Effect of 1H-indole-3-butanoic acid on rooting of hardwood cuttings of apple rootstocks at Kirtipur
1997
Ranjit, M. | Manandhar, R.
Treatment of hardwood cuttings with different concentrations of 1H-indole-3-butanoic acid (IBA) indicate that IBA at 50 mg/l resulted in optimum rooting percentage (62.02) whereas at 100 mg/l it resulted in optimum number of roots per rooted cutting (2.40) and longest root (3.70 cm). Among the rootstocks tried, Malus prunifolia had the highest rooting percentage of 63.0 percent followed by M25 (43.5 percent), MM 106 (38.0 percent) and MM 109 (35.3 percent). The numbers of roots per rooted cutting for the four cultivars are 3.90, 1.05, 1.03 and 0.75 while the average lengths of roots are 8.44, 0.41, 0.61 and 0.13 cms respectively.
