甜菊种子小,又无休眠期,种子寿命与温湿度有密切关系。成熟的种子得到适当的温度、水分即可发芽,如在高温多湿的广州,种子仅能保存2个月。在辽阳,种子保存18个月,发芽率仅有6.5％。在年降水量450毫米,年平均气温7.9℃的建平县,种子保存14个月,发芽率仅下降11.1％,说明在种子贮存过程中,适宜的温湿度能延长甜菊种子的寿命。为延长甜菊种子的寿命,增加保存年限,我们在贮存条 Stevia seed is small, and no dormant period, seed life and temperature and humidity are closely related. Mature seeds get the right temperature, water can germinate, such as high temperature and humidity in Guangzhou, the seeds can only be stored for 2 months. In Liaoyang, the seeds were preserved for 18 months and the germination rate was only 6.5%. In Jianping County, with an annual precipitation of 450 mm and an average annual temperature of 7.9 ℃, the seed was stored for 14 months and the germination rate was only decreased by 11.1%. This shows that proper temperature and humidity can prolong the life of stevia seeds during seed storage. In order to extend the life of stevia seeds and increase the shelf life, we are in the storage bar
