Abstract

The success in propagation is known to be influenced by the method, time and environment conditions to which the plants are subjected to grow before and after propagation. So there is urgent need to standardize the environment and time for clonal multiplication of walnut in order to ensure supply of quality plant material for expansion of area, there by facilitating manifold increase in production and productivity of superior nuts and meeting the international standards of quality characters of nut and kernel. Since, no systematic work has been carried out to see the combined influence of the rootstock planting time, scion type and time of grafting. Therefore, the present investigation entitled “Exploring combinations of rootstock planting time, scion type and time of grafting on grafting success of walnut plants” was carried out in the Experimental Farm, of Division of Fruit Science, SKUAST-K- Shalimar during the years 2017 and 2018. The experiment was laid out in a Randomized Com

Conclusion

The present investigation entitled “Vegetative propagation of walnuts under polyhouse conditions” revealed that among the different timings of rootstock planting, rootstocks planted during 2nd fortnight of November proved significantly better in comparison to other timings. Scion type having middle portion of current season growth with 3-5 buds grafted during 3rd week of February on the rootstock which was planted during 2nd fortnight of November took minimum days to bud swell and bud bursting and had higher graft success per cent, more number of leaves, higher leaf area and shoot length and greater final height of grafted plants. Thus, rootstock planting during 2nd fortnight of November and grafted during 3rd week of February with scion type having middle portion of current season growth with 3-5 buds should be practiced for large scale multiplication of walnuts under polyhouse conditions.
