景天科多肉植物的侧芽萌发试验

Succulent Plants of Crassulaceae: Germination of Lateral Bud

为促进景天科多肉植物侧芽的萌发,笔者于2015—2016年对‘虹之玉’、‘姬胧月’等6种多肉植物开展试验,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。

The paper aims to promote the germination of lateral buds of succulent plants of Crassulaceous.We carried out the experiments on Sedum rubrotinctum,Graptopetalum‘Bronze’and other 4 cultivars of Crassulaceous succulents in Wuhan during 2015-2016,and to promote the germination of lateral buds by means of stem base picking leaves and spraying 6-BA.The results showed that:lateral buds could be greatly promoted as follows:removing 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 was 5 mL,which could effectively promote the lateral bud germination of Crassulaceous succulent plants.
