Effect of IBA and planting containers on shoot and root characters and survival of litchi air-Bayers

摘要

The experiment was conducted on fourteen-year old litchi trees. Layers were treated with three levels of IBA i.e. 0, 500 and 1000 ppm. Rooted layers were planted after 60 days of layering in four types of containers viz., polythene bags, root trainer,nursery bed and plastic pot. Shoot and root growth and survival were recorded after seven months of planting of root layers. IBA at 1000 ppm significantly increased plant height, 1st, 2nd and 3rd order roots/layer, length of longest root, mean root length, mean root thickness, diameter of 1st order root, fresh weight of roots/layer and survival of layers. However, all the concentrations of IBA failed to exert any significant effect on diameter of stem, number of leaves/layer, leaf area and dry weight of roots/layer. Similarly, layers plants in root trainer significantly improved shoots and root characters and survival of layers. Maximum values on various shoot and root parameters and survival were noted in 1000 ppm IBA and root trainer treatment combination.
