以5种天然汁代替激素2,4-D、kt对芦笋愈伤组织增殖效应进行研究,结果表明:所用5种天然汁以玉米汁的效应最佳,最佳浓度为5.OmL·L~-1,其次是椰乳汁,最佳浓度为7.5mL·L~-1。当两者混合使用时效应更佳,并且在芦笋愈伤组织增殖效应方面能代替2,4-D、kt以及笔者所在研究室长期使用的激素组合2,4-D2mg·L~-1+kt 1 mg·L~-1。
The effects of 5 kinds of natural juice instead of hormones 2,4-D and kt on the callus proliferation of asparagus were studied. The results showed that the best effect of the 5 natural juices was corn juice, the optimum concentration was 5.OmL·L ~ -1, followed by coconut milk, the best concentration of 7.5mL · L ~ -1. When mixed with the two, the effect is better, and in the asparagus callus proliferation effect can replace the 2,4-D, kt and the author’s laboratory long-term use of hormone combinations 2,4-D2mg · L ~ -1 + kt 1 mg · L ~ -1.
