Studies on the critical period of floral differentiation and changes of endogenous hormone contents in the decapitated seedlings of cucumber(黄瓜去顶苗花分化临界期的确定及内源激素的动态变化)

通过在诱花和诱芽培养基之间转换培养，发现黄瓜去顶苗花分化临界期是培养后的第5至6天（即去顶后的3至4天）.对花芽分化初期子叶节中内源激素质量分数的测定表明，IAA质量分数在花芽分化初期处于较低水平，ZT质量分数呈下降趋势，GA3质量分数则出现升-降-升的波动状态.ZT/IAA、GA3/IAA比值的变化趋势相似，0至2天上升，2至3天下降，3至4天再上升.根据实验结果，联系黄瓜去顶苗成花的形态变化过程，对激素质量分数变化与花芽分化之间的关系进行了讨论....
