Abstract
Present investigations on the “Simultaneous Grafting and Rooting Studies in peach [Prunus persica (L.) Batsch]” was carried out at Fruit Research Farm, Department of Fruit Science, Punjab Agricultural University, Ludhiana during the year 2013-14. 15-20 cm long hardwood cuttings of peach rootstock Flordaguard were taken from 6 year old trees on 5th and 15th January, 2013. These cuttings were tongue grafted with scions of Earli Grande and Shan-i- Punjab having 3-4 buds on them. After grafting, the 3/4 cm basal portion of the grafts were treated with different concentrations of IBA treatments viz. @ 0, 100, 200 (24 hr soaking), 1000, 1500, 2000, 2500 and 3000 ppm (2 minutes dip) and were planted in the field. Sprouting in both the peach cultivars in all the treatments started in the 1st week and completed in the 2nd week of February. Sprouting success was found to be highest in 2000 ppm IBA treatment. The vegetative growth (plant height, stem thickness and number of leaves) of the graft was also found to be maximum in 2000 ppm IBA. Highest mortality of the grafts in all the treatments were recorded in May and after that no/ little mortality was observed. Mortality rate was found to be minimum in higher doses of IBA and maximum in control and lower doses of IBA treatment. The root length and number of roots of both Shani- Punjab and Earli Grande grafts was found to be higher in 2000 ppm IBA treatment. The sprouting success and vegetative growth of all the grafts in all the treatment were better when the cuttings were made on 15th January than on 5th January. The number of salable plants was also observed to be maximum in 2000 ppm IBA treatment in both the cultivars of peach
