摘要
以美国红枫‘太阳谷’(Acer rubrum‘Sun Valley’)为试验材料,剪取当年生嫩枝为插穗,插穗分成粗、细2种规格。选取1 000 mg/L和2 000 mg/L ABT 1号生根粉作为生根促进剂,处理时间分别为10,20,30 s。结果表明:2 000 mg/L ABT 1号生根粉处理10 s的粗插穗生根率达到93.8%,平均根长为3.3 cm,平均根数为16.3条;2 000mg/L ABT 1号生根粉处理20 s的细插穗生根率为84.4%,平均根长和平均根数分别为3.4 cm和17.1条,建议使用2 000 mg/L ABT 1号生根粉对粗插穗处理10 s或使用2 000 mg/L ABT 1号生根粉对细插穗处理20 s的方式用于美国红枫"太阳谷"的扦插繁殖。
After the current-year branches( thick and thin) of Acer rubrum‘Sun Valley'taken as cuttings,and 1 000 and2 000 mg/L ABT1 used as root-inducing regulator with 10,20 and 30 s respectively of treating time,the effects of ABT 1on the cutting propagation were studied. The results showed that the rooting rate of the thick cutting dipped in 2 000 mg/L ABT1 for 10 s could reach 93. 8%,with the average root length of 3. 3 cm and root number of 16. 3,and the rooting rate of the thin cutting dipped in 2 000 mg/L ABT1 for 20 s could reach 84. 4%,with the average root length of 3. 4 cm and root number of 17. 1. So it is recommended that as for A. rubrum‘Sun Valley'cutting propagation,using 2 000 mg/L ABT1 to treat thick cuttings for 10 s or 2 000 mg/L ABT1 to treat thin cuttings for 10 s should get a better effect.
