Abstract
The present investigation was carried to study the effect of method and time of grafting on different rootstock to assess graft success and growth in low chill peach cv. Shan- e-Punjab at CCSHAU, Hisar during 2018-19. Three different rootstocks viz., Peach cv. Sharbati seedling and rooted cutting of Plum cv. Kala Amritsari and Green Gage were propagated by three grafting method viz., tongue, wedge and whip on different times viz., 9th and 25th of January in Factorial Randomized Block Design (FRBD) with three replication. Results reveal that earliness in grafting (9th January) had significantly higher graft success and sprouting percentage over 25th January whereas all growth parameter viz., plant height, number of leaves, leaf area, percent increase in scion and rootstock diameter, fresh and dry weight of shoot and root, RWC, leaf nitrogen and potassium content and total chlorophyll content were significantly superior on 25th January.
Among grafting methods, tongue grafting was found superior over wedge and whip grafting for maximum sprouting percentage, graft success, plant height, number of leaves, leaf area, percent increase in scion and rootstock diameter, fresh and dry weight of shoot and root, RWC, leaf NPK content and total chlorophyll content. Similarly, Sharbati seedling performed better as compared to Kala Amritsari and Green Gage cutting for maximum sprouting, graft success, plant height, number of leaves, leaf area, percent increase in scion and rootstock, fresh and dry weight of shoot and root, relative water content, leaf nitrogen, phosphorus potassium content and total chlorophyll content.
