The effects of 24-epibrassinolide corm priming and foliar spray on morphological, biochemical, and postharvest traits of sword lily

The effects of 24-epibrassinolide corm priming and foliar spray on morphological, biochemical,... Gladiolus, or sword lily, is one of the most important cut flowers worldwide. Enhancement of its traits is of paramount importance to the flower industry. The application of 24-epibrassinolide (EBR) by corm priming and plant foliar spray to improve morphological, biochemical and postharvest characteristics of Gladiolus grandiflorus cv. Oscar were investigated. Concentrations of 0.5, 1, and 2 µM EBR as well as distillated water as a control were used for both corm priming and foliar spray treatments. Results showed that the highest levels of corm sprouting and flower spike emergence were obtained at 1 µM EBR. Floret numbers, flower spike fresh and dry weight, and vase life showed the highest values at 1 µM EBR combined treatments. The combination of corm priming at 2 µM and foliar spay at 1 µM EBR, showed the highest effect on malondialdehyde reduction. The highest activities of antioxidant enzymes such as catalase, peroxidase, and superoxide dismutase were obtained in combination of 1 µM EBR corm priming and 1 µM EBR foliar spray. EBR treatments prolonged vase life from 8 to 14 days and significantly improved gladiolus morphological and biochemical traits. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Horticulture, Environment, and Biotechnology Springer Journals

Abstract

Gladiolus, or sword lily, is one of the most important cut flowers worldwide. Enhancement of its traits is of paramount importance to the flower industry. The application of 24-epibrassinolide (EBR) by corm priming and plant foliar spray to improve morphological, biochemical and postharvest characteristics of Gladiolus grandiflorus cv. Oscar were investigated. Concentrations of 0.5, 1, and 2 µM EBR as well as distillated water as a control were used for both corm priming and foliar spray treatments. Results showed that the highest levels of corm sprouting and flower spike emergence were obtained at 1 µM EBR. Floret numbers, flower spike fresh and dry weight, and vase life showed the highest values at 1 µM EBR combined treatments. The combination of corm priming at 2 µM and foliar spay at 1 µM EBR, showed the highest effect on malondialdehyde reduction. The highest activities of antioxidant enzymes such as catalase, peroxidase, and superoxide dismutase were obtained in combination of 1 µM EBR corm priming and 1 µM EBR foliar spray. EBR treatments prolonged vase life from 8 to 14 days and significantly improved gladiolus morphological and biochemical traits.
