摘要：In order to study the effect of concentration and time of EMS solution on the emergence and performance of agricultural characters of Cyperus esculentus L., Jinong oil 6 was used as the experimental material, and different concentration (0.5%, 0.7%, 0.9%) and different treatment time (6h, 12h, 24h) were set to treat the seeds of Cyperus esculentus L.. The results showed that the seedling emergence rate, 100 seed weight and seed volume had different performance under different solution concentration and time treatment, and there was strong correlation between them. It was preliminarily considered that the higher solution concentration and time treatment had greater influence on the performance of agricultural characteristics of Cyperus esculentus L., and the combination of 0.9% solution concentration and 6h time was the best condition for EMS induction , tiller number, plant height, yield and other agronomic characters are the most best.
