Abstract: In this paper,soaking treatment with non-hormone and hormone of Lavandula angustifolia ‘French Blue’ seeds and their effect on seeds germination and seedling growth whether a more effective role in promoting was expored. Using 4 kinds of non-hormonal method, seeds soaked in cold water for 24h, 30℃ constant temperature water for 24h, acetic acid for 30 min, 1% NaOH for 15 min respectively, and 200,300,400,500,600mg/L of GA3 soaking treatment, without soaking seeds as control, observed the seeds germination rate and seedling growth.Then by comparing data of two groups, the best non-hormonal treatment as soaking pretreatment, combined with the optimal hormone concentration soaking without pretreatment, to select the most suitable seeds germination soaking method.The results showed that seeds germination and seedlings growth significantly promoted using cold water for 24h(P<0.05), inhibited using acetic acid and 1% NaOH, promoted significantly using GA3(P<0.01).The best GA3 concentration was 600 mg/L,but we found no significant effection on seed germination and seedling growth with cold water pretreatment before GA3 soaking seeds.So soaking can soften the seed coats to promote seeds germination and seedlings growth, but cold water soaking is not necessary before GA3 soaking.
