摘要
红花莼菜生殖器官的外部形态和内部的解剖结构研究结果表明:两性花,花被片6枚;雄蕊17~27枚,没有腺毛;心皮6~11枚,离生单雌蕊,上位子房,其柱头、花柱、子房密生腺毛;边缘胎座,胎座柱状,与珠柄垂直接合,接合处关节明显,下垂式弯生胚珠1~3枚.通过对红花莼菜生殖器官形态和解剖结构的分析,支持莼菜属从睡莲科划分出来。
Morphology and structure of reproductive organs of Brasenia schreberi Gmel were observed and anatomized.The results were as follows:bisexual flower,tepal 6,stamen 17~27 ,no glandular hairs;carpel 6~11,separation,superior ovary;densely coveres glandular hairs on stigma,style,ovary,marginal placentation,columnar placenta and funiculus vertical joint,joit is quite clear,campylotropous ovules 1~3,hang down. Its microstructures were analysed,the results have proved this classified point that Brasenia parted from Nymphaceae and setted up Cabombaceae.
