摘要
经过2 a多对平欧杂种榛子扦插试验研究的结果表明:(1)400 mg·L-1GGR1号生根粉水溶液浸泡的插穗生根率最高,达65.1%,清水处理的穗条效果最差,生根率为6.7%;(2)一年中插穗在6月、9月扦插效果最好,成活率分别可达58.86%、67.48%;(3)插穗摘除1/3叶片扦插效果最好,生根率达66.7%;(4)母树上部穗条扦插效果最佳,成活率可达66.8%;(5)平欧杂种榛子插穗以皮部生根为主,属于皮部和愈伤组织混合生根型,夏季扦插60 d后成活穗条皮部生根的占84.46%。
In order to get the technologies of establishing scion plucking orchard and cutting seedling propagation skills on Pingou hybrid hazelnut, the data was collected in a trial arranged different treatments for 2. 5 years" time. The results showed that (1) in cuttings, using a treatment of 400 mg ·L^-1 GGR1 root promoting power solution was best, the rooting rate was 65.1%, the clear water treatment effect of cuttings was the worst,and its rooting rate was below 6.7% ; (2)When the cutting time was in June or before October, the survival rate reached the best,namely 58.86% and 67.48% ; (3) Scions with 2/3 leaf blade had the best rooting rate of 66. 7%. (4)The upper branches of cuttings had the highest survival rate of 66. 8% ; (5) The scions rooted from both bark and callus,while 84. 46% of the sions rooted from bark only.
