Abstract
The most common and commercial method of propagating litchi is air layering in which wounding the stem and treating with auxin helps in better rooting. Recently some non-auxinic chemicals are being used to synergise the effect of auxins. Therefore, an investigation was carried out to determine the response of different cultivars of litchi to IBA alone and in combination with pHB on different rooting parameters and survival of layers. All the rooting parameters I.e. length of roots, number and weight of roots both fresh and dry and survival of rooted layers were improved significantly with 5000ppm IBA+ 1OOOppm pHB treatment. These traits were however recorded significantly maximum in Rose Scented when compared with other cultlvars.
