- 摘要:
- 以云南不同品种玛咖种子为试材，采用不同温度对玛咖种子进行处理，分析玛咖种子发芽特性，旨在提高玛咖种子的发芽率。结果表明：15~25℃温度范围内，发芽势、发芽指数、鲜重、干重均随温度提高而提高。不同温度条件下，玛咖种子的发芽率均大于90%，且发芽率随着温度的升高而降低。综合考虑玛咖发芽各项指标，玛咖种子发芽的最适宜温度为25℃。另外，除了干鲜重，黄色玛咖种子发芽率等各项指标均大于黑色玛咖种子。
- Abstract:
- Maca seeds were used as materials，and treated with different temperature，the characterization of germination of Maca was analyzed to improve its germination.The results showed that the temperature among 15-25℃，germination potential，fresh weight and dry weight increased with the temperature increasing.Under the condition of different temperature，the germination rate of Maca were greater than 90%.Considering Maca germination indicators，the optimum temperature for Maca seed germination was 25℃.Germination index of Maca seeds were greater than those of black Maca seeds except fresh and dry weight.
