tailieunhanh - Effect of plant growth regulators on flowering and quality of tuberose (Polianthes tuberosa L.)

An experimental study was carried out during kharif season of the year 2008-2009 at the farm of Horticulture Section, College of Agriculture, Nagpur. The experiment was laid out in Randomized Block Design (RBD) with three replications and ten treatments viz. GA3 at 100, 150 and 200 ppm, NAA at 50, 100 and 150 ppm, CCC at 1000, 1500 and 2000 ppm and control (Water spray). The higher concentration of GA3 at 200 ppm attributed superior results regarding earliness in initiation of flower stalk, length of spike and length of rachis. The diameter of spike, length and diameter of fully opened florets, vase life of spike, found to be significantly maximum with CCC at 1500 ppm. | Effect of plant growth regulators on flowering and quality of tuberose (Polianthes tuberosa L.)
