Effect of Pre and Postharvest Factors on Vase life of Gladiolus or Effect of Different Floral Preservatives on Vase Life of Gladiolus

Abstract

Gladiolus is a popular ornamental and cut flower grown globally. However, the vase life of gladiolus flowers is relatively short due to physiological factors such as water stress, carbohydrate depletion, microbial activity, and ethylene exposure. This review discusses various preharvest and postharvest factors that influence the vase life of gladiolus flowers. Genetic factors, environmental conditions like temperature and humidity, and biotic stresses can impact vase life during the preharvest stage. Postharvest factors such as ethylene production, carbon dioxide levels, and pest/disease issues also play a crucial role. The use of chemical preservatives like sucrose, salicylic acid, and growth regulators like gibberellic acid have been found effective in extending the vase life and maintaining the quality of cut gladiolus flowers. Integrated management of these factors can help improve the postharvest longevity and marketability of gladiolus as a cut flower.
