为探讨长白落叶松(Larix olgensis Henry)天然林结实的规律性,本文对长白山林区天然落叶松球果类型作了比较研究。根据球果类型,把该树种划分为具有四种球果类型的林木,并进一步探索了长白落叶松四种果型林木的结实与有关因子相互影响、相互制约的客观规律。发现长白落叶松四种果型林木的结实多少及其种子品质的优劣与立地条件、发育阶段、生物因子等密切相关;而四种果型的球果颜色、形状、大小、种鳞结构以及鳞片数目等同上述因子无关。
In order to explore the regularity of the Larix olgensis Henry natural forest, the types of natural larch cones in Changbai Mountain were compared. According to the types of cones, the species was divided into four kinds of coniferous trees, and further explored the law of interaction and mutual restraint of the four kinds of fruit trees of Larix olgensis. The results showed that the fruit size and the seed quality of the four kinds of fruit trees were closely related to the site conditions, developmental stages and biological factors. The color, shape, size, The number of scales is not related to the above factors.
