摘要Leaf wax delta Dn-alkane values have shown to differ significantly among plant life forms (e.g., among grasses, shrubs, and trees) in higher plants. However, the underlying causes for the differences in leaf wax delta Dn-alkane values among different plant life forms remain poorly understood. In this study, we observed that leaf wax delta Dn-alkane values between major high plant lineages (eudicots versus monocots) differed significantly under the same environmental conditions. Such a difference primarily inherited from different hydrogen biosynthetic fractionations (epsilon(wax-lw)). Based upon a reanalysis of the available leaf wax delta Dn-alkane dataset from modern plants in the Northern Hemisphere, we discovered that the apparent hydrogen fractionation factor (epsilon(wax-p)) between leaf wax delta Dn-alkane values of major angiosperm lineages and precipitation dD values exhibited distinguishable distribution patterns at a global scale, with an average of -140% for monocotyledonous species, -107% for dicotyledonous species. Additionally, variations of leaf wax delta Dn-alkane values and the epsilon(wax-p) values in gymnosperms are similar to those of dicotyledonous species. Therefore, the data let us believe that biological factors inherited from plant taxonomies have a significant effect on controlling leaf wax delta Dn-alkane values in higher plants.
