刺槐是我国北方主要造林树种之一,近几年选出的干形好、生长快的刺槐优良无性系,增产效益显著。加速优良无性系苗木繁殖,对大幅度地增产,具有重要的经济意义。我们从1977年开始用刺槐优树的嫩茎、叶进行离体培养试验,1978年获得完整植株,并移栽成活。但是快速大量繁殖苗木和大量苗木移栽成活是两个难关。经过几年反复试验,终于突破了这两道难关。在现有设备条件下,每
Robinia pseudoacacia is one of the main afforestation species in northern China. In recent years, Robinia pseudoacacia is selected to be an excellent clone of Robinia pseudoacacia with good dry and fast growth, and its yield increase is remarkable. Acceleration of fine clonal nursery stock breeding, a substantial increase in production, has important economic significance. We started from 1977 with the acacia tree tender stems and leaves of in vitro culture experiments, in 1978 the whole plant was obtained and transplanted alive. However, the rapid population growth of large numbers of seedlings and transplanting seedling survival are two difficulties. After several years of trial and error, finally broke through these two difficulties. Under existing equipment conditions, each
