Variation in Petal and Leaf Wax Deposition Affects Cuticular Transpiration in Cut Lily Flowers.

ABSTRACT: The vase life of cut flowers is largely affected by post-harvest water loss. Cuticular wax is the primary barrier to uncontrolled water loss for aerial plant organs. Studies on leaf cuticular transpiration have been widely conducted; however, little is known about cuticular transpiration in flowers. Here, the cuticular transpiration rate and wax composition of three lily cultivars were determined. The minimum water conductance of tepal cuticles was higher at the green bud than open flower stage. Lily cuticular transpiration exhibited cultivar- and organ-specific differences, where transpiration from the tepals was higher than leaves and was higher in the 'Huang Tianba' than 'Tiber' cultivar. The overall wax coverage of the tepals was higher compared to that of the leaves. Very-long-chain a
