摘要
本文对缫丝花(RosaroxburghiTrat)与单瓣缫丝花(R.roxburghif.normalisRehd.etWils)的根、茎、叶、花进行了形态和解剖结构观察。结果表明:1.两种缫丝花营养器官形态与结构基本相似;2.二者的花托-托附杯在形态上明显不同,缫丝花呈深碟状,单瓣缫丝花呈壶状;3.缫丝花的重瓣花瓣是由雄蕊和/或者离心皮雌蕊发生瓣化形成的。表明雄蕊、心皮与花瓣在起源上是同源的。
This paper dealt with the morplology and anatomy of roots, stems, leaves, flowers of the Rosa roxburghii and R roxburghii f normalis The observations were as follows:1 The anatomical structures of vegetative organs in Rosa roxburghii were fundamentally alike to that in R roxburghii f normalis 2 The receptacle hypanthium in R roxburghii f normalis was deep small dish, but that in R roxburghii f normalis was flask shaped.3 The petals of the multiplicate flower in R roxburghii were from andropetalous or and gynpetalous. The petaloid phenomenon of the stamens and apocarpous gynoecium shows that stamen, carpel and petal are homology in origin.
