Abstract:

Taking one-year seedling of Castanopsis tibetanafrom different geographical provenances of Jian’ou in Fujian，Enshi in Hubei，Liuyang in Hunan，Sangzhi in Hunan，Yongshun in Hunan as materials.Seedling height，seedling diameter and monolithic leaf area and other growth indicators were measured；meanwhile taking leaf of Castanopsis tibetanaseedling as material，net photosynthetic rate (Pn)，transpiration rate (Tr)，stomatal conductance (Gs)，intercellular CO₂ concentration (Ci)，chlorophyll total content (Ct)，the ratio of chlorophyll a to chlorophyll b (Chl a/b) were dynamicly monitored.Growth difference and photosynthetic characters of different provenances were comparatively analyzed，in order to provide theoretical basis for seedlings cultivation and the selection for excellent seedling source and protection of Castanopsis tibetana.The results showed that there were significant differences between five seedlings in seedling height，seedling diameter and single leaf area，and Enshi provenance was dominated.There was significant difference in net photosynthetic rate (Pn)，transpiration rate (Tr)，stomatal conductance (Gs)，intercellular CO₂ concentration (Ci)，chlorophyll total content (Ct)，the ratio of chlorophyll a to chlorophyll b (Chl a/b) between five provenances.Latitude，longitude and frostless period were the dominant factor restricted geographic variation of photosynthetic parameters.And the geographical variation of net photosynthetic rate was south-north variation.Considering all the factors，the seedlings in Enshi Hubei was the best provenance among the selecting provenance.
