Abstract
The present research was carried out to study the effect of growth regulators on growth, flowering and corm production of Gladiolus Gladiolus grandiflorus L. cv. white friendship during 2017 in floriculture yard, Department of Horticulture, Sardar Vallabhbhai Patel University of Agriculture and Technology, Meerut 250110. Four growth regulators viz., GA3, NAA, CCC and MH each at three concentrations in addition to water spray as control comprised thirteen treatments of this experiment. The experiment was laid out in a Randomized Block Design (RBD) with three replication. All the growth and yield parameters were periodicaly observed. The results revealed that the growth regulators application significantly influenced the growth and yield of Gladiolus sp cv. white friendship. The maximum No. of florets/spike, spike length (cm) and flower length (cm) were obtained were obtained with GA3 @100ppm as compared to rest of the treatments. Whereas CCC @500 ppm was found the best interms of corms and cormels production.
