摘　　要：设置5种浓度(0、50、100、200、300 mg·L-1)ABT溶液和浸泡时间处理藏柏和巨柏插穗开展扦插试验,探讨其对西藏2种柏树插穗生根的影响。通过测定插穗切口愈合率、膨大率、腐烂率和根系发育等指标,应用隶属函数值法综合评价不同处理对藏柏和巨柏插穗生根的影响。结果表明:100 mg·L-1的ABT溶液中浸泡插穗3 h对藏柏和巨柏插穗愈伤组织和根系发育状况最优。Cuttage of Cupressus torulosa and C. gigantea with different concentrations ABT and soak time were implemented, in order to clarify the cuttings rooting capacity of two cpyresses. According to measuring the indexs of the cuttings growth, as callus ratio, swell ratio, rotting ratio, root growth, and so on,the method of subordinative function value was complicated to comprehensive evaluate the the treatment-effectiveness. The results showed that the treatment of cutting soaked in 100 mg·L-1 ABT solution and lasting 3 hours was suitable for cuttings growth of Cupressus torulosa and C. gigantea in Tibet.
