短枝插穗是指用针叶束芽发育的枝条作插穗。在朝鲜水原,短枝扦插是一个有希望的用于松类树种的无性繁殖方法。该方法有两个优点:从一个优选单株上可获得大量的扦插材料,而且比一般枝条扦插容易生根。影响扦插生根的主要因素是与原株年龄有关的幼年性。即使扦插最难生根的松树,它们的下胚轴扦插也易生根。可是,3龄以上的松树,在扦插生根能力上表现出很快的下降趋势。相反,从9—12年生树上采集的短枝插穗可达60%的生根程度。一、实验方法及树种在3月中旬(早春)将一株松树的主梢顶芽和侧枝顶芽在芽下1cm 处剪掉。这样可 Spur cuttings are shoots that grow with needles and buds for cuttings. In Suwon, the short cuttings are a promising asexual reproduction method for pine tree species. This method has two advantages: a large amount of cuttings can be obtained from one preferred individual plant, and roots are easier to root than the usual cuttings. The main factors that influence cutting rooting are the juvenility related to the original plant age. Even cuttings are the most difficult to root pine, their hypocotyl cuttings are also easy to root. However, pine trees above the third instar showed a very fast downward trend in cuttage rooting ability. In contrast, spikelets harvested from 9-12 year-old trees can reach 60% of rooting. First, the experimental methods and tree species in mid-March (early spring) will be a main tip of the pine shoots and lateral branches of the bud at the bud 1cm cut off. That’s it
