Abstract:
An experiment was conducted to determine the effect of bending and plant growth regulator on cut flower yield and quality of rose cv. Top Secret under protected conditions. From the output of the study, a significant effect of bending at shoot junction (B₁) was found with respect to maximum flower bud diameter (1.84 cm), maximum flower head diameter (7.57 cm), maximum stalk length (46.06 cm), highest stalk diameter (4.93 mm), maximum number of cut flower per plant (1.98) and per 1000 sq.m. (13856.31), maximum fresh weight of flower (13.80 g), highest in-situ longevity of flower (15.12) and maximum vase life of flower (10.43). The result of plant growth regulator was also observed significant and maximum flower head diameter (7.18 cm), the maximum number of cut flowers per plant (1.98) and per 1000 sq.m. (13830.07), highest fresh weight (13.68 g), highest dry weight (3.00 g), maximum in-situ longevity of flower (15.65) and maximum vase life of flower (10.31) were noted in the treatment of 200 ppm benzyl adenine (G₂). Among the interactions, bending at shoot junction with 200 ppm benzyl adenine (B₁G₂) significantly recorded maximum flower head diameter (8.65 cm), maximum in-situ longevity of flower (18.33) and maximum vase life of flower (12.00).
