对植物种苗的研究,可以给植物分类学提供探索植物类群亲缘关系等系统发育方面的资料。同时可供植树造林、森林更新、森林资源调查等工作参考。本着以上的目的,我们开始对一些速生、珍贵树木进行了种苗方面的研究。下面仅介绍三种。一、合果含笑(Paramicheliabaillonii(pierre)Hu.)木兰科半落叶高大乔木,树高达35m,胸径1m 以上,树干通直。分布于云南西双版纳、恩茅、红河、临沧等地海拔500—1,700m的热带季雨林及常绿阔叶林内;国外印度、泰国、缅甸、越南也有分布。本材结构细致,花纹美丽,材质坚韧,耐朽抗虫性好,适用于建筑,枕木,高级家具,室内装饰,高级贴面胶合板以及制造枪托,快艇,手榴弹柄等军工用材。果肉质球果状,圆筒形,种子扁圆,具红色假种皮。果熟期8—10月。果实采收后
Research on plant seedlings can provide phylogeography to the phylogeny of exploring phylogenetic relationships among plant groups. At the same time for afforestation, forest renewal, forest resources survey work reference. In the light of the above objectives, we have started to study the seedlings of some fast-growing and valuable trees. The following describes only three. First, the fruit smiling (Paramicheliabaillonii (pierre) Hu.) Magnoliaceae semi-deciduous tall trees, trees up to 35m, diameter at least 1m, trunk straight. They are distributed in tropical monsoon forests and evergreen broad-leaved forests at altitudes of 500-1,700m above sea level in Xishuangbanna, Ngoc Mang, Honghe, Lincang, etc. There are also overseas distributions in India, Thailand, Myanmar and Vietnam. The material detailed structure, beautiful patterns, tough materials, resistance to rotten insect resistance, suitable for construction, sleepers, high furniture, interior decoration, advanced veneer plywood and manufacturing stock, speedboats, grenades and other military supplies. Fruit fleshy-globose, cylindric, seeds oblate, red-leaved seed coat. Fruit ripening from August to October. After the fruit is harvested
