| 摘 要： | 关于激素在果实生长发育过程中的作用 ,前人曾进行过大量的研究 ,并取得了许多宝贵的成果1,2 ] ,而对银杏 (ＧｉｎｋｇｏｂｉｌｏｂａＬ .)种子的相关研究却很少。银杏作为一种古老的裸子植物 ,其种子的生长发育与一般的裸子植物又有不同 ,它的胚珠直接着生在短枝上 ,没有了一般裸子植物的球果构造 ,从表面上看很类似于杏 (Ａｒｍｅｎｉａｃａｓｐｐ .)、桃 (Ａｍｙｇｄａｌｕｓｓｐｐ .)等的生长发育过程。本文从分析银杏种子生长发育的一般特点出发 ,研究了银杏种子生长发育与内源激素含量的关系 ,旨在探索银杏种子生长发育的一般规律 ,…

| Abstract: | The relationship among growing process,drops and endogenous hormones contents on Ginkgo biloba seeds were studied. The results showed that the growing curve of seed is S shape. The period of seed expanding late from the beginning of May to the middle of July. There is a remarkable relation between seed growth and content of endogenous hormones in seeds. The contents of IAA,ZR and ABA are higher whereas GA 3 is lower in the period of flourishing florescence, then the content of IAA,ZR and ABA significantly decreased but GA 3 increases after pollination. In the period of seed expanding, the content of IAA and ZT gradually increases again, and reaches another peak at the beginning of July, then both of them steady decrease, but at the same time the content of ABA gradually increases until the seed ripe. In a word, the function of GA 3,IAA,ZR and ZT seem to prompt the seed growth, whereas ABA concerns with seed mature and drops. There are two times drops of Ginkgo biloba seeds. The drops are related to hormones. |
