摘要
以早熟禾和紫羊茅为材料,研究低温胁迫下植物叶片的电导率、叶绿素含量、可溶性糖含量、可溶性蛋白含量的变化。结果表明:在低温胁迫下两种植物的相对电导率升高;叶绿素含量逐渐降低;可溶性糖含量增加;可溶性蛋白含量增加。这些现象表明,短时间的低温已经对两种植物造成了伤害,各生理指标同低温胁迫有线性相关。
Conductivity of plant leaves,chlorophyll content,soluble sugar content and soluble protein content on low temperature stress in bluegrass and red fescue were studied.The results showed that relative conductivity of those two materials was increased.Chlorophyll content,soluble sugar content and soluble protein content were gradually decreased.These phenomena showed that short time low temperature had caused damage to two kinds of plant materials.The physiological indices had linear correlation with the low temperature stress.
