摘  要:
以多叶羽扇豆为试材,研究了高温胁迫对多叶羽扇豆的生长及生理指标的影响,以期探讨多叶羽扇豆的耐热性。结果表明:在高温条件下,多叶羽扇豆花期缩短,结实量降低,低温24℃,高温35℃以上7d,多叶羽扇豆开始萎蔫死亡;高温胁迫下,多叶羽扇豆细胞内的电解质外渗,膜透性增大,细胞膜受到损伤,叶绿素含量降低,丙二醛含量增高,超氧化物歧化酶活性、过氧化物酶活性升高。

摘  要:
Taking the Lupinus polyphylla Lindl.as experimental material,the effect of high temperature stress treatment on growth and physiological indices of Lupinus polyphylla Lindl.were studied,the heat tolerance of Lupinus polyphylla Lindl.were studied.The results showed that the high temperature stress treatment could shorten the florescence, decreased the seed output.Lupinus polyphylla Lindl.would death when the low temperature at 24℃ and high temperature at 35℃ continuously seven days.The high temperature stress treatment could increase electrolyte leakage and membrane permeability of leaf cells,the chlorophyll content decressed,MDA content,SOD activity and POD activity increased.
