Anatomical root variations in response to water deficit: wild and domesticated common bean (Phaseolus vulgaris L).
Root anatomical responses to water deficit are diverse and regulation of water uptake strongly depends on plant anatomy. The ancestors of common bean (Phaseolus vulgaris L.) cultivars are the wild common beans. Because wild beans adapt and survive well in the natural environment, it is hypothesized that wild common bean roots are less affected than those of domesticated beans at low substrate w...
متن کاملGrowth, nitrogen fixation and ammonium assimilation in common bean (Phaseolus vulgaris): effect of phosphorus
The impact of phosphorous nutrition on plant growth, symbiotic N2 fixation, ammonium assimilation, carbohydrate and aminoacid accumulation, as well as on nitrogen, phosphorus and ATP content in tissues in common bean (Phaseolus vulgaris) plants was investigated. Plants inoculated with Rhizobium tropici CIAT899 were grown in Leonard jars under controlled conditions, with P-deficient (0 and 0.1mM...
متن کاملEffect of water supply on seed quality development in common bean (Phaseolus vulgaris var.)
In order to determine the best developmental stage of three common bean cultivars (Talash, COS16 and Khomain) at which maximum seed quality is attained under different irrigation regimes (I1-irrigation after 60 mm, I2-irrigation after 80 mm and I3-irrigation after 100 mm evaporation from class A pan), a split plot experiment (using R.C.B. design) with 3 replications was conducte...
متن کاملAmmonium assimilation and ureide metabolism in common bean (Phaseolus vulgaris) nodules under salt stress
The effect of salinity on ammonium-assimilation enzymes, as well as on the enzymes of purine catabolism, was studied in root nodules of common bean plants grown in an environmentally controlled chamber. Salt treatments (0, 25, 50 and 100 mM) were applied during the vegetative period, when the symbiosis was well established. Four harvests were made, two during the vegetative and two during the r...
