Techniques of Quickly Breaking Seed Dormancy of Tilia amurensis
This paper proposed an orthogonal design L27(313) with four factors(seeds shucked off pericarp, dipped in water, GA3 treatment, 6-BA treatment and stratification)and three levels based on the dormancy of Tilia amurensis seed. The optimal way for quikly breaking seed dormancy was obtained. That was: 1)shucking off the pericarp; 2)scalding seeds for 2s with 100°C boiling water, then soaking in room temperature water for 24h; 3)soaking in 100 mg•L-1 GA3 and 6-BA solution, respectively for 24h; 4)stratification in varying temperature (10-15°C)for 5d, then in low temperature(0-5°C)for 15d. The germination rate of T. amurensis seed could get to 70.2% by above treatment and germination time was shortened to 30 days which was greatly improved compared to previous study.
