Abstract

An experimental study was conducted at the Horticulture Farm, Department of Horticulture, CCS Haryana Agricultural University,
Hisar, to investigate the Effect of plant growth regulators on corm and cormels production in gladiolus (Gladiolus grandilorus L.)
var. Pusa Shanti. The experiment involved the application of different concentrations of various plant growth regulators, namely
gibberellic acid (GA₃), naphthalene acetic acid (NAA), indole-3-butyric acid (IBA), and chlormequat chloride (CCC), to assess their
effects on corm and cormels production.The results revealed that corm and cormels attributes were found better in treatment
T11(CCC@600ppm) and gave maximum number of corms/plant (3.50), number of cormels/plant (47.33), weight of corms(136.36),
weight of cormels/plant(7.33g) and largest Corm diameter(6.42cm) which can be attributed to more and more translocation of
photosynthates in the corms and cormels due to the dwaring nature of CCC. However, the study faced challenges such as maintaining
uniform environmental conditions and ensuring consistent application of growth regulators across treatments. Despite these
constraints, the study contributes valuable insights into optimizing corm and cormels production in gladiolus and highlights the
potential of CCC as an effective growth regulator for improving planting material yield.
Keywords:Gladiolus, Corm and cormel attributes, Pusa Shanti, Dwaring regulators, GA3, NAA, IBA and CCC
