37科112种植物的4C DNA值变化范围为0.83 ~ 15.54 pg，变异系数为18.72倍。基因组大小从0.21 pg（Bixa orellana）到3.32 pg（Thespesia populnea）不等，相差15.8倍。木棉科的变异幅度最小（1.08倍），而豆科的变异幅度最大（5.0倍）。紫草科、樟科、锦葵科和锦葵科的4C DNA值普遍较高，> 10 pg，而Bixaceae、Caricaceae、Oxalidaceae和Santalaceae的4C DNA值较低，< 2.0 pg。这些数据进一步增加了我们对热带硬木DNA含量变异的认识。
The 4C DNA values of 112 species, belonging to 37 families have a range from 0.83 pg (Bixa orellana) to 15.54 pg (Thryallis angustifolia), showing a 18.72-fold variation. The genome size varies from 0.21 pg (Bixa orellana) to 3.32 (Thespesia populnea), with a 15.8-fold difference. The Bombacaceae has the minimum range (1.08-fold) of variation, while the maximum (5.0-fold) is shown by the Fabaceae. The Boraginaceae, Lauraceae, Malpighiaceae, and Malvaceae generally have higher 4C DNA values of > 10 pg, while the Bixaceae, Caricaceae, Oxalidaceae, and Santalaceae have lower values of < 2.0 pg. These data add further to our knowledge on variation in DNA amount in tropical hardwoods.
