal fruits ripened e...

Hairy root cultures of Brugmansia suaveolens were set up by infection of root tips with Agrobacterium rhizogenes. The successful transformation was confirmed by analysing rolC and virC genes using polymerase chain reaction (PCR). Hairy root cultures were employed to study the formation of tropane alkaloids, such as hyoscyamine. The transformed cultures were incubated with potential elicitors, s...

Fernández-León M.A., Lozano M., González D., Ayuso M.C., Fernández-León M.F. (2014): Bioactive compounds content and total antioxidant activity of two savoy cabbages. Czech J. Food Sci., 32: 549–554. The bioactive compounds, as well as the in vitro antioxidant activity of two Savoy cabbage cultivars, Dama and Leticia, grown in west of Spain under similar conditions were identified, quantified a...

A field experiment to study the influence of fertigation of N, P and K fertilizers on biometric characters of cocoa (Theobroma cacao L.) was conducted at the Department of Spices and Plantation Crops, Horticultural College and Research Institute, Tamil Nadu Agricultural University, Coimbatore during January 2010 to December 2011. The experiment was laid out with thirteen treatments replicated t...

Leaf area information is required in various horticultural and physiological studies and it will be more useful if done via non-destructive methods. The objective of this study was to establish equations to estimate leaf area (LA) using length (L), width (W), fresh weight (FW), dry weight (DW), length × length (L2), width × width (W2), length × width (L×W), length + width (L+W), fresh weight × ...
