Effect of rootstocks on the growth and yielding of sharka-resistant ‘Jojo’ plum trees under organic orchard conditions
Journal Title: Journal of Research and Applications in Agricultural Engineering (ISSN 1642-686X) - Year 2018, Vol 63, Issue 3
Abstract
The experiment was established in the spring of 2005 at the Experimental Ecological Orchard in Nowy Dwór-Parcela (cen-tral Poland). The aim was to assess tree growth vigour and yielding as well as fruit quality of the cultivar ‘Jojo’ grafted onto Myrobalan and ‘Wangenheim Prune’ seedlings. Th e trees were maintained in accordance with the principles of or-ganic fruit-growing. The trees grafted onto Myrobalan seedlings grew much more vigorously than those on ‘Wangenheim Prune’ seedlings. On both rootstocks, the trees of the cultivar ‘Jojo’ came into fruiting in the secon d year after planting. In the first years of fruiting, the fruit yields produced by the trees grafted on Myrobalan and ‘Wangenheim Prune’ seedlings did not differ significantly. A significant effect of the rootstock on the yielding of trees was found in the years 2013-2016, i.e. from the ninth year after planting. Higher yields were obtained from the ‘Jojo’ trees grafted onto Myr obalan seedlings. There was no significant effect of the rootstock on fruit weight in any year of the study. Under the organic orchard condi-tions, some of the fruits were affected by the plum fruit moth (Laspeyresia funebrana) and by the brown rot of stone fruits (Monilinia laxa, Monilinia fructigena). The type of rootstock was not found to have an effect on the degree of fruit infesta-tion by pests or infection with diseases.
