摘要: 多项指标测定的结果表明：7种源中缙云和戴云山部分苗根易老化，影响成活率。经变异聚类，临安和缙云、黄山和开化种源分聚2类，金寨、戴云山、天台种源各自成1类。苗茎高生长主要出现于前期，中后期为针叶和根生长的主要阶段，总生长量接近程度与变异接近程度不对应一致。生长中期各种源苗体细胞膜调控节律与种源聚类的结果是相应一致的，各种源胞膜透性的变化与变异接近程度有一定关系。7种源在气温30℃，电解质外渗率均上升时，开化种源有较强的控制物质外渗的能力。核酸量变幅度DNA大于RNA，以RNA/DNA相比，开化种源最大，临安最小。RNA生成量与苗根生长有密切关系。二氧化碳利用能力以缙云和天台种源最高，其次是开化、黄山、金寨、戴云山、临安等种源。此可作为优良种源苗期初选的依据。

Abstract: The results of study on the various indices of 7 provenances showed that the root s ageing of some seedling from Jinyun and Daiyunshan affected the surival rate. The 7 provenances were divided into 5 groups: Lin an-Jinyun, Huang shan-Kaihua, Jinzhai, Daiyunshan and Tiantai. The seedling growth in stem mainly started in the earlier stage, while its growth in conifenous and root in the middle and later stege. The closing degrees of gross increment of provenance and the variation were inconsistent. The regulation rhythm of cell membrane and the cluster result of 7 provenances were consistent in the middle period. The variable rhythm of membrane permeability directly was influenced by the closing degree of variation, when the outside permeation of the elect rolytes of 7 provenances at 30℃ increased. Kaihua provenance had a stronger power of controlling the permeation. The range of quantative change of nucleic acid was greater than that of RNA. According to the comparison of DNA a nd RNA, Kaihua was in the maxmum position, and Lin an in the minimum posi tion. Major factor for the grouth of seedling root was the generaring quantity of RNA. The ulilization power in CO2 of Jinyun and Tiantai was much stronger than that of Kaihua, Huangshan, Jinzhai, Daiyunshan and Lin an, which could be considered as a basis for the initial separation of seedling stage of pine provenance.
