Abstract:

An investigation on “Influence of growth regulators on vegetative parameters of Gladiolus cv. Summer Sunshine” was carried out at Department of Floriculture and Landscape Architecture, College of Horticulture, Mudigere (Under University of Agricultural and Horticultural sciences, Shivamogga), during 2016-17. Experiment was conducted by planting the corms which are soaked into different plant growth regulators at different concentration for 24 hr. The treatment comprised of, GA3 (50, 100 and 150 ppm), NAA (50, 100 and 150 ppm), BA (50, 100 and 150 ppm), thiourea (10000, 15000 and 20000 ppm) and control. The results revealed that BA @100 ppm was recorded the maximum number of suckers per plant (4.03) and maximum number of leaves per plant (12.43). Minimum number of suckers (1.00) and leaves (7.09) per plant were recorded by control. Whereas, GA3@ 150 ppm was taken minimum number of days to fifty per cent sprouting (9.07) and control was taken maximum number of days to fifty per cent sprouting (14.13). The maximum plants height (73.52cm), leaf length (63.30 cm), leaf width(5.11 cm), leaf area (2324.02 cm2) and leaf area index (3.87) was recorded from GA3 @ 150 ppm. Whereas, BA @ 100 ppm was recorded minimum plants height (44.66cm), leaf length (36.16cm) and leaf width (3.66cm). Minimum leaf area (1250.62cm2) and leaf area index (2.08) was recorded from control at 60 days after planting. Theses result emphasizes the significant difference among the different growth regulators with respect to vegetative parameters of gladiolus cv. Summer Sunshine, which impact on flower yield and quality.


Keywords: GA3, BA, NAA, Thiourea and corm soaking.
