林木种子是发展林业生产的重要物质基础,而种子的播种品质又是计划生产的主要依据。地处热带地区的海南岛,树种繁多,尚无固定的种子基地,种源分散,立地条件复杂,物候期不一,因此,目前要一一准确地掌握林木种子成熟期和稳定的种子品质指标比较困难。为了热带林业的发展,我们从1963年开始进行热带林木种子品质检验工作,探索热带林木种子品质较稳定的各项指标,以供生产单位参考。先后对183个树种(包括一些外引树种)进行
Forest seed is an important material basis for the development of forestry production, and sowing quality of seeds is the main basis for planned production. Hainan Island, located in the tropical region, has a great variety of species, no fixed seed base, scattered provenances, complex site conditions and different phenophases. Therefore, it is necessary to accurately grasp the seed maturity and stable seed quality indicators more difficult. In order to promote the development of tropical forestry, we started the inspection of tropical forest tree seed quality in 1963 and explored the more stable indicators of the quality of tropical forest tree seed for reference by production units. Has 183 species (including some cited species)
