| 摘 要： | 【研究目的】研究水葫芦生物学特性的多态性，以期为研究生态学特性和合理防治提供理论依据。【方法】采集来自鱼塘、污水沟、池塘和清水饲养的水葫芦植株，分别观察根、茎、叶的形态、大小，记录数据并拍照。【结果】水葫芦在有根系和不带有根系的情况下都能萌发新根。水葫芦叶片形态具有多态性，多态性的表现程度应与养殖的水质相关。水葫芦的叶片生长具有多态性，有独立成叶的或是带有包叶等，并且其中部分叶片在生长过程能形成新的根状茎，长出上长下短的新根，从而发育成新株。【结论】水葫芦具有很强的生长能力，其生物学特性具有多态性.

| Abstract: | OBJECTIVE] to study the polymorphism of biological characteristics of Eichhornia crassipes and supply theoretical evidences for studies on it ecological characteristics and reasonable control. METHOD]E. crassipes plants were collected from fish pound, sewage, pond and clean-water pond. The shapes and sizes of roots, stems and leaves of the E. crassipes plants were observed, recorded and taken photosRESULTS]E. crassipes could grow new roots when with root or without root. The shape of E. crassipes was polymorphous, which could be related to the water quality. The development of E. crassipes leaves had polymorphism too, growing independently or with wraping-leaf. Besides, parts of leaves could grow new rhizome companying with new roots of long on the top and short on the below, which formed a new plant late.CONCLUSION]E. crassipes possessed strong growth ability, and its biological characteristics were polymorphous. |
