几种四倍体刺槐新品种及繁殖技术已于1997年从国外引进,并在我国的区域性引种试验中取得显著成绩。嫁接和组培育苗技术都取得成功,组培苗移栽成活率从10％提高到80％以上。目前,已在我国山西、甘肃、宁夏、河南、四川等17个省市开展区域性试验,并在山东省开始生产小批量种苗。 据该项目主持人北京林业大学田砚亭教授介绍,此次引进的四个刺槐品种都是人工诱变的四倍体,其
Several new varieties of tetraploid Robinia pseudoacacia and propagation technology were introduced from abroad in 1997 and achieved remarkable results in the regional introduction test in China. Grafting and tissue culture seedling technology have been successful, transplanting tissue culture survival rate increased from 10% to 80%. At present, we have carried out regional experiments in 17 provinces and cities such as Shanxi, Gansu, Ningxia, Henan and Sichuan in our country and started to produce small-batch seedlings in Shandong Province. According to the project host Professor Tian Yan-ting of Beijing Forestry University, the four varieties of black locust introduced in this time are all tetraploids of artificial mutagenesis.
