摘要
以2种重瓣欧丁香'丰年'和'红翡翠'为材料,根据以往单一因素扦插试验结果,采用正交试验,研究激素种类、浓度及处理时间的不同水平和处理组合条件下对扦插成活率的影响,筛选出适合2种重瓣欧丁香的扦插繁殖方案,为重瓣欧丁香的扦插繁殖与大量生产提供参考依据。结果表明,选用5 cm沙+5 cm草炭土+10 cm原土为基质,使用1000 ppm GGR速蘸20 s,是‘丰年’和‘红翡翠’的最佳扦插方法,成活率分别为79.67%和87.33%。极差分析发现激素种类是影响2种重瓣欧丁香扦插成活率的主要因素。
Using two double-petaled Syrian lilac varieties,‘Fengnian’and‘Hongfeicui’,as materials,and based on previous results from single-factor cutting experiments,an orthogonal test was conducted to investigate the impact of different levels and combinations of hormone types,concentrations,and treatment durations on cutting survival rates.The aim was to identify suitable propagation methods for the two double-petaled Syrian lilac varieties,providing a reference for their cutting propagation and mass production.The results indicated that using a substrate composed of 5 cm of sand,5 cm of peat moss,and 10 cm of native soil,combined with a quick dip in 1000 ppm GGR for 20 seconds,was the optimal cutting method for both‘Fengnian’and‘Hongfeicui’,with survival rates of 79.67%and 87.33%,respectively.Range analysis revealed that the type of hormone was the primary factor affecting the cutting survival rates of both double-petaled Syrian lilac varieties.
