Evaluating the effectiveness of innovative preservation solutions for cut flower gladiolus (Gladiolus grandiflora L.)

Abstract

The present experiment was carried out to evaluate the “Evaluating the Effectiveness of Innovative Preservation Solutions for cut flower Gladiolus (Gladiolus grandiflora L.)’’ was conducted during the Rabi season of 2024-25. The experiment involved laboratory studies. The experiment was conducted at the floriculture and landscaping laboratory under Pt. Kishori Lal Shukla College of Horticulture, and Research Station, Rajnandgaon (C.G.). Mahatma Gandhi University of Horticulture & Forestry, Durg (C.G.). A complete random design was used for statistically analysed of data, which consisted of 10 treatments and replicated thrice. The Red majesty flower variety was used in this experiment. The treatments comprised Citric Acid, Ampicillin capsule, Rifampin capsule, tamarind juice, coconut juice, lime juice along with a distilled water control. Solutions were prepared by dissolving the required amount of preservation solution in 1 L of distilled water. The treatment 9 (Rifampin capsule 300 mg + coconut juice 30 ml + tamarind juice 30 ml + lime juice 30 ml/L) recorded the lowest Physiological Weight Loss (11.7%), and Maximum Diameter of Floret (9.3cm), and maximum Floret opening (97.8%), and longest vase life (8.5 days), and The greatest water loss (34.0%) occurred in Treatment T5 (Ampicillin capsule 250 mg + coconut juice 30 ml + tamarind juice 30 ml + lime juice 30 ml/L). In contrast, the untreated control (T₀) consistently recorded inferior values across all traits. The study concludes that treatment 9 (Rifampin capsule 300 mg + coconut juice 30 ml + tamarind juice 30 ml + lime juice 30 ml/L is the most effective treatment for prolonging of vase life of gladiolus.
