- 摘要:
- 以“五彩椒”为试材，在其花芽分化期施用 15N- KNO3示踪，并采用促、抑花调控措施，研究了观赏辣椒穴盘苗氮素营养的运转分配规律及花芽分化机理。结果表明：生长中心在花芽分化前后发生了转移，在花芽分化前主要以根系为生长中心，在花芽分化后转移到地上部顶芽和叶片的生长和发育；幼苗体内氮素水平的高低对花芽分化起着重要作用，在花芽分化前后促、抑花处理根、茎中氮含量和15N的丰度均增加，而在花芽分化后促花处理顶芽和叶中氮含量和 15N的丰度均降低，相对较低的氮素含量水平有利于成花。
- Abstract:
- Taking ‘Wucai’ ornamental pepper as materials,during the stage of flower differentiation, 15N- KNO3 and hastening and checking treatment were used,the law of N distribution and the mechanism of ornamental pepper flower bud differentiation were studied.The results showed that grow center changed during the stage of flower bud differentiation.It was in root system before flower bud differentiation，but after flower bud differentiation，the grow center transferred to the ground department gradually.Meanwhile N level played an important role during the stage of flower bud differentiation，and the content of N and 15N in root and stem of all the treatments were increased，but after flower bud differentiation，the content of nitrogen and 15N in shoot and leaves of hastening treatment decreased.Which mean the low N was favorable to flower bud differentiation.
