ABSTRACT
An experiment was conducted to determine the effect of plant growth regulators on corm characteristics and post harvest performance of gladiolus cv. American Beauty at the Agriculture and Forestry University, Rampur, Chitwan during September, 2013 to March, 2014. The study consisted of 10 treatments laid out in a randomized complete block design (RCBD) and replicated three times. Three levels of NAA (50 ppm, 100 ppm and 150 ppm), three levels of GA3 (50 ppm, 100 ppm and 150 ppm), three levels of Kinetin (50 ppm, 100 ppm and 150 ppm) and control (no PGR application) were applied as foliar sprays at 30 and 45 Days after planting. GA3 shows significantly promising results on corm, cormels characteristics, vase life and post harvest behavior of gladiolus spike. GA3 @ 150 ppm resulted maximum corm weight and corm diameter whereas both GA3 @ 100 ppm and NAA @ 150 ppm recorded significantly high number of cormels/plants. GA3 @150 ppm and NAA @ 150 ppm showed significantly maximum corm weight and days to the fist basal floret withering. However, the vase life of gladiolus spike was superior with GA3 @ 150 ppm.
