Abstract

greenhouse-lrgIn order to study on the effects of rooting bed, IBA concentrations and bottom heat on rooting and some characteristics of plane tree cuttings, an experiment was conducted as factorial in RCBD (4 rep). The treatments were 3 different rooting bed: sand, perlite, and sand + perlite, (1+1 by volume), with 4 levels of IBA concentrations (0 ppm, 1000 ppm, 2500 ppm, and 5000 ppm) and with or without bottom heat, during the primary to 4 months, survival rate, dry weight of roots, root length, number and dry weight of leaves were measured. The results showed that the highest survival rate (76.47%) and dry weight of leaf (4.38g) obtained in combination treatment sand + perlite bed, without auxin treatment and bottom heat system, the highest dry weight of root (5g) obtained in combination treatment sand bed, 2500ppm IBA and without bottom heat system, the highest number of leaf (9.6 leaf) obtained in combination treatment sand + perlite bed, 2500ppm and bottom heat system.
