| 摘 要： | 对来自27个不同种源的云南松(Pinus yunnanensis Fr.)进行苗期试验,测定苗高和地径生长量,并对其21个月生的苗高和地径进行方差分析。结果表明:不同种源的云南松在相同试验条件下,其苗高和地径差异极为显著,初步选出其苗高超过对照(安宁种源)175.3—205.3％的10个种源,可供造林试验用种。本试验还对云南松形态特征的地理变异规律及其相互间的关系进行了初步探讨。

| Abstract: | A seedling test including the measure and analysis of variance of the height and diameter at ground level of 21-months old seedlings of 27 different provenances of Pinus yunnanensis Fr. was carried out. The result showed that the variations of the height and diameter of different provenances of Pinus yunnanensis planted in the same experimental plot were very remarkable. We have primarily selected 10 provenances of Pinus yunnanensis of which the height increment are faster than those of control and which can be used in forest experiment. In addition to a primary study of the geographical variations of morphological characteristics and their relationship also described. |
