Abstract
Gladiolus and Amaryllis are prominent flowering plants in Pakistan, grown primarily for their aesthetic appeal. However, due to the lack of proper postharvest management techniques, farmers and traders face significant losses. The study examined the influence of 2.5 & 5% of foliar application of ginger and citrus extracts on vase life and postharvest performance of Gladiolus and Amaryllis flowers. Different concentrations of the extracts were applied, and the effects on vase life, water uptake, floral head diameter and protein content etc., were measured. GE 5% (50ml/L) was found to increase the performance of cut flowers, which further increased the longevity of all Gladiolus and Amaryllis cultivars tested up to eight days and the longest vase life by 20.98 and 17.97 days, respectively. The maximum change in fresh weight (91.7 g), the increase in water uptake (27.33 and 25.97ml), flower head diameter (124.27 and 136.32 mm), dry weight of petal (1.13 and 1.29 g), total soluble solids (5.88 & 6.97 °Bx), highest protein content (66.33 and 65.02 mg g−1). The activities of total phenolic compound (TPC) 2.39 and 2.52 mg 100g-1), superoxide dismutase (SOD) (3.54 and 3.38 U g−1), catalase (CAT) (2.18 and 2.03 μ mol H2O2), and peroxidase (POD) (1.71 and 1.67 μ mol H2O2), also showed an increase. These results suggest that the use of 5%, ginger extract can significantly improve the postharvest management of gladiolus and amaryllis in Pakistan, providing growers and retailers with a viable solution to their current challenges
