Features of grafting decorative forms of the genus Larix Mill

Abstract

The influence of the age of the scion and the insulating material on the survival rate and morphometric para- meters of annual grafted plants is shown, using the example of Larix kaempferi ‘Blue Dwarf’. It has been established that when grafting decorative forms of the genus Larix Mill. the most effective is the use of annual shoots as a scion with isolation of the grafting site with an elastic polyethylene film, which ensures 100 % survival and optimal development of the crown.The use of 2-year-old shoots as a scion with a shortened by 2/3 annual growth does not lead to a significant change in sur- vival rate and a decrease in the height and diameter of annual grafted plants, but it allows to increase the density of the crown. The use of these shoots as a graft can be recommended for propagation of garden forms, the grafting of which is complicated due to thin annual shoots.
