Abstract
An investigation To Study the Effect of PGR on Rooting of Leaf-bud Cuttings in Assam Lemon (Citrus limon(L) Burm.) was carried out during the year 2018 - 2019in the polyhouse, citrus block, Department of Fruit Science, College of Horticulture and Forestry, Central Agricultural University, Pasighat, Arunachal Pradesh. It is geographically located at 28° 04’ 43” N latitude and 95° 19’ 26” E longitude with an altitude of 153 m above mean sea level.The present investigation was carried out in completely randomized design (CRD) in the raised beds inside the polyhouse and replicated thrice.
The prepared cuttings were treated with different doses of IBA, NAA and their combination in powder form and planted in raised beds in polyhouse.The experiment was laid out in Completely Randomized Design having thirteen treatments i.e. T1 (Control), T2 (1000 ppm IBA), T3 (2000 ppm IBA), T4 (3000 ppm IBA), T5 (4000 ppm IBA), T6 (1000 ppm NAA), T7 (2000 ppm NAA), T8 (3000 ppm NAA), T9 (4000 ppm NAA), T10 (500 ppm IBA + 500 ppm NAA), T11 (1000 ppm IBA + 1000 ppm NAA), T12 (1500 ppm IBA + 1500 ppm NAA), T13 (2000 ppm IBA + 2000 ppm NAA).
From the present study, it can be concluded that the treatment T2 (1000 ppm IBA) was found to be best for rooting of leaf-bud cuttings and survival percentage of Assam lemon (Citrus limon L Burm). Over all, the treatment T2 (1000 ppm IBA) gave the significant response in respect to all the shoot and root parameters during the observation periods i.e., days taken to first shoot initiation, height of first shoot initiation from ground level, number of shoots per plant, length and girth of shoots, number of leaves per shoot, number of roots, length and girth of roots, fresh and dry weight of roots and survival percentage in the foot hills of Arunachal Pradesh.
