红松虽然扦插生根很难,但由于其具有很强的再生机能,12年生红松母树上可培育出7~34条萌芽枝。萌芽枝茎的皮层与韧皮部之间厚壁组织层次少,而且是不连续开放式的,用萌芽枝扦插其生根率比一般枝提高40%。红松出萌芽有2种类型,一种是叶腋的腋芽,一种是针叶束基部的不定芽。不同年龄母树出萌芽枝数量有显著的差异,4年生母树出4.29条、5年生母树出7.6条、12年生母树出31条,同一年龄母树、不同季节处理,其出萌芽枝数量差异不显著,12年生红松从8月至翌年4月分别处理母树,每株母树平均出萌芽枝28~34枝。
Although it is very hard to cut rooting, Korean pine can cultivate 7 ~ 34 sprouting branches because of its strong regenerative function. The thick walled tissue between the cortex and the phloem of sprouting branches and stems is less and is not continuous and open. The rooting rate of germinating branches and shoots is 40% higher than that of normal branches. There are two types of Korean pine buds, one is axillary axils axillary buds, one is the adventitious bud base of the needle. There were significant differences in the number of germinating buds among different ages. There were 4.29 births in 4-year-old trees, 7.6 in 5-year-old trees, 31 in 12-year-old trees and in the same age. The difference was not significant. The 12-year-old Pinus koraiensis plants were treated from August to April the following year, respectively. The average number of germination shoots per plant was 28 to 34.
