以3年生玉兰Magnolia denudata和望春玉兰M.biondii为砧木,于春季运用贴接、切接、腹接技术对景宁玉兰M.sinostellata进行嫁接繁殖,105 d后统计成活率与接穗生长长度。结果显示,贴接的接穗成活率最高,显著高于切接与腹接(p<0.05),最高可达95%;腹接的成活率最低,以望春玉兰为砧木时仅为20%;以玉兰为砧木的成活率都高于以望春玉兰为砧木的成活率(P<0.05),且接穗的生长速度快,采用贴接时最长可达57.6 cm。实验表明,景宁玉兰春季嫁接宜选择玉兰为砧木,并采用贴接法进行嫁接。
Magnolia denudata and M. biondii were used as rootstocks in the experiment. The M. sinostellata was grafted and propagated in spring with the method of affixing, incising and abdomen in spring. The survival rate and scion length were counted after 105 days. The results showed that the attachment scion had the highest survival rate, which was significantly higher than that of the cut and the abdomen (p <0.05), the highest was 95%. The survival rate of the abdomen was the lowest. Only 20% The survival rate of Magnolia as rootstock was higher than that of Magnolia officinalis as rootstock (P <0.05), and the growth rate of scion was fast, with the longest time of 57.6 cm. Experiments show that, Jingning Magnolia spring grafting should choose Magnolia rootstocks, and the use of adhesion method for grafting.
