摘要
2013年7月试验比较了4个木犀(Osmanthus fragrans)品种‘圆叶四季桂’(O.fragrans‘Yuanyesijigui’)、‘天女散花’(O.fragrans‘Tiannusanhua’)、‘金秋早’(O.fragrans‘Jinqiuzao’)和‘状元红’(O.fragrans‘Zhuangyuanhong’)的耐修剪能力,2014年7月研究多效唑和矮壮素对‘天女散花’和‘圆叶四季桂’的矮化效应。结果表明,‘圆叶四季桂’和‘天女散花’的耐修剪能力较强;多效唑和矮壮素都能抑制所试品种的新梢生长,前者效果强于后者。600 mg/kg和800 mg/kg多效唑处理的‘天女散花’和‘圆叶四季桂’的矮化效果明显,新梢萌发多,株型矮小紧凑。
Experiment was conducted on pruning resistance of Osmanthus fragrans ‘Yuanyesijigui’, O. fragrans ‘Tiannusanhua’, O. fragrans ‘Jinqiuzao’, and O. fragrans ‘Zhuangyuanhong’ in July 2013. In July 2014, another experiment was made on dwarfing capacity of paclobutrazol （PP333） and chlorcholinchlorid （CCC） on O. fragrans ‘Tiannusanhua’ and O. fragrans ‘Yuanyesijigui’. The results demonstrated that O. fragrans ‘Yuanyesijigui’ and O. fragrans ‘Tiannusanhua’ had stronger resistance of pruning. Both PP333 and CCC could inhibit new shoot growth of the tested two cultivars, the former had better effect. O. fragrans ‘Tiannusanhua’ O. fragrans ‘Yuanyesijigui’ treated with 600mg/kg and 800mg/kg of PP333 had the best result of dwarfing with much more new shoot, smaller shape and more tight of the tree.
