Effect of Bulb Size on Growth and Development of Tuberose

Abstract

Studies on effects of bulb size on growth and development of tuberose (Polianthes tuberosa L.) were carried out, using bulbs of 1.1-2.0, 2.1 – 3.0 and 3.1– 4.0 cm in diameter. Results showed that plants grown from bigger bulb size performed better vegetative growth than those grown from smaller bulbs, recorded by means of canopy height, number of leaf per plant, leaf length and new bulb production. As for reproductive growth, it was found that the plants grown from bulbs having diameter less than 2 cm failed to flower, while those grown from bigger bulbs gave one inflorescence per plant. Days to flower were not significantly different whereas flower quality was found better in the plants grown from bigger bulbs.
