檀香种子没有真种皮,其假种皮是由胚乳的外层变坚硬后形成的。种子休眠期至少有50天。在正常情况下,休眠期过后至少30天才开始发芽,超过140—150天以上,发芽率可达80％。Ramaswamy(1949)曾用椰子水处理檀香种子进行催芽,但无效。Srimathi等(1969)曾报道,除去檀香种子的坚硬外壳可加速其发芽,即在9天后开始发芽,30天内发芽率达80～85％。本研究介绍的是,在田间条件下,促

Sandalwood seeds have no true seed coat, and their fake seed coat is formed by the outer layer of the endosperm becoming harder. Seed dormancy for at least 50 days. Under normal circumstances, dormancy period at least 30 days before germination, more than 140-150 days, the germination rate of up to 80%. Ramaswamy (1949) used coconut water to stimulate sandalwood seeds to germinate but did not work. Srimathi et al. (1969) reported that the removal of the hard shell of sandalwood seeds accelerates their germination, ie germination starts after 9 days and the germination rate reaches 80-85% within 30 days. This study introduces that under field conditions, promote
