IBA对野生蔬菜少花龙葵插条生根的影响

Effects of IBA on Cutting Propagation for Wild Vegetable Solanum photeinocarpum

摘要:

在室内水培条件下, 研究了吲哚丁酸(IBA)、插条类型及插条留叶方式对野生蔬菜少花龙葵(Solanum photeinocarpum)插条生根的影响。结果表明, 5～35 mg L-1 IBA处理的少花龙葵半叶嫩枝插条生根率均为100%, 以20 mg L-1 IBA处理的平均生根数最多。促进少花龙葵半叶硬枝插条生根的IBA浓度为15～35 mg L-1，其中以25 mg L-1 IBA的效果最好。少花龙葵嫩枝和硬枝插条分别在20与25 mg L-1 IBA处理下，均以半叶插条的生根效果最好、缺叶插条的生根效果最差，全叶插条的生根效果居中。

Abstract:

The effects of IBA and different cutting types, retaining leaves ways on cutting propagation of wild vegetable Solanum photeinocarpum cultured in water were studied. The results showed that the rooting from shoot with half leaf was 100% treated with 5～35 mg L-1 IBA, but the average of rooting was the highest treated with 20 mg L-1 IBA. The rooting from hardwoods with half leaf could be promoted treated with 15～35 mg L-1 IBA, which it had the best effect treated with 35 mg L-1 IBA. The softwoods and hardwoods treated with 20 and 25 mg L-1 IBA, respectively, the rooting effects was in order of segments with half leaf > whole leaf > without leaf.
