Abstract

Application of 0.4 % NAA + 2% captan + 2% sucrose-talc to the lower type of sapling origin cuttings of Sapindus mukorossi in monsoon (July-August) resulted in the highest 73.33 per cent ischolar_maining in the species. The pre-sowing seed treatment of soaking seeds of same species in 1 % KNO₃ for 24 brs produced superior germination and seedling growth under nursery condition.

Abstract

The study was conducted to determine the effect of IBA- chemical formulations and cutting types on ischolar_maining behaviour of Erythrina suberosa during monsoon and spring seasons. Cuttings set in spring exhibited overall better performance in all the ischolar_maining characteristics. Application of 0.6% IBA + 1% captan + 2% sucrose- talc significantly maximized sprouting, callusing, ischolar_maining and ischolar_main characteristics (ischolar_main number, ischolar_main length and ischolar_main dry weight). Cuttings of lateral type showed significantly better performance as compared to the terminal and sub- terminal ones. Maximum ischolar_maining (43.33%) and mean ischolar_main dry weight (15.17 mg) were achieved when lateral cuttings were treated with 0.6% IBA + 1% captan + 2% sucrose- talc and planted in spring. The study also revealed that cuttings with higher levels of total phenol, total carbohydrate and C/N ratio and low level of nitrogen performed better.
