鉴定橡胶无性系最常用的方法,至今仍然是目测繁殖器管的特征和胶树的形态特点,如树干和分枝的生长性状,叶片的形状、大小、颜色等。显而易见,这种方法不仅受鉴定者鉴别能力的影响,而且也受植株立地环境的影响。应当根据无性系的遗传性状来进行鉴定。克莱尔(Clare)等在1968年讲过,脱氧核糖核酸(DNA)中碱基顺序的差异是一种生物化学特性,这种特性用于微生物的分类是最有说服力的。另一方面,核酸中的碱基顺序可确 The most commonly used method to identify rubber clones is still to visualize the characteristics of the reproductive tube and the morphological characteristics of the gum tree, such as the growth traits of the trunk and branches, the shape, size and color of the leaves. Obviously, this method is not only affected by the identification ability of the appraiser, but also affected by the site environment of the plant. The clones should be identified based on their genetic traits. Clare et al. (1968) reported that the difference in nucleotide sequence in DNA is a biochemical characteristic that is most convincing for the classification of microorganisms. On the other hand, the nucleotide sequence in the nucleic acid is correct
