【Abstract】 Effect of mild water stress on the amino acid changes in spur and leaf in relation to flower bud formation in Mei flower cv. Jiangmei and Yudie was studied. During flower bud formation, the total content of amino acids in spur decreased, and arginine increased. The content of amino acids in leaf changed slightly. Free amino acid concentration in leaf of plant with mild water stress (42-47% of field capacity) was twice as much as that of the control plants (70-85% of field capacity). Intensity of water stress was suitable at -4--8 bars and extreme water stress injuried the plants.更多还原
