The study aimed to investigate the "Germicidal Interventions to Prolong Vase Life and Quality of White Friendship Gladiolus Cultivar". The research was conducted in the experimental laboratory of the Department of Horticulture, Faculty of Agriculture, Annamalai University, Annamalai Nagar, during 2020-2021. The experiment employed a completely randomized design with nine treatments, each replicated thrice. The treatments included four preservative chemicals: Sodium dichloroisocyanurate dihydrate at 0.6 and 0.8 mg/l; 8-Hydroxy Quinoline Sulphate at 150 and 300 ppm; 8-Hydroxy Quinoline at 150 and 250 ppm; and silver nitrate at 50 and 100 ppm. All treatments contained 4% sucrose, along with a control group (distilled water). The results revealed that treatment T₆ (8-HQS at 300 ppm + 4% sucrose) exhibited the maximum water uptake (61.67 g/s), water balance (6.95 g/s), fresh weight change (149.33%), and vase life (11.19 days) compared to the control. Additionally, T₆ showed the least optical density of the vase solution (0.0207). Therefore, the findings lead to the conclusion that employing a vase solution formulated with 8-HQS at 300 ppm and 4% sucrose proved to be the most effective in extending the vase life and maintaining the quality of gladiolus spikes cv. White Friendship.
