Standardization of grafting method and time in kiwifruit under temperate conditions of Kashmir

Abstract

The present studies entitled “Standardization of grafting method and time in kiwifruit under temperate conditions of Kashmir” was carried out in the experimental farm, Division of Fruit Science during 2017 and 2018. The experiment was laid out in a Completely Randomized block Design with three replications. In this experiment, three methods of grafting (cleft, tongue and whip) were performed on three different dates (3rdweek of February, 1st week of March and 3rd week of March) with Hayward/Tomuri grafted on 2 years old seedling rootstock under field conditions. The results indicated that leaf width(8.57cm) were significantly better with cleft grafting. Leaf area (94.45 cm2) was recorded highest in tongue grafting and specific leaf area(127.63cm2) was recorded highest with whip grafting. Leaf area (91.90 cm2) and Leaf width(8.54cm) was found highest during 3rd week of March and specific leaf area(143.82cm2/g) with 3rd week of February. Cleft grafting performed during 3rd week of March with Hayward resulted in the highest value of leaf chlorophyll(2.23mg/g). The interaction between method and type of scion was found significant for different parameters under study. From this experiment it can be concluded that among different methods, time and scion type used, cleft grafting performed during 3rd week of February with Hayward cultivar significantly influenced specific leaf area.
