Effects of GA3 Treatment and Low Temperature Stratification on Seed Germination of Golden Sun Apricot
摘要
Abstract
[Objective] To research the effects of GA3 treatment and low temperature stratification on seed germination of Golden Sun apricot.[Method] With Golden Sun apricot as the test material,the method of GA3 treatment after the first cold stratification treatment was adopted to screen the treatment having the highest germination rate.[Result] Stratification treatment for 20 d with 1 500 and 2 000 mg/L GA3 showed the highest germination rate(60%),which saved 0.17% time compared with the traditional method.Seed soaking for 24 h reached the ideal germination rate.Probability of bacteria growth in seeds removing the shell was greater than that in seeds with shell,especially in summer.Besides,removing the seed shell was not convenient to the operation of production practice.[Conclusion] Treatment of stratification for 20 d with 1 500 mg/L GA3 concentration had the highest seed germination rate,the shortest seedling emergence time,and could screen the high-quality variety.关键词
