摘  要：
以目前生产上广泛应用的籼型恢复系航1号、航2号、明恢86、多系1号和R527为研究材料,以耐储藏的品种云恢290为对照进行人工老化(温度42°C,相对湿度88%)处理。结果表明,随着人工老化时间的延长,各品种含水量逐渐增加,其中云恢290的含水量增加速度最慢,明恢86的含水量增加速度最快;发芽率检测结果表明,各品种发芽率随老化时间的延长而下降,脂肪酶含量与老化后的发芽率呈负相关。人工老化30d后,云恢290的发芽率为74%,显著高于其他品种。测定不同时间段的人工老化处理前后各品种主要化学成分变化,结果表明,所有品种的蛋白质含量均没有显著变化,而淀粉和脂肪酶含量均有所增加。

摘  要：
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.
