扦插山茶花不仅可保持亲本的生活力和优良遗传性状,而且方法简便,成活率高。繁殖的后代在第三年就可以见花(图1)。在自然环境下,扦插时间一般在6月。这时空气湿度大,气温在25℃～30℃,有利于插穗产生不定根。插穗应选基部浅赭色、上半部嫩绿色、粗而强健的半木质化当年萌发新枝,这种插条生活力强,断面易愈伤并分化出不定根。插穗应从母本树冠上部新枝丛中或下部萌发的强壮新枝上选取,内膛纤弱枝、下垂枝等萌芽新枝,均不宜采用。
Cutting camellia not only to maintain the viability of the parent and good genetic traits, and the method is simple, high survival rate. Breeding offspring can see flowers in the third year (Figure 1). In the natural environment, the cutting time is generally in June. At this time the air humidity, temperature at 25 ℃ ~ 30 ℃, is conducive to adventitious roots. Cuttings should be selected basal light ocher, the upper part of the tender green, coarse and strong half-lignified new branches that year, this cuttings strong vitality, easy to heal the cross-section and the adventitious root differentiation. Cuttings should be from the top of the parent tree branches of the new branches or lower part of the strong new branches of germination, weak breeders, drooping branches and other sprouting new branches, should not be used.
