Abstract:
A field experiment was conducted to study the efficacy of plant bio-regulators on flowering and bulb production of Asiatic Lilium hybrid cv. Tresor during the year 2017-18. The trial was conducted in a randomized block design with ten treatments in four replications. The treatments comprised of foliar application of GA₃ at 50ppm alone and in combination with BA at 50 ppm, GA₃ at 75ppm with BA at 75 ppm, Chlormequat chloride alone at 75ppm, 100ppm, 125 ppm concentration and in combination with GA₃ at 50ppm and a control (water spray). The result revealed that application of 50 ppm GA₃ significantly increased the plant height (72.32 cm), number of leaves per plant (81.58) & leaf length (11.57 cm), advanced the days to bud appearance (19.37 days), bud break (45.75 days) & first flowering (46.12 days) whereas basal stem diameter (2.1 cm) was significantly higher with application of 125 ppm Chlormequat chloride. Application of 125 ppm Chlormequat chloride & 50 ppm GA₃ significantly enhanced the number of flowers per plant (3.66), bloom life of individual flower (7.66 days), bloom life of whole spike (15.24 days) and vase life (14.57 days).
