为找出最优育种方法,提高发芽率,获取更多优质种苗,从而为漆树种质资源及产业发展提供指导,采用三因素(98%的H_2SO_4、400 mg/L的GA3、砂藏时间)三水平的全因素试验方法,每处理设置单个变量,共计27个处理组合,对不同种源漆树种子萌发条件进行研究。结果表明:A种源漆树种子的最佳萌发条件为,98%的H_2SO_4处理30 min+400 mg/L GA3处理60 min+砂藏30 d;B种源漆树种子萌发率最高的条件为,98%的H2SO4处理30 min+400 mg/L GA3处理60 min+砂藏20 d;C种源漆树种子萌发率最高的条件为,98%的H_2SO_4处理30 min+400 mg/L GA3处理120 min+砂藏20 d。98%的H2SO4处理时间、400 mg/L GA3处理时间、砂藏时间对不同种源的漆树种子发芽率、芽长、芽粗均存在极显著影响。
In order to find out the optimal breeding method, increase germination rate and obtain more high-quality seedlings, three factors (98% H 2 SO 4, 400 mg / L GA 3, sand storage time ) Three levels of all-factor test method, set a single variable for each treatment, a total of 27 combinations of treatment, different seed germination of Laccase conditions. The results showed that the optimum germination conditions of A seed tree were as follows: 98% H 2 SO 4 treatment for 30 min + 400 mg / L GA 3 treatment for 60 min + sand storage for 30 days; H2SO4 treatment for 30 min + 400 mg / L GA3 treatment for 60 min + sand storage for 20 d. The highest seed germination rate of C seed germplasm resources was 98% H 2 SO 4 treatment for 30 min + 400 mg / L GA 3 treatment for 120 min + d. 98% H2SO4 treatment time, 400 mg / L GA3 treatment time and sand storage time had a very significant effect on the germination rate, bud length and bud diameter of the seeds from different provenances.
