Abstract:
The present investigation was carried out to study the Response of gamma irradiation on vegetative parameters of tuberose (Polianthes tuberosa L.) cv. Pearl Double. The results revealed that lowest decline trends were recorded on days to 50% sprouting (74.33, 71.33), sprouting percentage at 30 DAP (21.67, 28.33), plant survival percentage (96.67, 95.00), plant height (cm) at 60 & 90 DAP (35.53, 36.56 & 41.09, 44.30), Leaves/plant at 60 & 90 DAP (24.93, 25.07 & 26.07, 28.40), Leaf length (cm) at 60 & 90 DAP (29.27, 29.22 & 29.30, 29.24) and Leaf width at (cm) 60 & 90 DAP (1.68, 1.72 & 1.69, 1.75) at 2.50 Gy and highest declined trends at 20.0 Gy gamma irradiation in V₁M₁ (1^st year 2017-18) and V₁M₂ (2^nd year 2018-19) generation respectively as compare to control.
