INTENSIVE CHERRY ORCHARDS ON THE DWARFING "G.M." ROOTSTOCKS: TRAINING METHODS AND FRUITING PERFORMANCES

Ph. Druart
Cherry orchards to diversify the cultures and as financial income is now recovering the interest of the arboriculturists. The recent releases of dwarfing rootstocks, new varieties more precocious and more fruitful, and the adoption of hight-density plantation systems gave a new attractive opportunity of development. Achievement of the researches developed at the Research Station on fruit and vegetables at Gembloux (Tréfois, 1985) with the selection of 3 dwarfing rootstocks Damil (P. dawyckensis "GM 61"), Camil (P. canescens "GM 79") and Inmil (P. incisa x serrula "GM 9") probably contributed to switch on the nurserymen feeling.

New training forms only workable with growth control by the use of dwarfing rootstocks require further investigations to clearly define the culture conditions and the limitations of their application, to point out the positive and negative aspects as a function of the actual renewing and extension of the varieties assortment.

By the following lecture, the results of our investigations pointing out the interferences between the performances of the rootstock, the variety and the planting system that later on affect the fruiting and has to be taken into account before establishing new orchard.
