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 ...
