ANALYSIS OF CHEMICAL INTERVENTIONS FOR ENHANCING VASE LIFE IN AFRICAN AND FRENCH MARIGOLDS

Abstract

The vase life of cut flowers is a crucial factor in the floriculture industry, influencing marketability, consumer preference, and economic returns. African marigold (Tagetes erecta L.) and French marigold (Tagetes patula L.) are widely used for ornamental and religious purposes; however, their postharvest longevity is limited due to rapid senescence, vascular blockage, ethylene sensitivity, and microbial contamination. This review comprehensively analyses the role of various chemical treatments, their mechanisms of action, and their comparative effectiveness in extending vase life. Additionally, recent advancements, limitations, and future research prospects are discussed, with an emphasis on sustainable and eco-friendly approaches. This study investigates the efficacy of eco-friendly and chemical-based treatments in extending the vase life of Tagetes erecta (African marigold) and Tagetes patula (French marigold). The research evaluates the effectiveness of various natural preservatives (such as plant extracts, essential oils, and organic acids) and synthetic chemicals (such as silver nitrate, sodium hypochlorite, and citric acid) in maintaining postharvest freshness.
