Effect of pre-plant soaking of corms in bio- regulators on corms and cormels Producation in gladiolus (Gladiolus grandiflorus L.) Cv. Rani

Abstract

The present experiment entitled “Effect of pre-plant soaking of corms in bio- regulators on corms and cormels production 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 BA @ 50 ppm was found effective for maximum corms yield (4.27 t/ha). The maximum cormels yield (2.13 t/ha) was found in pre-plant soaking of corms in bio- regulator of thiourea @ 3%. While maximum corm average weight (47.91 g) and diameter of largest corm (5.76 cm) was found in pre-plant soaking of corms in bio- regulator of GA3 @ 150 ppm.
