EFFECT OF MATURITY AND SIZE OF STEM CUTTING ON ROOTING SUCCESS AND GROWTH IN DRAGON FRUIT (Pages : 10 - 16)
M. AHSAN-ULLAH, M.M. ROB, U. HABIBA, M.M. HASAN AND S.R. SAHAA study was carried out at BAU Germplasm Center, Department of Horticulture, Bangladesh Agricultural University, Mymensingh during 24 March, 2011 to 24 April, 2012 to investigate the effect of maturity and size of stem cutting on rooting success, days to root initiation, shoot number and plant height in two Dragon fruit varieties. All the treatments showed significant effect on the parameters studied. Shorter time was needed for first root initiation (27.42 days) which also produced taller plant (65.25 cm), primary (4.19 days), secondary (1.98), and tertiary (0.225) shoots number, and percent rooting success (100) by BAU Dragon fal-1. Matured cutting required comparatively shorter time for first root initiation (25.92 days), and produced the highest plant height (66.16 cm), primary (4.03), secondary (1.94), and tertiary (0.22) shoots number, and percent rooting success (100). In respect of stem cutting size, lowest time was required for first root initiation (26.32 days) with the tallest plant height (83.93 cm), primary (4.81), secondary (2.29), and tertiary (0.29) shoots number and percent rooting success (100) by the large cutting. The combined effect of three factors had also significant effect on the studied parameters. Minimum time was required for first root initiation (23.30 days) with the maximum plant height (89.54 cm), primary (5.26), secondary (2.5), and tertiary (0.33) shoots number by BAU Dragon fal-1 with large sized matured cutting.Download
