Effect of different concentrations of IBA on rooting capacity of hardwood cuttings of Populus spp.
The Populus spp. lower ends were soaked in 100,200,300 400,500 mg/L IAA solutions for 15 and 30 minutes to study the effects of IAA on poplar hardwood curlings under different rooting concentration and time. Then the soaked hardwood cuttings were planted and observed. The rooting rates of different mass concentration, different cutting time were compared. The remits show the most suitable concentration and soaking tune for the cutting propagation were solution 200 mg/L and 15 minutes.
