摘要
为了探讨酸角(Tamarindus indica Linn)种子发芽状况与生态学习性,研究了质量分数98%浓硫酸浸种处理及低温处理的酸角种子在不同的温度条件的发芽情况.结果表明,酸角种子发芽温度范围较广,在15～30℃都能发芽.经过硫酸处理的酸角种子,具有很高的发芽率,以25℃下30 min处理下效果最为明显,发芽率最高,为100%;25℃下15 min处理,20℃下30 min,45 min处理,15℃下45 min处理的种子发芽率也较高,达到了90%以上;低温处理对酸角种子的萌发也有一定的促进作用,发芽率最高可达75%,但效果不如硫酸处理的明显.
To explore the germination rate and eco-physiological trait of tamarindus indica Linn seeds,the germination conditions of tamarindus indica Linn seeds with concentrated sulfuric acid treatment and prechilling were researched at different temperatures.The results showed that： the range of the germination temperature wide enough for the seads to germinate at 15~30 ℃.The germination rate was relatively high with concentrated sulfuric acid treatment.With 30 min sulfuric acid treatment,the germination rate was 100 % at 25 ℃;With 15 min sulfuric acid treatment at 25 ℃,30 min or 45 min at 20 ℃,45 min at 15 ℃,the germination rate was also higher,above 90%.Low temperature treatment also played a certain role in promoting germination rate and the germination rate could reach 75 %,but the effect was not as strong as that of the sulfuric acid treatment.
