摘要
采用盆栽方法,以鸢尾属的鸢尾、马蔺、黄菖蒲、花菖蒲和溪荪为试验材料,研究了在干旱胁迫下5种植物的形态和部分生理指标的变化。结果表明:在干旱胁迫下,5种植物叶片的相对含水量下降;相对电导率、脯氨酸含量上升,可溶性蛋白含量的变化不完全相同。5种植物的抗旱性强弱顺序为:鸢尾>马蔺>黄菖蒲>花菖蒲>溪荪。
The physiological factors of five Iris species： I. tectorum, I. lactea var. chinensis, I. pseudacoru, I. ensata var- hortensis, I. sanguinea were studid based on pot experiment under drought stress. It was showed that under drought stress the relative water content was decreased; relative electric conductivityand free proline content were increased; Changes of soluble protein were different. And the drought resistance of Iris species from strongest to the weakest were as follow. I. tectorum , I. lactea vat. chinensi , I. pseudacoru , I. ensata vat. hortensis , I. sanguinea.
