ASPECTS REGARDING VARIETY/ROOTSTOCK RELATIONSHIP IN SOME SPECIES OF FRUIT SPECIES

Abstract

Obtaining large and quality productions requires, in addition to agrotechnical measures, the establishment of the most appropriate symbiosis between grafts (varieties) and rootstocks. This variety/rootstock union particularly influences tree growth, production and quality. Knowing the growth of the root system has an important role in choosing the system of use and tillage, in choosing the land.   The varieties of nectarine on the frank peach rootstock had different vigor, vigor represented by the height, the diameter of the crown, respectively a lower vigor was recorded in the Marina variety, the other varieties being noted with much greater vigor. Compatibility between nectarine varieties and rootstocks was very good, with no split at the grafting point. Deeply developed roots were found in Costin, Tina and Romamer 2 nectarine varieties. Varieties from the pear species namely Williams red, Clapp's Favorite and Daciana showed average vigor and very good rooting - the same varieties together with the Williams white variety.
