Propagation method of epicotyl grafting in walnut (Juglans regia L.) under production condition
S. Gandev, V. Arnaudov
Abstract: The experiment was carried out in 2007-2008 at Fruit-Growing Institute – Plovdiv and on a private fruit tree nursery farm. The elements of the technological process, referring to walnut epicotyl grafting under production conditions, were studied. The following practices were determined: the methods of rootstock production, choosing the cuttings, the grafting methods and the time of grafting, the conditions for callus formation, etc. The results showed that the successfully propagated walnut plants obtained in the different years were from 56.6 % to 63.35 % in average. It was established that the time of grafting exerted an effect on the percentage of survival rate, grafting at the end of March leading to obtaining a higher percentage in comparison with grafting performed at the end of April. The conclusion was drawn that the developed method of walnut epicotyl grafting under production conditions resulted in successful tree propagation and it could be applied in practice.
