Abstract

An experiment was conducted at Horticulture Research Farm, Department of Horticulture, Institute of Agricultural Sciences, Banaras Hindu University, Varanasi, during the year of 2008-09 to study the effect of kinetin on growth and flowering attributes in gladiolus cultivars. Treatment consisted of kinetin at 50 ppm, 100 ppm, 150 ppm and 200 ppm along with control on 5 cultivars of gladiolus viz.,Archana, Gunjan, J.V. Gold, Sabnum and Snow Princes. Experiment was laid out in a randomized block design and replicated thrice. The results revealed that, maximum length of leaf was recorded with kinetin at 150 ppm followed by kinetin 200 ppm with cv. Gunjan whereas width of longest leaf were noted in cv. Snow princes with kinetin concentrations at 200 and 100 ppm respectively. However, maximum number of leaves/plant was registered with cv. Gunjan at 200 ppm kinetin followed by J.V. Gold at 150 ppm respectively. Among flowering parameters early spike emergence and length of spike were noticed with cv. Sabnumwhen kinetin was spread at higher concentration 200 ppm. In general higher size of first floret was recorded with cv. J.V. Gold at 50 ppm kinetin whereas higher size of fifth floret was recorded with cv. J.V. Gold at 100 ppm. Kinetin at 200 ppm exerted maximum length of spike in cv. Sabnum at 200 ppm kinetin concentration, whereas maximum number of florets/spike was also recorded with cv. Sabnum when kinetin applied at 100 ppm.
