摘　　要：对杉木种子发育生理及涩籽形成原因的研究结果表明 :随着胚的分化发育 ,雌配子体 (胚乳 )和胚的干质量、体积及生物大分子 (总核酸、蛋白质和类脂 )含量均不断增加 ,一直持续到种子成熟。败育的杉木涩籽中存在着凝集素类物质 ,它的存在与败育无关 ,而在贮藏蛋白的形成中有作用。败育的杉木涩籽中只积累较多的脱落酸 ,说明了败育涩籽的衰败和失活。Research on development physiology of Chinese fir ( Cunninghamia lanceolata ) seeds and causes of formation of abortive seeds showed that,with embryo differentiating and developing,female germanium and embryo increased their dry weight,volume and biological macromolecules (DNA,RNA,proteins,liquids) till seed matured.The abortive seeds contained lectins.This matter played a role in forming storage protein,independent of abortion.The abortive seeds only accumulated large abscises acid,which caused the abortion and inactivation.From the results of investigation,some measures of decreasing abortion rate were proposed.
