Effect of Different Temperature Treatments on Germination Dynamic of Festuca arundinacea Sehreb

Germination index of Festuca arundinacea Sehreb.as experiment material was studied with different temperature levels.The results showed that germination index had different dynamic variation with day rising,germination index raised in 25 ℃,35 ℃ soaking and 18 ℃,25 ℃ culture treatment,which is beneficial to seed germination,germination rate and germination energy had significant link(r0.989 6),and culture temperature is key control factor which had significant effect on germination index.
