Effects of Drought Stress on Physiological Characteristics and Endogenous Hormone Contents in Leaves of Soybean Seedlings
Background: Two soybean cultivars with contrasting drought tolerance-Heinong 44 (HN-44, tolerant) and Heinong 65 (HN-65, sensitive)-were used in a pot-culture experiment to investigate the physiological mechanisms underlying their differential responses to water deficit. Methods: Water deficit was imposed by supplement...
