高温胁迫下蝴蝶豆的生理响应和耐热性评价

摘要

以自然高温胁迫下的11份蝴蝶豆为材料,研究叶片厚度、叶绿素值、叶片含水量、电导率值和丙二醛(MDA)含量等外观和生理指标与对照的差异,隶属函数分析结果表明:在高温胁迫下,材料C4、C6、C11的生长表现较好,在叶绿素含量、质膜透性、叶片含水量、MDA含量中的综合反应均较好,相比其它8个材料具有较好的相对耐高温特性,C1和C5的综合反应较弱,为热敏材料.%In this paper,the natural heat treatment on 11 kinds of C.pubescens materials,the research on difference of appearance and physiological indexes of leaf thickness,chlorophyll value,leaf water content,electrical conductivity value and MDA content with the control were carried,through the membership function analysis showed that:material C4 and C6 and C11 plant growth performance were better,in the chlorophyll content and membrane through,leaf water content,and the content of MDA synthesis reactions were better.Materials of C4,C6 and C11 compared to 8 other material had better relatively resistant to high temperature characteristics.C1 and C5 were relatively sensitive to heat.The results provided an important reference for resistance breeding of C.pubescens research.
