| 摘 要： | 在日光温室PEG-6000模拟干旱胁迫条件下,通过测定6个多年生黑麦草(Lolium perenne L.)品种的相对含水量(RWS)、细胞质外渗率(RPP)、游离脯氨酸(Pro)、叶绿素(Chl)、超氧化物歧化酶(SOD)活性、过氧化氢酶(CAT)活性和丙二醛(MDA)含量等7个理化指标,利用主成分及隶属函数分析法对其抗旱性进行综合评价。结果表明:7个差异显著的抗旱指标应用主成分分析归纳成3个主成分,通过综合隶属函数值评定的抗旱性强弱顺序为:欧必克>多福>努依>卓越>凤凰>雅晴。

| Abstract: | The drought resistance of six Lolium perenne fodder varieties at the seedling stage was studied by using PEG-6000 solution to simulate drought stress in the green house.The physiological and biochemical indexes such as relative water content(RWC),exosmosis rate of cytoplasm(RPP),proline content(Pro),chlorophyll contents(Chl),content of malondialdehyde(MDA),activities of superoxide dismutase(SOD)and CAT were measured.Drought resistance was evaluated by principal components analysis and subordinate function analysis.Results show that the seven significantly different drought-resistance indexes could be classified into 3 component parts.The capacity of drought resistance of the six Lolium perenne fodder varieties is gauged as follows:Oupec>Tove>Nul>Eminent>Polim>Yatsyn. |
