摘要
以黑色玛咖和黄色玛咖的种子为材料,采用不同浓度的赤霉素(0 mg/L、50 mg/L、100 mg/L、200 mg/L、400 mg/L)浸种24 h,测定其种子发芽率、发芽势、根长等指标,比较不同浓度赤霉素对玛咖种子发芽的影响。结果表明,与对照相比,不同浓度赤霉素处理均能提高玛咖种子发芽率、发芽指数、根长等指标,当赤霉素浓度为200 mg/L时,对黄色和黑色玛咖种子发芽效果最佳。不同浓度赤霉素浸种后,黄色玛咖种子萌发的各项指标均大于黑色玛咖种子。
To test the seeds germination rate, germination vigor, the root length and other indexes under the differ-ent concentration of GA3 （0 mg/L, 50 mg/L, 100 mg/L, 200 mg/L, 400 mg/L）, black Maca and yellow Maeaseeds was used as material and soaked for 24 hours. The results showed that compared with the control group, theseed germination rate and root length of Maca was higher with different concentration of GA3 treatments. When theGA3 concentration was 200 mg/L, the effecton black and yellow Maca seeds germination was the best. After soakingwith different concentration of GA3 , the germination indexes of yellow Maca seed were higher than that of blackMaca seeds.
