Effect of plant bioregulators on vegetative and floral attributes of gladiolus

Abstract

Two plant growth regulators were applied on to gladiolus cultivars, viz., Jester and Snow Princess. NAA at 100 ppm gave maximum increment in plant height, number of shoots per m2. Application of 100 ppm kinetin had positive influence on panicle emergence, while panicle length and rachis length were better with 100 ppm NAA. A maximum of 19.4 florets per spike in Snow Princess, while longer vase-life (15.76 days) was noted with 100 ppm kinetin.
