Effects of different period and cutting ways on the survival of softwood cuttings in Platanus acerifolia

研究了不同时期及剪截方式对二球悬铃木嫩枝扦插成活的影响.结果表明,不同时期对插穗成活率,伸长量,叶片数,平均根数,平均根长的影响差异极显著;而不同剪截方式对插穗成活率,伸长量,叶片数,平均根长的影响差异均不显著,但对平均根数的影响差异极显著.悬铃木嫩枝扦插的最佳时期为5月下旬到6月下旬.

This paper researched the effects of different period and cutting ways on the survival of softwood cuttings in Platanus acerifolia.The results showed that： The effects of different period on the survival rate,elongation,leaves number,average root number,average root length were most significant.The effects of different cutting ways on the survival rate,elongation,leaves number,average root length were not significant.But it had the most significant effect on the average root number.The best cutting period of softwood cutting in Platanusa acerifolia was from late May to late June.
