In order to investigate water deficit stress on 24 of soybean (Glycine Max. L) cultivars and lines in temperate climate, an experiment was conducted in Iran Seed and Plant Improvement Institute. Stress levels were irrigation after evaporation of 50, 100, 150 mm water from pan, class A. Randomized Completely Block Design was arranged for each stress levels. Some traits such as, node number, plan...

We evaluated selected soybean, Glycine max (L.) Merr., genotypes during their reproductive stages for resistance to the soybean aphid, Aphis glycines Matsumura (Hemiptera: Aphididae), under greenhouse conditions and documented the categories of aphid-resistant soybean. Two screening studies were performed to assess the level of resistance to the soybean aphid on six soybean genotypes during the...

Production of high quality seeds in African leafy vegetables has not been practiced due to varying reasons including incorrect harvesting stages and fertilizer rates. Jute mallow (Corchorus olitorius L.) pods do not ripen simultaneously and fruits left to dry on mother plant long before harvesting, which face seed quality deterioration. Timely seed harvesting ensures maximum seed quality attrib...

The effects of water stress on morphometric characteristics of wild radish seeds as well as the expression of its seed dormancy were investigated in a pot trial at Roseworthy, South Australia in 2005. This experiment was carried out in a completely randomised design with five water regimes (control, S4, S5, S6 and S8) and four replicates. The water stress was exerted by withholding irrigation a...

BACKGROUND AND AIMS Coordination of sugar transport and metabolism between developing seeds and their enclosing fruit tissues is little understood. In this study the physiological mechanism is examined using two genotypes of asparagus bean (Vigna unguiculata ssp. sesquipedialis) differing in pod wall and seed growth rates. Pod growth dominates over seed growth in genotype 'Zhijiang 121' but not...

Drought is one of the limiting factor in common bean, development of common bean varieties that adapted to drought situations is the main focus for improving food crops. In this study, 25 genotypes of common beans (Phaseolus vulgaris L.) were grown under drought stress and non-stress conditions. The field work was conducted at Melkassa Agricultural Research Center during the off-season that lai...

jimsonweed (datura stramonium l.) is an important weed in bean fields in iran. in order to investigate the effect of density and relative time of emergence of jimsonweed on yield and yield components of chitti bean, a field study based on factorial experiment was conducted at farm bean research national station in khomein in 2006. treatments were chosen to provide four different weed densities ...
