| 摘 要： | 以盆栽大叶黄杨为试材,研究了大叶黄杨生长与生理指标对不同程度土壤水分胁迫的响应.结果表明:土壤水分胁迫对生长指标(苗重、苗高和地径)有明显的影响,变化表现出一致的规律性,即随胁迫程度加剧均呈现出下降趋势.干旱胁迫下生理指标的变化表现出差异性:束缚水/自由水的比值随胁迫程度加强而增大;水分饱和亏缺变化和丙二醛活性在轻、中...

| Abstract: | With potted Euonymus japonicus as material,the growth and physiological response of Euonymus japonicus to soil gradient moisture stress was studied.The results show that there are significant effects on growth indicators such as weight,high and ground diameter,which are congruously declined along with the aggravation of drought stress under different soil moisture stress.While the physiology indexes changes show in the following aspects' differences.The ratio of bound water to free water is getting larger a... |
