柚木(Tectona grandis Linn.f.)是马鞭草科的高大乔木。木材极为贵重。原产于印度、马来亚热带地区。目前国内外广为引种栽培,主要依赖于种子繁殖。柚木种子种核骨质,富含单宁,被有毡状绒毛,不易透水透气,发芽比较困难。如不经催芽处理,不仅发芽率低,而且发芽过程往往延续数月,甚至超过一年,费时费工,影响育苗定植,是当前柚木造林中急待解决的问题。为了寻找柚木种子发芽规律,促进提早发芽和 Teak (Tectona grandis Linn.f.) is a tall tree Verbenaceae. Wood is extremely valuable. Native to India, the tropical region of Malaya. Currently widely introduced cultivation at home and abroad, mainly dependent on seed breeding. Teak seeds of nuclear bone quality, rich in tannin, was a felted villi, impermeable to water vapor, germination more difficult. If not through the germination treatment, not only the germination rate is low, and the germination process is often extended for several months, or even more than a year, time-consuming and labor-intensive, affecting seedling planting is the current teak afforestation in urgent need of solution. In order to find the law of teak seed germination, promote early germination and
