Title: Effects of plant growth regulators on growth and flowering of tuberose (Polianthes tuberosa L.) cv. single
Abstract: A field experiment was conducted to study the effect of plant growth regulators on growth and yield of tuberose (Polianthes tuberosa L.). Treatments of the experiment were as control (No plant growth regulators), NAA 100 ppm, NAA 200 ppm, NAA 300 ppm, NAA 400 ppm, GA3 100 ppm, GA3 200 ppm, GA3 300 ppm, GA3 400 ppm, 4-CPA 100 ppm, 4-CPA 200 ppm, 4-CPA 300 ppm and 4-CPA 400 ppm. Different concentration of growth regulators showed significant variation on most of the parameters. Tallest tuberose plant (68.9 cm), longest length of rachis (21.9 cm), highest number of floret/spike (41.2), highest diameter of spike (1.1 cm), maximum weight of single spike (40.1 g) and highest number of spikes per hectare (3.9 lac) were obtained from GA3 at 300 ppm.
Key Words: Polianthes tuberosa, GA3, NAA and CPA
