我于1983年—1987年对经过贮藏后的杂交稻种子糙米外观品质与发芽率关系方面进行过试验.现将结果摘要如下: 1、1984—1985年,原始发芽率(?)87%的种子批. (其中弱质糙米含量13—18%)在普通贮藏(7个月)到播种期时,发芽率下降至70%。(种子贮藏含水份13.5—14%). 2.1986年—1987,在常规条件贮藏13个月的杂交稻种子中,弱质糙米发芽力全部丧失. 3.1987我将新收获的杂交稻种子在规定条件下浸种一天置床2天后把不能萌发的种子逐粒去壳检验,发现死米占66%,弱质米占31%。
I tested the relationship between the appearance quality and the germination rate of the post-storage hybrid rice seeds from 1983 to 1987. The results are summarized as follows: 1. From 1984 to 1985, 87% of the original germination rate (?) Seeds Batch (where the weak brown rice content of 13-18%) in the ordinary storage (7 months) to sowing time, the germination rate dropped to 70%. (Seed storage moisture content 13.5-14%) .2 1986-1987, under normal conditions for 13 months hybrid rice seed, weak brown rice germination all lost 3.1987 I will newly harvested hybrid rice seeds in the conditions specified After soaking for 2 days, the seeds which could not germinate were peeled and shell-tested for 2 days. It was found that dead rice accounted for 66% and weak rice accounted for 31%.
