Analysis on fruit type and seed size of woody species in Quercus phillyreaoides community
摘要
Abstract
The morphological features of fruit and seed size of 41 woody plants in the Quercus phillyraeoides community of Jiangshi Nature Reserve are measured. The results show: (1) All of the fruits in the community, sarcocarp and dry fruit occupy 56.92％ and 43.08％ respectively, and the ratio of both is close to 1∶1. (2) Compared to the others', the distribution pattern of fruit type is effected by the water and temperature, which means the dry fruit is more in the western and less in eastern, or vice versa to sarcocarp. (3) Variance considering three dimensions(length,width and depth) is used to describe diaspore shape,which shows there is wide range of the seed size with maximum value 0. 537 1 and minimum value 0.003 1,and most of the them are less than 0.4. (4) Things considered from seed weight, 1～10 g and 10 ～100 g of hundred seed weight occupy the ratio about 39.02％ and 21.95％ respectively. (5) The difference of seed size is not only existence in families, but also in life form, which is consistent with previously published studies. (6) The lower diversity of woody species in the Quercus phillyraeoides community may be resulted by the single distribution of seed. Finally, the ecological fitness of fruit and seed in the community are discussed.关键词
