摘要
以农垦58S为材料,探讨了光敏色素调控农垦58S的育性转换与硝酸还原酶(NR)的关系。结果表明,NADH以每毫升0.2 mmol·L^(-1)对黄化苗的NR活性最强;预照光在24小时以内,NR活性随照光时间延长而呈极显著正相关;红光和远红光照射后,NR活性均有一定程度增高,红光的作用大于远红光,且红光与远红光能相互逆转。
The experiment was conducted on rice (Nongken 58S) with the attempt to study the possible relationship between the phytochrome-controlled fertility transformation and NR (nitrate reductase) activity. The results showed that NR activity was the highest in the eliolated seedlings treated with 0.2 mmol, L^(-1) NADH. When etiolated seedlings was exposed to light, the NR activity elevated significantly with the increase in lighting time within 24 ours. It was also revealed by lighting the plants with different wave-length that both red and far red ight strengthened NR activity, but the red had stronger effect on NR than the far red. Forthermore, the effect of R or FR on NR activity was mutual reverseable.
