Caracteristicile fitometrice ale structurii plantaţiei superintensive de măr în funcţie de soi şi modul formării coroanei de tip fus zvelt

Abstract

At the varieties Gala Must, Golden Delicios, Idared, grafted on M 9, were studied 4 methods of fusiform crown formation. The phytometric features of crowning plantation structure, especially the productive volume and leaf index, registered siuperior values in the variant with 2 additional provisional main branches and forced horizontalization into free space of the offshoots and vertical, vigorous branches. In this variant the fruit yield in average on 3rd to 5th year from the beginning of crown formation is 134-150 t/ha, beeing greater than the variant control with 20-23 t/ha or with 15-16%.
