The effect on seed germination of Allium mongolicum Regel through the treatments of H2SO4(98%)、PEG-6000(w/w) and GA3 was studied,in order to choose the optimal method of facilitating seed germination.The results showed that:(1) The 5 min soaking time treatments of H2SO4 could enhance the germination of Allium mongolicum seeds and was 2.25 times higher than CK;(2) The concentration of 15%(w/w) PEG for soaking 6h was the optimal group,was 5 times higher than CK;(3)The effect of GA3 treatments on germination w...
