GA_3处理对仙客来种子萌发的影响

Effects of GA_3 on the Seed Germination of Cyclamen Persicum

本实验以哈里奥斯系列‘2010’、‘2015’品种的仙客来种子为材料,研究了GA3处理对仙客来种子萌发的影响。结果表明:不同GA3处理均促进了仙客来种子的萌发,提高了种子的发芽率,但不同品种间对GA3处理的反应不同。在18℃下,‘2015’种子最适处理浓度为10 mg/L,时间为4 h;‘2010’种子GA3处理最适浓度为400 mg/L,最佳时间为2 h。

The treatment of GA3 on the effect of seed ‘2010＇ ,‘2015＇ was studied. The results showed that germination of Cyclamen Persicum with Halios seeds the treatments of GA3 could enhance the germination percentage of cyclamen seeds, however, the difference between varieties was significant. The best GA3 treat- ment for ‘2015’ was 10 mg/L for 4 h, while it was 400 mg/L for 2 h for‘2010＇.
