DNA C-values might be one of important indices in the evaluation of angiospermous invasiveness. To test this viewpoint, we compared DNA 1C-values and basic genome sizes in 3,676 angiosperms. The results suggest that:(1) the two nuclear values vary greatly among different groups, e.g., significantly higher in herbs than in trees, in monocots than in dicots, in perennials than in non-perennials;(2) the two nuclear values both have significant effects on plant invasiveness, especially in herbs, dicots, monocots, perennials, non-perennials, diploids, polyploids, Compositae, and Poaceae, while not significant in trees and Fabaceae.
DNA C值与被子植物入侵性密切相关,为考察应用DNA C值评估被子植物入侵性的可靠性和局限性,我们统计分析了全世界范围内3676种被子植物的DNA 1C值(配子未发生DNA复制时的染色体DNA含量)及基因组大小(单个染色体组的DNA 含量),结果表明:1)DNA 1C值和基因组大小在被子植物不同类群中差异极大,例如在草本植物中显著高于木本植物,单子叶植物显著高于双子叶植物,多年生植物显著高于非多年生植物;2)两项指标都与被子植物入侵性显著负相关,尤其是在草本植物、双子叶植物、单子叶植物、多年生植物、非多年生植物、二倍体、多倍体、菊科和禾本科中,然而在木本植物、豆科植物中其与植物入侵性无显著关系。

These large differences were predominantly caused by differences in numbers of annual dicots and perennial, mainly woodland dicots while the higher total species numbers in the Netherlands were mainly the result of an increase in all annual species.
这些大的差异主要是所造成的差异,在人数每年双子叶植物和多年生,林地主要是双子叶植物,而高占总种数的数目,在荷兰,主要是由于增加了,每年都种。
