| 摘 要： | 以＂晋燕14号＂裸燕麦为研究对象,进行人工盆栽,在第四子叶期进行生长指标测量,对其苗期叶片进行抗旱性研究。测定裸燕麦幼苗叶片在干旱胁迫下叶绿素含量、电导率、游离脯氨酸含量、株高、干重以及鲜重的变化情况。结果表明,与对照组相比,在干旱胁迫条件下,裸燕麦的电导率逐渐上升,叶绿素a、叶绿素b和叶绿素a＋b含量具有上升的趋势,游离的脯氨酸含量也逐渐上升,但其株高和鲜重以及干重却呈下降趋势。因此对叶片的叶绿素含量、电导率、游离脯氨酸的测定可以作为裸燕麦抗旱鉴定的生理生化指标。

| Abstract: | The ＂Jinyan 14＂ avena nuda L.are planted in pots.In the fourth cotyledon stage,the growth index and drought resistance of leaves are measured.The items include chlorophyll content,conductivity,free prolines content,plant height,dry weight,and weight changes.Results show that under drought stress,compared with the control group,the conductivity increases gradually,the chlorophyll a,chlorophyll b,chlorophyll a＋b and free prolines content imcrease too.But the height and weight decrease.Thus,the items measured can be the physiological and biochemical indicators of drought resistance. |
