Abstract
Mokara orchid inflorescences are one of the most important orchid hybrids for cut flower exports. The objective of this research was to study the physiological changes of Mokara inflorescences during storage. Inflorescences of Mokara Panee, Mokara Red, Mokara Nora 'Yellow', Mokara Chark Kuan 'Pink' and Mokara Nora 'Pink' were harvested from an orchid nursery at a commercial maturity stage and were transported to the laboratory. The stem ends were re-cut to ensure a uniform size before placing in distilled water at 25ฐC. Ethylene production, respiration rate, fresh weight, water uptake and bud opening were measured daily and vase life was noted at 50% of floret senescence. Mokara Nora Pink had the lowest thylene production, Mokara Panee had the highest respiration and bud opening, while Mokara Red had the highest fresh weight and water uptake. The display life of Mokara Panee, Mokara Red, Mokara Nora 'Yellow', Mokara Chark Kuan 'Pink' and Mokara Nora 'Pink' was 13, 11.6, 12.4, 12.4 and 12.7 days, respectively. These results indicate that the vase life and physiological changes of cut Mokara inflorescences depend on the cultivar.
