yield in most crops is resulted from a number of physiological processes which occurred during plant growth and development. these processes are realized at morphological, pheonological and physiological levels and often are controllded by many genes. in order to determine the effective of physiological traits onseed yield of soybean (glycine max l.) cultivars and their relationship with yield ...

drought is one of the most important factors limiting growth and yield in many parts of the world. in order to evaluate the effects of drought stress on some morphological and physiological traits of two cultivars of bean, two red beans (derakhshan and goli) in four drought treatments including 25%, 50%, 75%, control 100% field capacity were studied in a factorial experiment based on complete r...
