摘要
为了探讨火麻种子发芽的最佳温度,就不同温度条件对火麻种子发芽的影响进行了研究,结果表明:火麻种子发芽的温度范围为5～35℃,在20℃条件下种子发芽率达到最大为95%,在25℃条件下种子发芽势和发芽指数达到最大,分别为92.3%和40.3%,然后随着温度的升高或降低发芽率下降显著;经方差分析在20℃和25℃条件下种子的发芽势之间、发芽率之间差异均不显著,而发芽指数之间差异极显著。火麻种子发芽的最佳温度是25℃,最低温度是5℃,最高温度是35℃。
The effects of temperature on the germination of fire hemp were investigated.Fire hemp seeds germinated from the minimum temperature 5℃ to the maximum temperature 35℃.The maximum germination percentage was 95% at 20℃,But the optimum germination occurred at 25℃,with the germination energy and germination index reaches its maximum,92.3% and 40.3%,respectively.The germination rate declined significantly as temperature increases or decreases from the optimum temperature 25℃.using variance analysis,seed germination rate differences were not significant,germination index were significant between 20℃ and 25℃.
