| 摘 要： | 沼泽小叶桦属于嫩枝扦插难生根树种,采用ABT生根粉可有效促进其生根。研究表明,ABT生根粉浓度与浸泡时间的最佳组合为ABT生根粉50mg/L,浸泡15min,沼泽小叶桦生根率达到51%。浓度与浸泡时间有一定的互补作用,即高浓度、短时间与低浓度、较长时间2种组合处理有相似的促根作用。

| Abstract: | Betula microphylla var.paludosa is hard to root by softwood cutting,and ABT powder is useful for rootage.The results showed that 15 min for soaking and 50 mg/L of concentration for ABT were a proper combination for rooting,which made Betula microphylla var.paludosa achieve 51% of rooting rate.There was a complemented relationship between ABT concentration and soaking time,i.e.higher ABT concentration with shorter soaking time and lower ABT concentration with longer soaking time can play similar function in promoting rootage. |
