本文对华北夏大豆“齐黄１０号”和南方春大豆“苏８８—Ｍ１９”在４０℃热击２ｈｒ后，转到２５℃分别恢复处理２、４、６、８、１０ｈｒ。分析并比较了两者ＨＳＰ的变化。结果表明：随恢复期的延长，两种大豆ＨＳＰ的种类均在减少。累积量动态变化却有显著的区别，在恢复２ｈｒ时，“齐黄１０号”ＨＳＰ累积量急剧增加，尔后至１０ｈｒ时又逐渐减少；“苏８８—Ｍ１９”恢复２ｈｒ时，ＨＳＰ累积量大幅减少，尔后到１０ｈｒ时又逐渐增加。
In this paper, North China summer soybean “Qi Huang 10” and the southern spring soybean “Su 88-M19” heat shock at 40 ℃ 2hr, go to 25 ℃ resumed treatment 2,4,6,8,10hr. Analyzed and compared the changes of both HSPs. The results showed that with the extension of the recovery period, the types of HSPs in both soybean varieties decreased. However, there was a significant difference in the dynamic changes of cumulants. At the time of 2hr recovery, the HSP accumulation of Qihuang 10 increased sharply, and then gradually decreased from 10hr to later. The accumulation of HSP decreased significantly after 2hr of recovery of Su 88-M19 , Then gradually increased to 10hr.
