REACTION OF SOME ROOTSTOCKS FOR PLUMS TO SOIL AND CLIMATIC CONDITIONS OF TROYAN

Due to the specific soil and climatic conditions of the Troyan region, the most common rootstock for plum is ‘Yellow Myrobalan’. During the last five years, with a view to the production intensification, more moderately and poorly growing rootstocks have been studied at IMSA in Troyan, such as ‘Wavit’, ‘Wangenheims’, ‘SJ A’, ‘Fereley’, ‘Brompton’, ‘GF 655-2’, in combination with the cultivars ‘Stanley’, ‘Čačanska Lepotica’, ‘Hanita’, ‘Jojo’, and ‘Tegera’. The poorest growth in the cultivars ‘Stanley’ and ‘Čačanska Lepotica’ was induced by ‘Wangenheims’ and ‘SJ A’, in ‘Hanita’ by ‘Wangenheims’ and ‘GF655-2’; and in ‘Jojo’ by ‘Brompton’ and ‘Wavit’. The trees of all cultivars engrafted on the ‘Fereley’ rootstock had the most vigorous growth, but formed many shoots.
It was found that the ‘SJ A’ rootstock, with 22% to 44% dead trees depending on the cultivar, was not suitable for the specific clay-loam soils of the region, frequently subjected to overwetting.
