Methods Seeds were collected at the Wanfoshan Natural Reservation Region from July to October 2011. Air-dried weight of 100 diaspores, including seeds and indehiscent and single-seeded fruit, was measured for each of three replicates. Seed mass variation and ecological significance were analyzed. Important findings Seed mass varied greatly from 10–3 g to 103 g. The seed mass distribution of various species was normal, as checked by the Kolmogorov-Smirnov Test. The mean weight of 1 000 diaspores was 21.487 g. The seed mass of Momordica cochinchinensis (1 775.192 g) and Aeginetia indica (0.006 g) were the heaviest and lightest, respectively. More than 60% of the species had a mean seed mass between 0.1 and 10.0 g. The seed mass of 105 species was < 1.0 g. There were significant differences of seed mass among 68 families and eight life forms, as determined by one-way analysis of variance (p < 0.001). Pearson’s relative analysis showed a negative relationship between seed mass and phylogeny (r = –0.079, p = 0.048) and a positive relationship between seed mass and life forms (r = 0.220, p < 0.001). A significant difference was also detected at the generic level (p < 0.001) in some families, including Compositae, Poaceae, Cyperaceae and Rosaceae. %K life form %K phylogeny %K seed mass %K Wanfoshan Natural Reservation Region
