Effects of salicylic acid on germination of seed and growth of seedling in pea

The seeds of pea(No.1 Qinghe)were soaked with different concentration of salicylic acid(SA)for 12 hours,and the rate of seeds germination,the content of soluble-sugar and protein,and the growth of seeding were measured.The results indicated that the rate of seeds germination was not inhibited obviously,the contents of soluble-sugar and protein were increased and the index of seed germination and growth of seeding were enhanced after the seeds were treated at 10 mg/L and 50 mg/L of SA respecitively,but the physyological indexes were decreased and the growth of seeding was inhibited.
