Abstract
The present experiment entitled “Effect of pre-plant soaking of corms in bio- regulators on growth, flowering, yield and quality in gladiolus (Gladiolus grandiflorus L.) cv. Rani.” was carried out at the Jambuvadi Farm, Department of Horticulture, J. A.U., Junagadh (Gujarat) during 2019 to 2020. The results of the study indicated that, the pre-plant soaking of corms in bio- regulator GA3 (150 ppm) was found effective for earlier sprouting (6.90 days), maximum plant height (78.74 cm) and number of leaves (13.62). Regarding flowering characters, the GA3 150 ppm responded best especially in commercial traits like spike length (86.82 cm), rachis length (40.30 cm), number of floret/spike (10.63), diameter of 2nd floret (13.09 cm) and duration of flowering (22.34 days).
