pinto bean is a susceptible plant to drought stress. however, there is genotype variation for this trait in this plant. in order to investigate the effects of drought stress on physiological traits and grain yield of pinto bean genotypes cultivated in zanjan province, an experiment was conducted as spilt plot based on a completely randomized block design with four replications at zanjan univers...

seed loss at harvesting time is one of the factors reducing seed yield in at farms. this study was carried out within a research farm in karaj to evaluate and select a proper pinto bean line for mechanized harvesting at two moisture contents during harvesting and their effect on seed yield and yield loss among three lines of pinto bean. the experiment was split-plot based on randomized complete...

in order to study the biological fixation efficiency of different strains of symbiosis bacteria in three varieties of common bean (phaseolus vulgaris l.) a factorial experiment based on randomized complete block design was conducted in zanjan province during 2006 and 2007. in this investigation three strains of rizobium including: rb117 (extracted from the zanjan soils), rb123 (extracted from t...

We studied the effects of soil matric potential and salinity on the water use (WU), water use efficiency (WUE) and yield response factor (Ky), for wheat (Triticum aestivum cv. Mahdavi) and bean (Phaseoulus vulgaris cv. COS16) in sandy loam and clay loam soils under greenhouse conditions. Results showed that aeration porosity is the predominant factor controlling WU, WUE, Ky and shoot biomass (B...

Conditional cdc1(Ts) mutants of S. cerevisiae arrest with a phenotype similar to that exhibited by Mn(2+)-depleted cells. Sequence similarity between Cdc1p and a class of Mn(2+)-dependent phosphoesterases, as well as the observation that conditional cdc1(Ts) growth can be ameliorated by Mn(2+) supplement, suggests that Cdc1p activity is sensitive to intracellular Mn(2+) levels. This article ide...
