水稻种子老化后的生理特性初步研究
Preliminary Study on Physiological Characteristics for Rice Seed After Aging
摘要
Abstract
The artificial aging was carried out with most commercial restore lines, such as Hang 1, Hang 2, Minghui 86, Duoxi 1, R 527 and control endurable storage variety Yunhui290 under the condition of the temperature 42 C, humid 88%. The results indicated that the water content of theses varieties was increased gradually, in which the content of increased water for Yunhui 290 was the least and that for Minghui 86 was most with the prolonging of aging. Meanwhile the germination rate of the varieties decreased gradually, in which germination rate of control " Yunhui 290" was 74%, higher than the other varieties significantly after artificial aging 30d. After water content equilibration of all varieties, artificial aging in different stages were performed and the main components of these varieties were measured by conventional chemical methods before and after aging treatment. The results indicated that the content of proteins of each variety had no significant difference, but the content of starch and lipases were increased after aging.关键词
