长白落叶松种源试验是在凉水自然保护区进行的。本试验共选择了11个种源(其中带岭种源属于兴安落叶松作对照用的)。试验结果:种源间高生长差异极显著,大石头种源最好,其高生长量分别超出所有种源总平均高生长量的17.51％、带岭(对照)种源的32.32％、最差小北湖种源的59.87％。文中还进行了多变量综合分析与常规用树高选择最佳种源的秩次相关分析。目前,大石头种源可暂作为凉水及其邻近地区的最好种源。
Changbai larch provenance test was carried out in Liangshui Nature Reserve. A total of 11 provenances were selected for this experiment (the Belt Ridge provenances belong to Larix gmelinii for comparison). The results showed that there was a significant difference in high growth among provenances, with the best provenance of boulders. The high growth exceeded the average growth of all provenances by 17.51% and 32.32% respectively, 59.87% of Xiaobeihu provenance. The article also conducted a multivariate comprehensive analysis and conventional tree height selection of the best provenances rank correlation analysis. At present, the boulder provenance can temporarily serve as the best provenance for cold water and its adjacent areas.
