Effect of auxin and media for rooting of different fruit crop cuttings: A review

Abstract

This review includes information on the impact of growth media and auxin concentration on the potential of fruit cuttings to root and shoot. Auxin, a kind of plant hormone, is essential to the rooting process of fruit cuttings and is required for successful propagation. When applied to the basal end of a cutting, auxin particularly Indole butyric acid (IBA) and Naphthalene acetic acid (NAA), increases root and shoot initiation, as well as growth initiation, by stimulating cell elongation, differentiation, and the initiation of adventitious roots. The choice of growing media has a considerable influence on the rooting success of fruit cuttings, influencing their establishment and growth. Different growth mediums, such as perlite, cocopeat, peatmoss, sand, and vermiculite have been evaluated for their effectiveness in promoting root development and rooting characteristics such as root initiation, root length, and overall rooting efficiency, as well as shooting characteristics such as shoot height, shoot diameter, fresh and dry weight of the shoot in fruit cuttings. Water retention capacity, aeration, nutrient availability, pH level, and microbial activity all affect the appropriateness of growth substrate for rooting. This review advances the understanding of the elements that influence the effective rooting and shooting characteristics of fruit cuttings, as well as providing significant insights for improving fruit crop propagation procedures.
