黄花丁香引种适应性及扦插育苗技术研究

Study on the Introduction Adaptability and the Cutting Technology of Syringa Pekinensis “Beijing Gold”

通过半致死温度的估算及田间观测后认为,黄花丁香抗寒性低于暴马丁香,但高于紫丁香,在牡丹江局部区域可以引种成活。嫩枝扦插实验表明:200mg/LABT1号处理插穗1小时是较为适合的激素处理方法,黄花丁香嫩枝扦插成活率最高可达89%。

Based on the estimation of semi lethal temperature and field observation,it was considered that the cold resistance of S.pekinensis was lower than that of Syringa,but higher than that of lilac,and it can be introduced to some areas in Mudanjiang.The softwood cutting experiment showed that 200mg/LABT1 treatment for 1 hours was suitable for hormone treatment.The survival rate of S.pekinensis cuttings reached 89%.
