Effect of IBA on Rooting of Hardwood Cuttings of Various Peach Genotypes

An investigation was conducted in the experimental plot of nursery of Department of Horticulture, Khalsa College, Amritsar during 2018-2019 consisting of hardwood cuttings of 20 cm length and 1.2cm diameter with 5-6 buds prepared from the dormant twigs of the 7-8 years old of Pratap, Florda Prince and Shan-i-Punjab peach cultivars in the second fortnight of November. The basal portion of the cuttings was dipped in different doses of IBA (1000, 1500, 2000, 2500 and 3000 ppm) and control were evaluated. On the basis of data recorded on rooting parameters after 45 days of planting, it was concluded that rooting parameters like root length, root thickness, length of main root, number of roots per cutting and root weight were found maximum in Shan-i-Punjab when treated with IBA 3000ppm. It was concluded that IBA at 3000 ppm was found to be the best treatment for propagation of peach through hardwood cuttings.
