瓠瓜(Lagenaria siceraria(Molina)Standl.)原产于我国,其变种多,结果习性特殊,是一个研究植物性别表现的好材料。关于瓠瓜的性别表现及其控制,过去的试验表明,瓠瓜的每一叶腋只生一朵花。不是雄花,就是雌花,乙烯利处理可以促进瓠瓜多生雌花,少生雄花。但这些试验多局限于瓠瓜的一个变种“杭州长葫芦”(var.hispida Hara)。本试验以瓠瓜的不同变种为材料来研究其性别表现及其激素控制。  相似文献

Guangdougen is generally known as Shandougen.  It is a  traditional Chinese drug.  It can be used as antipyretic,  antidote,  anodyne or antiinflammation ag- ent.  In recent years,  some compounds (alkaloids,  flavones and a new glycoside) such as cytisine,  matrine,  oxymatrine,  pterocarpin and isoprenyl chalcone,  have been isola- ted from roots of Guangdougen for medicinal purposes. They give effects of antiarrhy- thmia,  anticancer or antiulcer.       A recent investigation reveals that the Guangdougen comes from Sophora tonki- nensis Gagnep. (syn. Sophora subprostrata Chun et T. Chen) and Sophora tonkinensis Gagnep. var. polyphylla S. Z. Huang et Z. C. Zhou,  var. nov.      Gnangdougen is geographically restricted to SE. and NW. Guangxi and SE. Gui- zhou and Yunnan (103-109°E,  22-26°N). They have an ecological preference for li- mestone regions,  very commonly growing in mountains of 500-800 m alt.  相似文献
