Role of Gibberellic Acid in Tuberose Cultivation

Tuberose (Polianthes tuberosa L.) is one of the potentially valuable cut flower and is an important commercial flower of our country. The long flower spikes of tuberose are excellent cut flower and the individual florets are used for making garlands ornaments for bridal make up and for button holes. Due to lack of standard production technology the yield of quality flowers per unit area is low hence growth regulators can play a very important and remarkable role for production of good yield with quality flowers. Soaking of bulbs in GA3 before planting and its foliar application improves the growth and flowering of tuberose it also enhances early flowering and maximum yield of spikes and flowers.
