Preliminary results of substrates study for softwood cutting method of clonal plum rootstocks
Abstract
The aim of the research is the estimation of genetic potential of vegetative prune rootstock rooting (VPK-1, VVA-1, 140-2, OD-2-3) at different substrates by softwood cutting method. The following substrates were used: ‘Chervensky’ soil/pearlite; ‘Chervensky soil’/BIONA-112; ‘Chervensky soil’/AQUASOSB’. In the study the influence of rootstock forms (р<0,05), substrate type (р><0,05), and combined action (р><0,05) of the factors was established on rooting of prune vegetative rootstocks. The optimal substrate for rooting is appeared to be substrate 1 (‘Chervensky’/pearlite). The maximal amount of rooted cuttings of all studied vegetative prune rootstocks was noted on substrate 1. It was established that the best results in rooting was noted for OD-2-3 (56%). >< 0,05), substrate type (р< 0,05), and combined action (р< 0,05) of the factors was established on rooting of prune vegetative rootstocks.
