摘要:越南青冈与毛叶青冈同是壳斗科青冈属常绿乔木。越南青冈分布局限,为极危种,而同域毛叶青冈分布较为广泛,两者之间种存在自然杂交。本论文以越南青冈和毛叶青冈为研究对象,通过进行对两种青冈种子萌发和幼苗生长观测试验,对比其生长特性。结果表明:越南青冈与毛叶青冈在幼苗时期形态较为相似,不易区分,但在生长于生理特性方面还是略有不同的。例如毛叶青冈的株高及茎粗增长趋势变化较为平稳,而越南青冈株高及茎粗增长趋势的变化较为明显。5162

Comparison of Seeding stage growth characteristic in Cyclobalanopsis austrocochinensis and Cyclobalanopsis kerrii
Abstract:Cyclobalanopsis austrocochinensis and Cyclobalanopsis kerrii are both evergreen treeof Fagaceae Cyclobalanopsis.Cyclobalanopsis austrocochinensis distributed restrictively in North Vietnam and South West of China with only 3 populations and it is a critically endangered species. Cyclobalanopsis kerri is a wide spread common species.Furthermore,and there is a natural hybrid between the two species.This study is about Cyclobalanopsis austrocochinensis and Cyclobalanopsis kerrii,and to compare the growth characteristic of the two species through research on characteristic of seed germination and seedling growth.The results show that,although
The morphology response of Cyclobalanopsis austrocochinensis and Cyclobalanopsis kerrii are familiar in their seeding stage,there are some differences between Cyclobalanopsis austrocochinensis and Cyclobalanopsis kerrii in growth characteristic. The trend growth of heights, diameters of Cyclobalanopsis kerrii is steady,but the trend growth ofThe heights, diameters of Cyclobalanopsis austrocochinensis is not.
