摘要

决明子是具较高医疗养生价值的中草药之一,属于硬实种子,因发芽率低导致其产量也较低。本文利用温水和不同浓度的浓硫酸浸种处理对种皮进行软化,发芽后检测决明子的发芽势、发芽率、叶绿素含量、游离脯氨酸含量等指标。结果表明:决明子在80%浓硫酸中浸种20 min或60℃温水浸种2 h处理下,发芽率均达95%以上,并可明显的促进幼苗的初期生长。
        Cassia obtusifolia is one of the Chinese herbal medicines with high value of medical health. The seed of C. obtusifolia is belonging to hard seeds, which results in the lower germination rate while the low yield. Warm water and different concentrated H_2SO_4 were used to soften seed-coat; and the indexes, such as its seeds' germination potential, germination rate, chlorophyll content, free proline content, etc. were measured after the seeds germinating. The results showed that the seed germination rate was up to 95% under the soaking treatment of 80% H_2SO_4 with 20 min or 60 ℃ water with 2 h, and it could obviously promote the initial growth of seedlings.
