    Effect of different rootstocks and varying grafting heights on bud take success and scion growth of Peach (Prunus persica (L). Batsch) Cv. Early White Giant
    (G.B. Pant University of Agriculture and Technology, Pantnagar - 263145 (Uttarakhand), 2004-07) Mer, Rakesh; Nautiyal, M.C.
    The present investigation was carried out at Experimental Block of Department of Horticulture, GBPUA&T, Hill Campus, Ranichauri, Tehri Garhwal (Uttaranchal), during December, 2002 to September, 2003.The experiment was arranged in Factorial Randomized Block Design with 2 factors, nine treatment combinations and four replications. The observations in respect of bud take success and scion growth of peach cv. Early White Giant in response to different rootstocks (peach, plum and apricot) and grafting heights (10, 20, and 30 cm) were recorded. Findings of the present investigation revealed that peach rootstock gave the highest grafting success (79.27 %), girth of scion (2.28 cm), stock girth (3.22cm), canopy spread (154.60 cm2), and resulted into the earliest sprouting (106.70 days) and least wind damage (10.3 %). The maximum length of sprout (37.13 cm), girth of stock (3.22cm), leaf area (1193 cm2), number of leaves (65.25) was recorded with the scion woods grafted on apricot rootstock. The grafting at the lowest height (10 cm) resulted into the earliest sprouting (106.70 %), highest grafting success (79.97 %) and no wind damage. The grafting at 20 cm height however, resulted in maximum girth of scion (2.20 cm), number of nodes (30.27), number of branches (2.70) and saleable plant (72.64 %), whereas highest wind damage (18.63 %), minimum grafting success (66.68 %) and delayed sprouting (116.50 days) were recorded with the scions grafted at 30 cm grafting height in all the three rootstocks. On the basis of results obtained from the present studies it may be concluded that out of three rootstocks (peach, plum, apricot) and three grafting heights (10 cm, 20 cm, and 30 cm), scion of peach cv. „Early White Giant‟ grafted on peach rootstock at a height of 20 cm showed the best results in terms of grafting success and vigour of grafted plants.
