Dose Effect of Phytosanitary Irradiation on the Postharvest Quality of Cut Flowers

Dose Effect of Phytosanitary Irradiation on the Postharvest Quality of Cut Flowers

Song Kwon et al., J. People Plants Environ.

The present study was conducted to determine the effects of electron beam irradiation on the postharvest quality of cut flowers.

Cut flowers were irradiated with electron beam at 100, 200, 400, 600, 800, 1,000, and 2,000 Gy with a 10 MeV linear electron beam accelerator to evaluate their irradiation tolerance.

Postharvest quality was determined by monitoring fresh weight loss, flower longevity, flower diameter, flowering rate, visual quality of flowers and leaves, and chlorophyll content.

Cut flowers showed a radiation-induced damage with increasing the irradiation dose.

Flower longevity and fresh weight of cut flowers decreased when the irradiation dose was increased.

Flower bud opening was also inhibited in a dose-dependent manner.

The effective irradiation doses for 10% reduction of postharvest quality (ED10) values were 144.4, 451.6, and 841.2 Gy in the ‘Medusa’ lily, ‘Montezuma’ carnation, and ‘Rosina White’ eustoma, respectively.

Although tolerance of cut flowers to electron beam irradiation vary according to species, cultivars, or maturity stage conditions, it is conceivable that ‘Montezuma’ carnation and ‘Rosina White’ eustoma could be tolerated and maintained overall postharvest quality up to 400 Gy, the generic irradiation dose approved by the Animal and Plant Health Inspection Service (APHIS) and the International Plant Protection Convention (IPPC) for postharvest phytosanitary treatments.
