Abstract:
An experiment was conducted in the year 2022-23 to study the effect of different concentrations of IBA and time of air layering (months) on rooting parameters of Soursop at Karunya Institute of Technology and Sciences, Coimbatore, Tamil Nadu. As the soursop seeds are poor in germination, propagation by air layering is carried out in this study. The results designate that IBA @ 4000 ppm was proven to be most effective for better rooting parameters (days required for initial root appearance, success percentage of rooted air layers, number of primary roots and secondary roots and length of primary roots). Compared to other treatments, air-layering done during the first two weeks of August, treated with 4000 ppm IBA, and using sphagnum moss as a growing medium has been found to be much more effective.
