Abstract

The effect of bulb size and GA3 on vegetative and floral characters of tuberose (Polianthes tuberosa L.) cvs. Prajwal and Calcutta Single was studied. The results revealed that among the two varieties, Prajwal (V1) showed significant increase in growth, flowering, quality and yield attributes, as compared to Calcutta Single (V2). While, in case of bulb size; bulbs having diameter of 2.6–3.5 cm (B2) had significant effect on vegetative growth, quality and quantity production of tuberose spikes, bulbs and bulblets as compared to bulbs having diameter 1.5–2.5 cm (B1). However, GA3 at 100 ppm (G2) also had a striking influence in enhancing the growth, flowering, quality and yield characters over control (G0).
