摘要：为研究藏茴香种子萌发特性及影响种子萌发的限制因子,提高藏茴香种子发芽率。本研究对藏茴香种子进行低温沙藏,用不同浓度赤霉素溶液浸种,测定沙藏前后种子胚的占比和发芽指标。结果显示,藏茴香种子胚发育时期多处于点状胚时期,胚未发育成熟,种皮对其萌发不造成障碍;不同浓度的赤霉素对藏茴香种子萌发没有促进作用,相反会抑制种子发芽;低温沙藏处理效果最好,种子发芽率、发芽势均显著高于未处理(ck),其发芽率达34.67%,发芽势达8.00%。藏茴香种子胚未发育成熟,低温沙藏能促进胚的生长;赤霉素无法提高种子发芽率;种皮对其萌发不造成透性障碍,种子休眠类型为深度复杂形态生理休眠(MPD),破除藏茴香种子休眠的有效方法是低温沙藏。
To study the seed germination characteristics of Carum carvi L.and the limiting factors affecting the seed germination,and improve the seed germination rate of Carum carvi L..the seeds of Carum carvi L.were stored in sand at low temperature,and then soaked in gibberellin solution of different concentrations.The percentage of seed embryos and germination indexes were determined before and after sand storage.The results showed that the embryo development stage of seeds of Carum carvi L.was mostly in punctate embryo stage,the embryo was not mature,and the seed coat did not cause any obstacle to its germination;Gibberellin at different concentrations did not promote the germination of seeds,but inhibited the germination of seeds;The effect of low temperature sand storage was the best,the germination rate and germination potential of seeds were significantly higher than that of untreated(ck),the germination rate reached 34.67%,and the germination potential reached 8.00%.The embryo of Carum carvi L.seeds was not mature,low temperature sand storage could promote the growth of embryo;Gibberellin could not improve seed germination rate;The seed coat did not cause permeability barrier to its germination,and the seed dormancy type was deep complex physiological dormancy(MPD).The effective way to break the dormancy of seeds of Carum carvi L.was low temperature sand storage.
