摘要
以盆栽短枝型桃品种超红短枝和普通型品种早红珠为试材,研究了水分胁迫对不同生长类型桃树新梢增长率、叶片水分利用效率和羧化效率的影响。结果表明,在水分胁迫条件下,短枝型品种超红短枝的新梢增长率、叶片水分利用效率和羧化效率均显著高于普通型品种早红珠。表明桃短枝型品种对干旱有较高的生理适应性。
Under water stress, the shoot increased rate, the water use efficiency and carboxylation efficiency of two peach varieties were studied under pot cultivation condition. The result showed that super red spur had higher shoot increased rate and higher ability to the water use efficiency and carboxylation efficiency compared with Zaohongzhu. It is indicated that the variety of spur-types peach had higher physiological adaptability under drought condition.
