三七不同种子贮藏方法对出苗及种苗质量的影响

摘要

Four methods of seed storage were investigated .Four treatments were allocated into A ,B ,C and D .A was planting immediately and with seed vessel;B was planting immediately and without seed vessel ;C was placement of seeds at 4℃ to keep fresh for 49 days (seeds were in the valve bag );D was placement of seeds in the wet mortar at room temperature to keep for 49 days .The emerging rate ,seedling rate ,the aver-age seedling weight and seedling quality were tested .The results showed that different seed storage methods had significant influence on the e-merging rate ,seedling rate and the average seedling weight .The best storage method was B .%研究了三七种子不同处理对出苗率、成苗率、平均苗重及第一、二级种苗比例的影响。试验设置4个处理，即A：种子采后带果皮立即播种；B：种子采后洗去果皮立即播种；C：种子采后洗去果皮置于4℃保鲜49d （种子装于自封袋内）后播种；D：种子采后洗去果皮湿沙室温层积49d后播种。结果显示：三七不同种子贮藏方法对其出苗率、成苗率及平均苗重的影响均达到极显著水平。较理想的方法是种子采收后洗去果皮立即播种。
