Quality of Flower and Bulb in Tuberose under Saline Condition

Abstract

A pot experiment was conducted in the horticultural research farm and laboratories of Bangabandhu Sheikh Mujibur Rahman Agricultural University, Gazipur, Bangladesh during the period from 12 April 2014 to 23 March 2015. In this experiment, salinity treatments with the irrigation water of EC values of 0, 2, 4, 6, 8 and 10 dS/m were imposed to two cultivars of tuberose viz. C 1 = single and C 2 = double. The experiment was carried out in a completely randomized design with five replications. Results revealed that tuberose was sensitive to soil salinity. Almost all the studied parameters of tuberose in both cultivars were unfavorably affected by salinity. Considering the length and diameter of spike, number of spikes per plant, number of florets per spike, vase life, number of large sized underground bulbs and weight of bulb; both cultivars performed better in controlled condition (0 dS/m). Although, these parameters were unaffected by salinity up to 4 dS/m, these got hampered from 6 dS/m and onwards. Both the single and double cultivars were adversely affected by the salinity of soil, but single cultivar was proven more sensitive to soil salinity than double cultivar.
