Abstract

From in-vitro protein synthesis studies it has been shown that in Petunia hybrida (clone W166K, incompatibility genes S1S2) the ovary is stimulated to synthesize proteins before the pollentubes reach the ovary. A difference in protein metabolism is detected after self- and cross-pollination. On the basis of this result has been concluded that a signal has to be sent from the stigma or the style towards the ovary which induces the changes in metabolic activity. The signal must be different for cross- and self-pollination.

摘要

体外蛋白质合成研究表明，在矮牵牛（克隆W166K，不亲和基因S1S2）中，在花粉管到达子房之前，子房就被刺激合成蛋白质。自花授粉和异花授粉后检测到蛋白质代谢存在差异。基于这一结果得出结论，必须有一个信号从柱头或花柱传向子房，从而引起代谢活性的变化。异花授粉和自花授粉的信号肯定不同。
