赤霉素促进松属树种开花结实的研究进展

The research progress of promoting Pinus seeds of trees flowering and seeding of gibberellin

本文对国内外应用赤霉素(GA_3、GA_(4+7))在促进松属树种开花结实方面的研究进展进行综述,对比分析GA_3、GA_(4+7)在促进松属树种开花结实方面的影响程度及影响赤霉素促进效果的其他因素,大量研究结果表明,GA_3多用于杉科及柏科树种开花结实促进技术的研究,而非极性GA_4+GA_7混合物在促进松属树种开花结实方面研究较多。

The research progress of promoting Pinus seeds of trees flowering and seeding by using gibberellin（ GA3 ,GA4＋7 ） was summarized in this paper. The effect degree of promoting Pinus seeds of trees flowering and seeding of GA3 and GA4 ＋7 and the other factor of affecting promoting effect of gibberellins were comparatively analyzed. A large number of research result showed that GA3 was mostly used to the research of flowering and seeding promoting research of Taxodiaceae and Cupressaeeae seeds of trees. Furthermore, there were more researches on promoting Pinus seeds of trees flowering and seeding of nonpolar GA4 ＋ GA7 mixture.
