油桐属与石栗属叶片核酸和蛋白质的比较研究

关于油桐属(Vernicia Lour.)与石栗属(Aleurites J.R.et G.Forst.)在分类学上分与合的问题,已经历了两个世纪的争论,长期以来油桐属不被承认,至今尚无定论。最近K.H.AiryShaw又将油桐属和石栗属重新分开。目前较多的植物分类学家接受了Airy Shaw的分类方法,即把油桐属和石栗属分为两个属,近期通过解剖构造和微观形态的研究,也支持了Airy Shaw的论断。本研究试图为此进一步提供一些生化论据。

A COMPARASION BETWEEN TUNG TREE''''S AND BELGAUM WALNUT'''' S LEAF PROTEIN AND NUCLEIC ACID CONTENTS

The authors used the leaves of Wood oil tree (Vernida montana Lour), Tung tree (V. fordii (Hems!) Airy Shaw), and Belgaum walnut (Aleurites moluccana (L.) Willd) as testing materials to study their differences of chlorophyll, free amino acid, protein, RNA and DNA contents. The results have shown that there is no difference between these two genera's DNA contents, but Belgaum walnut's chlorophyll and protein contents are higher than Wood oil tree's and Tung tree's, and on the contrary, its free amino acid and RNA contents are obviously lower than the Vernida's. Thus, from the biochemical view, it is reasonable that Airy Shaw has recently separated Vernida from Aleurites.
