Abstract
Effects of air-blowing treatment on the yield, characteristics of leaf stomata, transpiration and vase life of the cut stems were investigated in rose (Rosa 'Asami Red') plant. The yield of cut flowers was increased by air-blowing treatment, especially in winter when humidity in a greenhouse was high. Cut roses obtained from the plants given air-blowing treatment had a reduced stomatal size compared to the control group. The cut roses in the air-blowing treatment group showed a lower transpiration rate after harvest than those in the control group. The air-blowing treatment resulted in delayed bent neck symptom and longer vase life of cut stems. Air-blowing may be considered to enhance CO_2 absorption and transpiration in a greenhouse by thinning leaf boundary layer and bringing functional stomata. It is concluded that air-blowing treatment is an effective method to increase yield and to prolong the vase life of cut roses.
