Potential Role of Bio-Stimulants in Administering Floral Characters of Asiatic Lily cv. Indian Summerset

Abstract

An experiment was conducted at Horticulture Research Farm, Department of Horticulture, Sam Higginbottom University of Agriculture, Technology and Sciences, Prayagraj during 2021-22 and 2022-23. The experiment consisted of thirteen treatments viz T1-   control, T2- 10 ppm triacontanol, T3-15 ppm triacontanol, T4-20 ppm triacontanol, T5- 25 ppm triacontanol, T6- 5 ppm brassinolide, T7-10 ppm brassinolide, T8-15 ppm brassinolide, T9-20 ppm brassinolide, T10-100 ppm nitrobenzene, T11- 200 ppm nitrobenzene, T12-300 ppm nitrobenzene, T13- 400 ppm nitrobenzene which were arranged in Randomized Block Design with three replications.  Foliar application of bio-stimulants was done twice at fifteen days interval. Analysis of the data indicated that treatment T9 (brassinolide @ 20 ppm) reported to be best for parameters namely days taken for first flower opening from bud emergence (33.2 days), pedicel length (9.2 cm), number of flowers/stalk (3.8), flower length (15.0 cm), flower diameter (16.4 cm) and flower yield (9.0 flower stalks/plot and 33.3 flower stalks/m2).
