摘要
青海云杉(Picea crassifolia)系扦插难生根性树种,为解决扦插枝条生根难、成活率不高的问题,采用不同生长调节剂对青海云杉1年生休眠枝条处理后进行扦插试验,结果表明,处理8(50 mg.kg-1的GGR6号浸泡2 h)为最佳组合,1年生青海云杉扦插苗愈伤组织形成时间、成活率、顶梢生长量、顶梢粗度等方面与其他处理差异显著,成活率为81.33%,顶梢生长量3.46 cm,顶梢粗度为1.47 cm。
Picea crassifolia is difficult to root species. To solve the problems for cutting root for difficult rooting plant and lower survival rate, after using different growth regulators on dormant branches of 1-year-old Picea crassifolia, cutting experiments were conducted. Result shows that： treatment 8 （ solution of 50 mg· kg^-1 GGR No. 6 for 2 h） is the optimal combination;formation time for callus of cutting seedlings, survival rate, growth and diameter of top shoot on 1-year-old Picea crassifolia are significant with that on other treatments; the survival rate, growth and diameter of top shoot is 81.33% ,3. 46cm, 1.47cm, respectively by using treatment 8.
