Abstract:
An investigation was carried out to study the effect of gamma rays on growth parameters of bougainvillea varieties in vM₁ generation. The experiment was laid out in Factorial Completely Randomized Design with four replications with two factors viz., Factor A consist of six levels of gamma rays’ treatments i.e., control (No irradiation), 0.25 kR, 0.75 kR, 1.25 kR, 1.75 kR and 2.0 kR. Factor B consist of three varieties i.e., Shubhra (White colour flowers), Partha (Pink colour flowers) and Lady Mary Baring (Orange colour flowers). The irradiation treatment of gamma rays to cuttings of different varieties showed reduction in growth parameters like sprouting and survival percentage, plant height, branches per plant, length of main branch and length of sub-branch. The findings also showed that gradual reduction in values of growth parameters with each increased gamma-irradiation dose.
