本文对凉水自然保护区8a生樟子松种源试验结果进行了全面总结。主要内容有:(1)研究了樟子松生长性状的地理变异规律,即呈现以纬向负向渐变之趋势,且具有明显的气候特征;经向变异是随机的;(2)形态、适应性、抗性等特征无明显差异;(3)在生长特性地理变异的基础上将樟子松10个采种点归并成2个地理种群和2个亚群,即大兴安岭北部种群(编号Ⅰ)和大兴安岭东南部与小兴安岭种群(编号Ⅱ),后者又分为红花尔基(Ⅱ—1)和卡伦山(Ⅱ—2)两个亚群;(4)以所划种群和亚群为单位进行年高生长节律分析;(5)以8D_(1·3)和8H的差异显著性测验结果为凉水自然保护区及毗邻地区初步选择了最佳种源(卡伦山),并以3、5、7、8a生树高生长的秩次相关分析进行了种源早期选择可能性验证。
This paper summarizes the results of the provenance test of Pinus sylvestris var. Mongolica 8a in the Liangshui Nature Reserve. The main contents are as follows: (1) The law of geographical variation of growth traits of Pinus sylvestris var. Mongolica was studied, that is, the trend of gradual change in zonal direction was presented, and the climatic characteristics were obvious. The variation of meridional direction was random. (2) (3) Based on the geographical variation of growth traits, the 10 seed-selection points of Pinus sylvestris var. Mongolica were merged into 2 geographic populations and 2 sub-populations, namely the northern Great Xing’an Mountains (No. Ⅰ) and Southeastern Daxing’anling and Xiaoxinganling population (No. Ⅱ), and the latter is divided into two sub-populations of Honghuaerji (Ⅱ-1) and Karen Mountain (Ⅱ-2); (4) (5) According to the results of 8D_ (1.3) and 8H difference significance test, the best provenance (Karen Mountain) was selected for the Liangshui Nature Reserve and the adjacent area, , 5,7,8a growth of tree height rank correlation analysis of seed provenance early selection possibilities.
