大豆短日诱导期间,顶芽内的玉米赤霉烯酮含量始终比连续光照下的高;在SD诱导的第2天,顶芽中总细胞分列含量1.9倍于CL下的CTK含量;游离氨基酸也一直维持较高含量水平;同化物中,除SDD诱导的2天可溶米如今较高和诱导结束时的蔗糖含量较CL下的高外,其余的测定中CL下的可溶糖、蔗糖及淀粉含量CL下均比SD下的高。 |

Abstract: |
Using Glycine max L. cv. Zao 12 as the experiment material, changes of plant hormones and assimilates in the apical bud were studied. The results showed that the con-tent of endogenous zearalenone(ZEN) was higher than that of CL treatment in the process of photoperidic induction. In the 2nd day of induction, the cytokinins(CTK) contents in apical bud were 1. 9 times higher than that in CL condition. The content of free amino acids in plants growing under SD was higher than that of CL treatment. The content of soluble sugar was higher in 2nd day of induction and sucrose content was 1. 5 times higher than in CL. According to these results, we might conclude that plant hormones and assim-ilates might play very important role in the photoperiodic induction period of soybean. |
