摘要
马尾松诱根嫁接,将接穗接在砧木根颈处,接后培土,诱导接穗生根,形成新植株。本试验嫁接成活率与成活接株生根率均达70％以上。该嫁接方法的优点是:接部愈合与接株生长良好,并可降低树冠层,扩大结实面;同时接穗形成自生根,防止后期不亲和。这是马尾松无性系良种繁育的一项新技术,可供生产应用。
The grafting technique of inducing-root from scion is reported in this paper. After grafting, we put some soil around the base of the seedling stock. Then the induced scion starts to root and grow up. Both the grafting survival and its rooting rate surpassed 70 %. There are many merits in using this technique, i.e. the wound between scion and stock healed completely and the grafted tree grew well, the position of the crown is lower than that of the tree before and the scope of fruitness expands. The root could be induced from the base of the scion and there is no affinity between scion and stock in the later stage of its growth. This is a new technique in clone breeding of masson pine and it could be used in practice.
