摘要: 利用0.4% 2,3,5-氯化三苯基四氮唑染色测定种子活力,研究广东、广西、海南三地栽培益智(Alpinia oxyphylla)种子的贮藏特性与萌发特性。结果表明,低温保湿条件有利于益智种子贮存,短期贮存可达150 d。益智种子发芽时间较短,发芽相对集中的最适条件是温度30 ℃、500 mg·L-1 GA3浸泡24 h;三个种源地的种子发芽率为88%~90%,不同种源地之间的种子萌发率没有显著差异。

Abstract: Alpinia oxyphylla was one of the four famous south medicines in China.Its seeds were the recalcitrant seeds, which could not be preserved for long and has low germination rate. This study was to research preservation and germination traits of A. oxyphylla seed from Guangdong, Guangxi and Hainan. The results showed that through 0.4% TCC water bath dyeing the low temperature moisturizing conditions conducive to the storage of A. oxyphylla seeds. A. oxyphylla in the low temperature storage conditions under short-term storage of up to 150 d for a long time. the germination rate was 88%(Guangdong Sanling Mountain production A. oxyphylla), 88%(Guangxi Yulin production A. oxyphylla), and 90% (Hainan Wuzhishan Mountain production A. oxyphylla), respectively, when the germination time was shorter, and the seed germination relative concentrations were about 30 ℃, and soaked by GA3 500 mg·L-1 for 12 h. There was no significant difference in seed germination between the seeds from three provenances.

Key words: Alpinia oxyphylla, recalcitrant seed, preservation, germination
