在马尾松育种工作中,建立无性系种了园和优树采穗圃,都要求接株能最大幅度地将优树号原来的性能继续稳定、遗传下来,获得具有优树号特性的新的植株。同时,在进行后出鉴定时,才可以精确地鉴别优树号的遗传能力如何。近年来,我们设想采取低部位嫁接、接后培土,从而诱导接穗发根的办法,使接德成为独立的植株,以获得保存母树遗传特性的植株。对此,进行了多次试验。这些试验,都是用一、二年生湿地松作砧木,马尾 In the breeding of Pinus massoniana, the establishment of clonal plantations and spruce tree nurseries, are required to pick the strain can maximize the excellent performance of the original tree number continued to be stable, genetically, access to a tree with excellent characteristics of the new Plant. At the same time, it is only possible to accurately identify the genetic ability of the tree when conducting post-identification. In recent years, we have envisaged a low-grafting approach followed by earth-grafting so as to induce the rooting of the scion and make Jide become an independent plant for the purpose of preserving the genetic characteristics of the mother tree. In this regard, conducted a number of tests. These tests are used one or two years wetland pine stock, cauda equina
