Abstract

Water apple is one of the important fruit crops, but it remains uncultivated in many parts of the world due to less success in seed propagation and unavailability of quality planting material. Hence this study was undertaken to determine the impact of IBA, rooting media, and association between the different parameters on success of air layering in water apple at North Farm, Karunya Institute of Technology and Sciences, Coimbatore (2022–23), with 12 treatments replicated thrice. The experiment was set up using a FRCBD with four distinct concentrations of IBA, viz., 1000 (I1), 2000 (I2), 3000 (I3), and 4000 ppm (I4), and three rooting media i.e. cocopeat (M1), sphagnum moss (M2), and garden soil (M3). According to the analysis of variance, all treatments were found significant for all parameters. Among the treatment interactions, 4000 ppm IBA with sphagnum moss was earliest for the commencement of roots, time taken for layers to separate, root length, diameter and number of roots. Sphagnum moss was found superior for early rooting and root number. According to the results, using IBA and media together will be more effective at encouraging early rooting and getting more number of roots than using either IBA or media alone.

Conclusion

From the above investigation it can be concluded that the rooting and vegetative growth of air layers were all improved by the exogenous application of IBA with rooting media, particularly IBA at 4000 ppm. Sphagnum moss was the most effective rooting media for fastening the rooting in air layers. The treatment combination of 4000 ppm IBA and sphagnum moss was resulted in the best root initiation (100%) of water apple air layers. With this, we can determine the optimum dose and combination (4000 ppm IBA with sphagnum moss) for air layering in water apple to produce high-quality planting materials.
