THE INFLUENCE OF ISOLATING MEANS ON THE SURVIVAL AND DEVELOPMENT OF DECIDUOUS WOODY PLANTS CULTIVARS GRAFTS
Abstract
Using the example of three decorative forms, with different regenerative potential, the influence of five isolating substances on the grafts survival was studied. It has been established that decorative forms with a high regeneration potential (Salix caprea ‘Pendula’ and Caragana arborescens ‘Lorbergii’), the substance used to isolate the site of grafting does not have a significant effect on survival. At the same time, in plants with a low regeneration potential (Acer platanoides ‘Globosum’), the high survival rate of grafts is provided by creating a sealed isolation of the site of grafting.
When grafting Salix caprea ‘Pendula’ to isolate the place of grafting it is recommended to use garden putty with the addition of Kornevin (5.6 mg IBA per 1 g of mixture), at which the survival rate reaches 100%; Caragana arborescens ‘Lorbergii’ – medical paraffin, PVC insulating tape and a mixture of ozocerite and paraffin (2:1 v/v) (90.0% suvirval at all means), Acer platanoides ‘Globosum’ – medical paraffin and a mixture of ozocerite and paraffin that provide survival rate of 62.5% and 75.0% respectively.
