Abstract
An attempt has been made to study the influence of GA3-pretreated bulbs on growth, flowering and quality of Polianthes tuberosa L. cv. Prajwal, laid on randomized block design in an open field condition. For this purpose, bulbs were dipped in three different concentrations of gibberellic acid (GA3) (0, 50, 100 and 150 ppm), each with 10 replicates. Results indicated that the pretreatment had significantly improved various growth and flowering parameters. Maximum vegetative growth in terms of plant height, number of leaves, leaf length and leaf width was observed in 150 ppm GA3. In addition, the results also showed that the pretreated bulbs at a higher concentration of GA3 had significantly increased spike length, rachis length, number of florets per spike and floret length. Early appearance of initial spike, maximum number of bulbs and maximum durability of spike were also recorded with GA3 150 ppm. GA3 pretreatment also increased chlorophyll content of leaves. Therefore, it was concluded that GA3 at 150 ppm proved to be best concentration in enhancing all the vegetative (plant height, number of leaves and sprouting of bulbs), floral (spike length, number of florets/ spikes, floret length) and bulbous characteristics in tuberose.
