dc.description.abstractThe present investigations entitled “Effect of growth regulators and chemicals on plant growth and cormels production of gladiolus” were undertaken in the experimental field area of Floriculture and Landscaping, Punjab Agricultural University, Ludhiana, during 2017- 2018. The cormels of two varieties of gladiolus namely Punjab Glad-1 and Punjab Pink Elegance were treated with GA3 (150 and 200 ppm), BA (100 and 125 ppm), SA (100 and 150 ppm), Thiourea (1000 and 1500 ppm), KNO3 (1.5 and 2.5 %), Ethrel (250 ppm) and combinations of Thiourea and KNO3 as pre planting dip treatment for 12 hours. The analysis of variance was conducted as per Randomized Block Design. The minimum time to sprouting was recorded with GA3 200 ppm in Punjab Glad-1 (9.57 days) and Punjab Pink Elegance (10.44 days). The maximum sprouting percentage was recorded with GA3 200 ppm in Punjab Glad-1 (97.94 %) and Punjab Pink Elegance (98.81 %). In Punjab Glad-1, maximum plant height (30.72 cm), leaf length (29.18 cm), leaf width (1.05 cm), leaf area (22.98 cm2) and number of leaves per plant (4.48) was recorded under GA3 200 ppm. Similarly, in Punjab Pink Elegance maximum plant height (31.74 cm), leaf length (30.33 cm), leaf width (0.97 cm), leaf area (22.27 cm2) and number of leaves per plant (5.00). The maximum size of cormel was recorded in variety Punjab Glad-1 (2.10 cm) and increase in size was 4.20 times of the initial cormel size when treated with GA3 200 ppm. In variety Punjab Pink Elegance, maximum cormel size was recorded with GA3 200 ppm (2.12 cm) with 4.23 times increase in size of cormel. The maximum cormel weight was recorded with GA3 200 ppm (9.38 g) in Punjab Glad-1 and (9.38 g) in Punjab Pink Elegance.en_US
