嫁接技术作为马尾松无性繁殖的主要手段,在无性系种子园、收集区、采穗圃的建设中已被广泛应用。马尾松嫩枝嫁接,以当年生嫩梢为接穗,砧木为三年生幼龄植株。嫁接之后的穗、砧接合部,从机械结合开始,经接面愈合,到输导组织沟通,最后来自不同母体的两部分组织,形成一个具同步代谢机能的个体。这一过程长达1—2个月之久。这期间正是接后 As the main means of clonal propagation of Pinus massoniana, grafting technology has been widely used in the construction of clonal seed orchard, collection area and sprouting garden. Masson pine shoots grafted to the current year shoot for the scion, rootstock for three-year-old young plants. After grafting, spike, anvil junction, starting from the mechanical combination, the junction healing, to guide the organization to communicate, and finally from two different parts of the parent organization to form an individual with synchronous metabolic function. This process takes 1-2 months. During this period it is picked up
