Abstract
An investigation was undertaken to analyze the effect of plant growth regulators on growth and flower quality of gladiolus cv.'H.B.Pitt’. In the present study it was found that the maximum height of the plant (59.43 cm), number of leaves (13.9), leaf area (64.8 cm2) were recorded by treatment GA3 200 ppm foliar spray. Lowest plant height was observed in treatment CCC 750 ppm spray. Minimum number of leaves/ plant (10.8) and leaf area (64.8 cm2) were recorded in CCC 250 ppm/plant as foliar spray. In flower quality parameters, maximum number of florets/ spike (13.4), floret length (8.4 cm), length of spike (80.28 cm) and length of rachis (41.50 cm) were recorded with foliar spray of GA3 200 ppm. Maximum weight of floret (10.1 g), diameter of floret (9.5 cm) and girth of spike (2.60 cm) were produced by CCC 750 ppm foliar spray. Minimum number of florets/spike (8.2) and floret length (7.1 cm) were recorded in CCC 250 ppm foliar spray. Lowest weight of florets (8.3 g), diameter of florets (8.2 cm) and girth of spike (1.90 cm) were recorded in GA3 100 ppm spray. Lowest length of spike (74.20 cm) and length of rachis (35.09 cm) were recorded in CCC 750 ppm foliar spray.
Highlights
Gladiolus (Gladiolus grandiflora L.) commonly called sword lilly or corn flag is the seventh most important flowers of the world
An investigation was conducted to find out the effect of foliar application of plant growth regulators on growth and flower quality of gladiolus cv
Growth parameters: From data presented in Table 1 there was significant difference in respect of height of the plant, number of leaves and leaf area as affected by different treatments
Summary
