تاثیر قطع آبیاری در زمان رشد زایشی گیاه مادری بر خصوصیات کیفی بذر لوبیا (Phaseolus vulgaris)

Drought stress is one of the most important factors in arid and semiarid regions that limits crop production and seed quality. In order to study the effect of water termination in different reproductive stages (flowering and podding) of two cultivars of common bean (Khomein and Goli) a randomized split plot experiment was conducted in agricultural lands of Shiraz University, Bajgah, Iran. The results showed that seeds of maternal plants that experienced water deficiency had significantly lower seed viability and vigour in both cultivars. It was concluded that the two examined cultivars in this study are sensitive to water stress during reproductive stage and should be irrigated sufficiently to produce seeds with high quality.
