PERFORMANCE OF THE "GM" ROOTSTOCKS IN HIGH-DENSITY SWEET CHERRY ORCHARDS |
| Author: | P. Druart |
| Abstract:
High density sweet cherry orchards have expanded due to the recent choice of dwarfing rootstocks, research on orchard management, and new self-fertile varieties with denser flowering habit and large fruit size. Among the dwarfing rootstocks, Damil (GM 61/1), Camil (GM 79) and Inmil (GM 9) were selected at our Research Station from a population of botanical Prunus (Tréfois, 1985). Damil has been grafted with more than 140 different varieties. Since 1985, comparisons have been made of two high density orchard systems: "GM" spindle and hedge. In addition, 52 of these varieties were grafted onto Camil and 75 grafted onto Inmil; all were planted only in the hedge system. The results for tree vigour, flowering potential and fruit set are presented. | |
