| 摘 要： | 以甘蓝型油菜品种‘福油-4’、RG-8晚熟及其早熟突变体（RG-8M）为材料，研究成花过程中叶片多胺代谢的变化规律，结果表明：较低含量的多胺（主要是腐胺和亚精胺）有利于油菜花芽分化的起始，含量的增加有利于花芽的发育，抽薹越早的品种其体内多胺含量越早到达较高水平。多胺氧化酶（PAO）活性的变化趋势与多胺总量的变化较一致，它们之间呈极显著正相关，说明高活性的PAO也是有利于成花的。 |

| Abstract: | Dynamic changes of polyamine metabolism during flower formation in rape(Brassica Napus L.) were studied with three cultivars ' Fuyou No.4 ',RG-8 and its early-maturing mutant(RG-8M) .The results showed that the lower levels of polyamines(mainly putrescine and spermidine) were benefit to induct floral bud differentiation of rape.The higher levels of polyamines were benefit for floral bud development.And what ' s more,the earlier-maturing cultivar was earlier to reach the high level of polyamines.The PAO acti... |
