Abstract:
The present experiment entitled “Effect of IBA and Saccharides on rooting and growth in stem cuttings of pomegranate (Punica granatum L.) cv. Bhagwa” was carried out during 2019-2020 at Fruit Research Station, Imalia, Department of Horticulture, College of Agriculture, J.N.K.V.V., Jabalpur (M.P.). The present experiment was laid out with seventeen treatments and three replications in Completely Randomized Design (CRD) under polyhouse condition to study the effect of IBA and Saccharides on root and shoot growth parameters and establishment of rooted cuttings. There results revealed that different growth parameters were significantly varied among different treatments. Among the seventeen treatments sucrose @ 5000 ppm (T₄) performed superior in shoot parameters and IBA @ 5000 ppm (T₁₆) performed superior in root parameters. Besides, sucrose @ 5000 ppm recorded maximum sprouting percentage (86.58%), shoot parameters viz., number of shoots (6.33, 6.90, 7.46 and 8.83), number of leaves (26.33, 37.67, 48.67 and 57.33) at 30, 60, 90 and 120 days and length of new shoots (30.60 cm, 37.10 cm and 39.83 cm) at 60, 90 and 120 days. However, IBA @ 5000 ppm recorded maximum number of primary and secondary roots (34.33, 168.33), length of primary and secondary roots (29.50 cm and 9.40 cm), longest root length of primary roots (31.33 cm), success and survival percentage of rooted cutting (76.67% and 70.97%), respectively. Therefore, from the present investigation results found that the cuttings treated with sucrose @ 5000 ppm and IBA @ 5000 ppm gave pronounced effect on shoot and root formation indicating its effectiveness for propagation in pomegranate under polyhouse conditions.
