摘要：

为了阐明茶条槭叶对环境的适应性变化，对七里峪茶条槭海拔分布范围(1200~1900 m)内叶绿体色素的差异及其沿海拔梯度的变化规律进行研究。结果表明：叶绿素a、叶绿素b和叶绿素(a+b)存在显著或极显著差异，叶绿素含量沿海拔梯度的变化呈现出一定的规律性。其中，叶绿素a、叶绿素b和叶绿素(a+b)含量均随海拔的升高先升高，在D(1500 m)或E(1600 m)达到最大值，然后随海拔的升高逐渐降低。而叶绿素a/b随海拔的升高呈“下降—升高—下降”的趋势。回归分析结果显示，海拔梯度上影响茶条槭叶绿素含量的土壤因子主要是土壤pH、土壤全磷、速效磷和有机质。1500~1700 m海拔区域是七里峪茶条槭适宜的生长范围。

Abstract:

In order to understand the leaf trait variations of Acer ginnala and the integrative effects of topography and soil nutrients on these changes, the author did a survey about the chloroplast pigment differences and the change patterns of the leaf chloroplast pigments along elevation gradients (1000-1800 m) within the distribution range of Acer ginnala in Qiliyu. The results showed that: there were significant or very significant differences of chlorophyll a, chlorophyll b, and chlorophyll (a+b) between various populations. There were also significant variations of the chlorophyll a, chlorophyll b, and chlorophyll (a+b) between different elevation gradients. With the increase of elevation gradients, the chlorophyll a, chlorophyll b, and chlorophyll (a+b) content of Acer ginnala populations increased gradually, reached to a peak at the elevation of D (1500 m) or E (1600 m) and then decreased gradually. The change pattern of chlorophyll a/b was firstly decreased, following increased and then decreased with the increase of elevation gradients. Moreover, regression analysis between chloroplast pigments and soil factors suggested that pH, soli total phosphorus, available phosphorus and soil organic matters were important influenced factors. The best growing elevation for Acer ginnala in Qiliyu was from 1500 m to 1700 m elevation.Key words Acer ginnala; chloroplast pigments; elevation gradients; Qiliyu
