油松小孢子叶球性反转现象的观察

Observation of sex reversal phenomenon of Pinus tabulaeformis microstrobilus

通过对油松小孢子叶球性反转现象的观察,结果表明:已经完成分化的正常小孢子叶球发生了性反转,从其顶端的小孢子叶开始向基部逐渐转变成大孢子叶,直至整个小孢子叶球转变成异常的大孢子叶球;异常大孢子叶球具有接受花粉的能力,并在枝条上发育成为蔟状着生的小球果。

Result from observation of sex reversal phenomenon of Pinus tabulaeformis microstrobilus shows that: differentiated normal microstrobilus had a phenomenon of sex reversal,which changed to megastrobilus gradually from the top to the base,until the entire into unusual megastrobilus;the unusual megastrobilus had a ability to accept pollen,and developed into fascicled small cone on the branches.
