Abstract:
The present study was carried out in open private commercial field in El-Behira Governorate, Egypt (30"54'34, 87"N and 30" 42' 33, 78" E) during the period from 15 February 2013 to 26 April 2013. The study deals with the effect of seven different concentrations of indole-3-butyric acid (IBA) (control zero, 500, 1000, 1500, 2000, 2500 and 3000 ppm) for 12 h and three types of planting media (sand, sand: peat moss 1:1(v/v) and peat moss) on root performance of Jatropha curcas L. and Euphorbia tirucalli cuttings. Data were collected ten weeks after planting the cuttings. Three experiments were conducted where in Experiment 1: Cuttings were taken from two years old of Jatropha curcas L. terminal branches 6-8 cm length treated with IBA at different concentration showed the rooting behavior in the order: 1500 ppm>1000 ppm>3000 ppm>2500 ppm >2000 ppm>500 ppm> control. In case of propagation 1500 ppm IBA treatment was found to be the best (6.8 roots/cutting, 1.32 cm root length, 71.1 rooting percentage, 3.1 g fresh weight, 1.5 leaves/cutting, 2.4 cm length of the longest leaf and 38 days to sprout). In Experiment 2: Cuttings were taken from four years old of Jatropha curcas L. terminal branches 15-17 cm length treated with IBA at different concentration showed the rooting behavior in the order: 2500 ppm >3000 ppm >2000 ppm>1500 ppm>500 ppm>1000 ppm>control. In case of propagation 2500 ppm IBA treatment was found to be the best for (8.3 roots/cutting, 5.6 cm root length, 68.8 rooting percentage, 14.8 g fresh weight, 3.1 leaves/cutting, 4.6 cm length of the longest leaf and 50 days to sprout). In Experiment 3: Cuttings were taken from terminal branches of Euphorbia tirucalli 20-22 cm length treated with IBA at different concentration showed the rooting behavior in the order: 2500 ppm>1500 ppm>2000 ppm>3000 ppm>1000 ppm>500 ppm>control. In case of propagation 2500 ppm IBA treatment was found to be the best for (8.2 roots/cutting, 11.8 cm root length, 73.3 rooting percentage, 5.2 g fresh weight, 7.7 leaves/cutting and 46 days to sprout). The types of planting media treatment showed the rooting behavior in order: Sand>sand: Peat moss 1:1 (v/v)>peat moss for both cuttings of Jatropha curcas and Euphorbia tirucalli in all three experiment.
