Study on Seed Germination of Acacia podalyriifolia

In order to optimize the treatment methods and improve seed germination rate of Acacia podalyriifolia, this research used the methods of sacrification seed coat and soaking in hot water treatments, absolute alcohol treatment, sodium hydroxide solution and concentrated sulfuric acid treatment to study the characteristics of seed germination. The results showed that the germination potential and rate of all treatments were significantly increased, compared with the control(P0.05). The treatment of sacrification seed coat had great effect on A. podalyriifolia seeds germination potential and rate, which were 84.6% and 87.3% respectively. The germination potential and rate treated by 90 ℃ water for 3 min were the highest among all different temperature treatments, and it were 58.0% and 61.0% respectively. The seed-soaking treatments with absolute alcohol and sodium hydroxide solution have significantly effected on the germination potential and rate of A. podalyriifolia. But with the extension of processing time, germination potential and rate had no significant changes. The average germination rate of seed-soaking treated by concentrated sulfuric acid in 5 minutes was the highest, up to 64.0%. Generally, due to such factors as efficiency and security, treatments by 90 ℃ water for 3 minutes and absolute alcohol for 90 min were better than other methods in production.
