摘要: 摘 要:为促进景天科多肉植物侧芽的萌发,于2015—2016年对虹之玉、姬胧月等6种多肉开展试验,通过茎基摘叶、喷施6-BA等方式促进侧芽的萌发。结果表明,摘除植株茎部2/3的叶片,并向裸露的茎部喷施浓度为1000 mg/L的6-BA溶液,每周喷施1次,共喷施5次,每次每条茎的喷施量为5 mL,即可有效促进景天科多肉植物茎上侧芽的萌发。【结论】:根茎喷施赤霉素可有效促进景天科多肉植物的侧芽萌发。

Abstract: Abstract: The study aims to promote the germination of lateral buds of crassulaceous succulent plants. The experiments were conducted on Sedum rubrotinctum、Graptopetalum ‘Bronze’ and other 4 cultivars of crassulaceous succulents in Wuhan during 2015-2016. The results showed that: lateral buds could be greatly promoted as follows: removing the 2/3 of leaves from the stems of the plants, spraying 6-BA solution with a concentration of 1000 mg/L to the exposed stems once a week for 5 weeks, the spraying amount of each stem is 5 mL. 【CONCLUSION】:The stem spraying of 6-BA can effectively promote the lateral bud germination of the crassulaceous succulent plants.
