大叶相思引进我省后,表现良好,深受群众欢迎。为了开辟快速繁殖苗木的途径,我们于1979年底开始研究用组织培养法繁殖大叶相思,同年底获得完整的试管苗。以后进行了培养基的筛选,移植圃基质选择,造林后生长情况调查等。目前,我们已可用组织培养法进行大叶相思苗木的批量生产。一、材料和方法 1—7年生大叶相思的当年枝条茎段,未成熟的幼叶(叶状柄)作组织培养的材料。 Acacia leaf after the introduction of our province, performed well, welcomed by the masses. In order to open up avenues for the rapid propagation of seedlings, we began to study the propagation of Acacia macrostachys with tissue culture at the end of 1979, and obtained the complete in vitro plantlets by the same year. After the screening of medium, transplant nursery substrate selection, after the growth of afforestation survey. At present, we have available tissue culture method for mass production of Acacia macrostachya seedlings. First, materials and methods 1-7 year-old Acacia elegans shoots, immature young leaves (leaf-shaped handle) for tissue culture materials.
