6-Benzylamino purine outperforms Kinetin and Thidiazuron in ameliorating flower longevity in Calendula officinalis L. by orchestrating physiological and biochemical responses

Abstract In view of extending the relatively brief postharvest life flowers by a range technologies, present study elucidates implication 6-benzylamino purine (BAP), kinetin (KN) and thidiazuron (TDZ) on performance flower longevity isolated Calendula officinalis. BAP KN belong to adenine group cytokinins while as TDZ is diphenyl urea compound having cytokinin like activity. The harvested were supplemented with BAP, at various concentrations viz., 25, 50, 75 100 µM one day before anthesis (cup shaped) stage. control was designated distinct set held in distilled water (DW). Our findings revealed substantial enhancement application growth regulators compared control. Vase solutions containing 50 (individually) most effective improving cut flowers. Improvement primarily associated high membrane stability index (MSI), upregulated activities antioxidant enzymes catalase (CAT), superoxide dismutase (SOD) ascorbate peroxidase (APX), besides an attenuated lipoxygenase (LOX) activity petals. As control, treated exhibited higher values soluble proteins, total phenols sugars, lower α-amino acid content petal tissues. However, outplayed officinalis maintaining physiological biochemical
