Effect of bulb Size on Growth and Development of <I>Globba rosea</I> Gagnep.

Abstract

Studies on growth and development of Globba rosea Gagnep. were carried out. The plants were grown from bulbils of 3 different sizes, i.e. 0.21 - 0.25, 0.26 – 0.35 and 0.36 – 0.4 cm in diameter. It was found that the plants grown from bigger bulbils gave better vegetative growth, considering from plant height, number of leaf per plant, leaf length and new bulb production. As for reproductive growth, it revealed that the plants from smallest size of bulbils failed to flower. The inflorescences produced from flowering plants had no flower and only bulbils were found in the bract axils of those inflorescence.
