This investigation was conducted under a naturally ventilated polyhouse, in the Department of Horticulture, SHUATS, Prayagraj, Uttar Pradesh. In December 2020 with records taken from the month of February to month of March 2021. There were nine treatments comprising two growth regulators Gibberellic acid (GA3) (at 200, 250, 300, and 350 ppm), and Naphthalic Acetic Acid (NAA) (at 50,100,150, and 200 ppm) along with control. The whole experiment was laid out as a Randomized Block Design (RBD) with three replications. The results revealed that among the Lilium cv. LITOUWEN, the foliar application of 250 ppm GA3 significantly increased the number of leaves per plant (66) with enhanced days to bud initiation (25.7 days). The number of bud per plant was 2.8 and stem length was 43.4cm respectively., GA3 at a concentration of 350 ppm enhanced vase life (7.9 days). and NAA at a concentration of 100 ppm enhanced the number of bulblets (3.3).

“…Plants sprayed with gibberellic acid at 100 ppm (T3) showed maximum flowering period (128.2 days) and in situ flower longevity at 30 DAS (3.87 days), 60 DAS (4.07 days) and 90 DAS (4.10 days) in pooled analysis. Gibberellic acid has been known to extend flowering period as well as flower longevity and shelf life with it's hydrolyzing effect on amylase enzyme that converts starch reserves to reducing sugar as reported earlier in chrysanthemum (Singh et al, 2018) [18] .…”

Investigation was done to study the effect of foliar spray of plant growth regulators on growth and flowering of potted hibiscus plants grown in pot during 2017-18 and 2018-19. Application of gibberellic acid, benzyl adenine and salicylic acid at different concentrations found significant in influencing the vegetative growth, flowering parameters and plant pigments of Hibiscus rosa-sinensis plants during both the years as compared to untreated plants (control). Plants sprayed with 100 ppm gibberellic acid resulted in to maximum plant height (24.90, 26.77 and 28.93 cm), plant spread and leaf area (15.55, 16.17 and 16.48 cm 2 ) respectively at 30, 60 and 90 days after spraying (DAS). While, maximum number of branches (4.63, 5.45 and 6.02) and leaves (26.57, 31.33 and 35.65) was recorded in plants sprayed with 50 ppm gibberellic acid, respectively at 30, 60 and 90 days after spraying (DAS). Maximum number of flowers per plant, flowers per branch, flower diameter, flowering period and in situ flower longevity was observed in hibiscus plants sprayed with 100 ppm gibberellic acid. The plants receiving the same treatments also increased chlorophyll content in leaves (19.50, 20.37 and 20.85 mg/g) and anthocynin in flower (17.03, 18.65 and 20.20 mg/g), respectively at 30, 60 and 90 days after spraying (DAS).

“…Plants treated with double spray at GA 3 100 mg L −1 produced an increase of 69.9, 33.0, 17.1, and 40.0% in number of leaves, number of shoots, shoot diameter and shoot length as compared to control ( Table 1 ). The study of [ 36 , 37 ] also recorded an increase in the number of shoots and shoot length with GA 3 at 100 mg L −1 in hortensia ( Hydrangea ) and chrysanthemum ( D. grandiflora ). Likewise, findings were reported by Ref.…”
