摘要

以日本落叶松‘蓝矮’为例,研究了接穗年龄和保温材料对一年生嫁接植株成活率和形态参数的影响。已经确定,嫁接时,落叶松属的装饰形式。最有效的是使用一年生枝条作为接穗,用弹性聚乙烯薄膜隔离嫁接部位,这确保了100%的存活率和最佳的树冠发育。将2岁的嫩枝作为接穗,缩短2/3的年生长量,不会导致成活率的显著变化和一年生嫁接植株的高度和直径的降低,但可以增加树冠密度。使用这些芽作为嫁接可以推荐用于园林形式的繁殖,嫁接是复杂的,由于薄的一年生芽。

Features of grafting decorative forms of the genus Larix Mill
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.
