Abstract

Lily (Lilium spp.) is widely appreciated for its beauty and color diversity, making it an important cut flower. However, its postharvest quality is limited, requiring specific treatments that need to be investigated, such as the combined application of sucrose and 6-benzylaminopurine (BAP). In this study, our aim was to explore the efficacy of pulsing solutions containing various concentrations of BAP combined with sucrose in preserving the post-harvest quality of ‘Nova Scotia’ lilies. The experimental design employed was a completely randomized factorial scheme, with five treatments (25 mg L-¹ BAP + 100 g L^-1 sucrose; 50 mg L^-1 BAP + 100 g L^-1 sucrose; 75 mg L^-1 BAP + 100 g L^-1 sucrose, Chrysal® commercial formula, and control with deionized water) and four evaluation dates. Alongside visual assessments, including tepal and leaf coloration, we quantified total carbohydrate content, fresh mass variation, solution uptake, and floral longevity. Our findings underscore the significant role of BAP and sucrose application in maintaining the post- harvest quality of ‘Nova Scotia’ lily flowers. Notably, even at lower concentrations, these substances have demonstrated a considerable enhancement in fresh mass and prolonged flower longevity.
