EXPERIENCE WILD APRICOT ARMENIACA MANSHURICA AS ROOTSTOCK FOR APRICOTS IN ECOLOGICAL CONDITIONS OF CZECHOSLOVAKIA
The original area of Armeniaca manshurica (Max) Skvortz. wild Manchurian apricot — is in the north-east Asia, in the region of the Manchurian floristic zone. It is a variable sort — with a number of forms which can be distinguished according to the differences in morphology of their particular organs. The trees, which were used for the experiments in Czechoslovakia — (in the southern and central part of Slovakia), come from: 1) Central China (Peking region),2) Soviet Central Asia (the region of Alma-Ata and Kazachstan). Both types being morphologically clearly different, we distinguished them even by name as: 1) the Peking type and 2) the Tyan-shan type. Both types of wild Manchurian apricot were incorporated into a series of experiments as rootstocks for some cultural varieties of apricots of the middle-European and Chinese assortment. Brief characterization of Armeniaca manshurica as a rootstock for apricots: From a dense and widely spread system of roots there grows a healthy, erected, mechanically very firm stem which appears to be a very solid basis even for a heavy grafted crown. It has a very hard but flexible wood. It is very healthy, resistant against freezing in winter and high temperatures in summer. The leaves showed to be resistant against cockchafers. It grows well together with the grafted cultural varieties of apricots. The best method is to graft higher into the stem. The grafted cultural varieties bear nornmal fruit, in some cases a positive influence on the yield of fruit could be registered. Armeniaca manshurica has the best properties from all the investigated rootstocks of wild apricots, especially in damper and cooler areas.
