INFLUENCE OF ROOTING MEDIA AND ANDOLE BUTYRIC ACID (IBA) ON ROOTING ABILITY OF BUXUSSEMPERVIRENS L. CUTTINGS

Abstract

Lath house trial was laid out at Dept. of Horticulture and Landscape, College of Agriculture, University of Anbar at duration from 15 – 3 – 2016 up to 15-9-2016. The experiment included effect of rooting media viz., Building sand, peatmoss and perlites and concentrations of IBA viz., 0,1500 and 3000 mg l-1. Thus, treat ments were designed under factorial arrangement using RCBD with three replicates. Each experimental unit contained 14 cuttings. Means were compared using L.S.D to extract the significant and differences (p ≤ 0.05). Cuttings that rooted in peatmoss were supervisor on other treatments in all root traits as rooting % of 87.27%, root no. of 11.33 root cutting-1, fresh weight of 0.868 gm and dry weight of 0.222 gm, respectively. Consequently, this positive effect was reflected on vegetative growth traits viz., leaf no. of 27.0 leaf cuttings -1, plant height of 14.47 cm, fresh weight of 3.61 gm and dry weight of 0.914 gm, respectively. Cuttings treated with 3000 mg l-1 were significantly differed in root traits as rooting % of 86.34%, root no. of 12.10 root cuttings -1, fresh weight of 1.171 gm and dry weight traits were improved as treated with 3000 mg l-1 like leaf no of 30.7 leaf cuttings-1, plant height of 15.08 cm, fresh weight of 3.47 and dry might of 1.023 gm. Cutting grown in combination of peatmoss X 3000 mg l-1 were significantly improved that their rooting % was of 90.5 % root no. of 14.60 root cuttings-1, fresh weight of 1.383 and dry weight 0.317 gm. While vegetative traits were of 36.6 leaves per cuttings, 18.63 cm of plant height, 4.64 gm of fresh weight and 1.93 gm of dry weight. Therefore, it could be derived that peatmoss and treated with IBA were effective to improve root traits of this plant species. Hence, it could be recommended to use peatmoss to produce seedlings from this specie
