摘  要：
对浙江天童山常绿阔叶林米槠、栲树和苦槠的林缘与林内种群的种子性状进行比较研究。结果表明:米槠林缘种群的种子长度、宽度、长宽比和质量都显著大于林中种群(P<0.001);栲树林缘种群的种子长度、宽度、长宽比和质量也显著大于林中种群(P<0.001);苦槠林缘种群的种子长度、宽度和质量显著大于林中种群,但长宽比无显著差异(P=0.924)。总体来说,森林的边缘效应是导致林缘种群种子性状优于林内种群的主要生态学机制。

摘  要：
The seed traits of edge-and within-forest populations of Castanopsis carlesii,C. fargesii and C. sclerophylla were compared and studied in Tiantong Mountain,Zhejiang Province. The results showed that: the seed length,width,ratio of length to width,and quality were significantly larger than within-forest population of Castanopsis carlesii(P < 0. 001); for Castanopsis fargesii,seed length,width,the ratio of length to width,and weight were also statistically greater in edge than in within-forest population(P < 0. 001); and Castanopsis sclerophylla seed length,width and weight were evidently higher than within-forest population, whereas there was no significant difference of ratio of length to width between two populations. In conclusion,edge effect of forest was the main ecological mechanism leading to better seed traits in edged-forest population than in within-forest population.
