RESEARCHES ON INCREASING THE PROPAGATION YIELD OF VEGETATIVE ROOTSTOCK FOR CHERRY ‘IP-C7’
Journal Title: FRUIT GROWING RESEARCH - Year 2018, Vol 0, Issue
Abstract
‘IP-C7’ is a vegetative cherry rootstock with high resistance to foliar diseases, which adapts easily to different soil types. It is multiplied by softwood cuttings under artificial fog, yielding a multiplication of 85-87%. In the orchard there are induced to grafted varieties, yielding precocity and a high and constant level of production. The studies were carried out at the RIFG Piteşti Mărăcineni, in a mother plantation for cuttings with a density of 5,000 plants/ha in the 3rd year of age and in the green house provided with artificial fog. The objective of this study was to increase the production of shoots and, implicitly, of non-rooted cuttings that can be harvested at the surface unit. In the spring severe pruning was made in the mother plantation, at 3 and 5 buds, and in July from the shoots obtained were made cuttings that were rooted. The following indicators were registered: the length of the shoots, the number of shoots, and the number of cuttings per tree, the rooting percentage of the cuttings, the quality of the root system. Between the two variants of pruning, pruning at 5 buds resulted in an increase of the shoots production of 11.6% and of the non-rooted cuttings of 14.03%. Due to the use of the Radistim V2 biostimulator powder, the rooting percentage increased to 97.9 - 98.3%. Pruning mode in the mother plantation did not significantly influence the rooting percentage of the cuttings. By correlating the production of non-rooted cuttings with the percentage of rooted obtained, in the variant where the pruning was done at 5 buds, a 13.56% increase in the rooted cuttings is obtained compared to the variant in which the pruning was done at 3 buds.
