| 摘 要： | 采用温室模拟干旱胁迫-复水法,对收集自6个国家的10种偃麦草属植物的种间苗期抗旱性进行综合评价,分别于干旱胁迫开始前(CK),连续干旱胁迫7,14,21,28,35 d,以及复水7d后,对其叶片相对含水量(RWC)、相对电导率(REC)、脯氨酸含量(Pro)、丙二醛含量(MDA)、可溶性糖含量(SSC)5个抗旱生理指标...

| Abstract: | The drought resistance of 10 species of Elytrigia,collected from six countries,was identified and evaluated using simulated drought stress and rewatering in a green house at the seedling stage.The relative water content of leaves(RWC),relative electrical conductivity rate(REC),free proline accumulation(Pro),contents of malondialdehyde(MDA) and the soluble sugar content(SSC) were measured at 0(CK),7,14,21,28,and 35 days of drought stress and 7 days after rewatering.Their average survival rates(ASR) after 35 ... |
