Abstract:The present investigation entitled title “Influence of Plant growth regulators on Gladiolus (
Gladiolus grandiflorus L.) cv. Traderhorn under Bundelkhand Region” was carried at the Experimental, Organic Research farm Kargunwa ji, Jhansi, Department of Horticultural Sciences, Institute of Agricultural Sciences, Bundelkhand University Jhansi (Uttar Pradesh) during
Rabi season of 2020-2021.
The research material comprised of nine treatments along with three replications in Randomized Block Design with planting distance (30 x 30) cm. The data on 80% emergence of plant (7.687 days), stem girth/diamter of plant was maximum (2.18 cm), number of leaves per plant at harvest was maximum (11.3), maximum leaf area at harvest (2.107 cm2), maximum leaf area index (2.107 cm2). The data on 80% emergence of spike at harvest was maximum (82.36), maximum number of floret per spike at harvest (15.803). The data at harvest on length of rachis was found maximum (46.770 cm), at harvest equitorial diameter (3.490 cm), polar Length of individual corm per plant of gladiolus (6.237). The number of corm per plant of gladiolus (6.23), maximum corm yield ((19.710 t/ha), Yield of cormel (16.710 t/ha), All the parameters were significantly influenced by different doses with T5 (BA) 100ppm + (GA3) 100ppm) and T8 (BA) 150ppm+ (GA3) 150ppm in comparison to the control plot T0. Thus it can be assumed that application of growth regulators such as Gibberellic acid (GA3) and Benzyl adenine (BA) should not be overlooked in flower crops under Bundelkhand region. Further researches are required to determine other plant growth regulators which are inevitable in quality improvement of flowers.
