摘 要: | 目的]明确不同条件下五月艾种子的发芽特性。方法]通过发芽试验,考察了不同发芽床、温度、光照、pH、水势、播深、不同预处理条件、不同贮藏方式和贮藏时间等因素对发芽的影响。结果]在不同的发芽床中,五月艾种子在纸上(TP)处理的发芽率最高,为94.32%;在20~35℃条件下发芽率较高,其中在25℃下,发芽势和发芽率分别达到67.50%和93.25%;光照对发芽无明显影响;种子在pH值为4~10时,发芽率较高,为80.21%~92.98%;最适萌发水势为0~-0.2Mpa,发芽率为88.25%~93.02%;最适播深为0~1cm,出苗率大于92.53%;赤霉素处理有利于种子的萌发,在冰箱中保存,可以较长时间保持种子的活力。结论]该试验对不同条件下五月艾种子萌发特性进行了系统的研究,明确了其种子发芽的适宜条件,为今后进一步开展五月艾的引种、栽培提供了参考。

Abstract: | Objective]The aim was to investigate the germination characteristics of Artemisia indica Willd.seeds cultured in different conditions.Method]The Germination tests were used to evaluate the effects of different germinating beds,temperature,illumination,pH value,water potential,planting depth,pretreatment,storage methods and storage time on germination of Artemisia indica Willd.seeds.Result]The results showed that the seeds on paper (TP) with the highest germination rates,which was 94.32%.The suitable range of germination temperature of the seeds was from 20 ℃ to 35 ℃,and the germinability and germination rate was 67.50% and 93.25% respectively cultured at 25 ℃.Illumination had no effect on the germination of the seeds.The germination rate was 80.21% to 92.98% with pH of 4-10.The most suitable solution potential was 0~-0.2 Mpa,with the germination rate of 88.25%-93.02%,and the most suitable soil depth was from 0 to 1 cm,with the germination rate of 92.53%.Gibberellin are conducive to the germination of the seeds and the vitality of seeds can be maintained for a longer time storage in refrigerator.Conclusion] The germination characteristics of Artemisia indica Willd.Seeds were studied,and the optimum culture condition were obtained which would provide reference for the further introduction and cultivation of Artemisia indica willd. |
