Effect of Ozone Water on Cut Flower Quality by Solution Culture Dendranthema grandiflorum 'Baegkwang'

摘要

This study was conducted to determine the effect of ozone water treatment on growth and cut flower quality in hydroponics of Dendranthema grandiflorum 'Baegkwang'. In first flowering, 30 min/h ozone water treatment was more effective in length of cutflower and flower diameter than the other treatments. Flowering date was shorted about 4 to 9 days compared to control. In secondary flowering, growth were improved by ozone water treatment. Especially plant height and length of cut flower were high, flower diameter was more improved and days to flowering were shorter by 30 min/h ozone water treatment. Also, photosynthesis and transpiration rates were high, microbial counts were decreased, but yield was increased.
