低温胁迫对水稻幼苗抗冷性的影响

Effect of low-temperature stress on cold-resistance ability of rice seedlings

分析探讨了低温胁迫恢复正常温度 2 d后 ,水稻幼苗叶绿素含量、根系活力、过氧化物酶活性及细胞膜透性 4个生理指标的变化及其与抗冷性的关系 。

Changes of 4 physiological indexes (Chlorophyll content roots activity,POD activity and penetrability of cell membrane)of rice seedlings and the relations of them to cold-resistance ability from 3 different genotypes were studied 2 days after low-temperature treatment.And select the one of higher cold-resistance ability.
