Abstract

Climate change is predicted to have a strong impact on future horticultural production, thus requiring crop adaptation to new environmental conditions.
In this study, we investigated the effects of low sunlight and high temperature on the quality of cut flowers of ‘Cherry Tessino’ spray carnation grown in planters during summer in a cold region of Hokkaido, Japan.
When carnations were grown under normal conditions, flower buds began to form on lateral branches 9 weeks after pinching, and the rate of flower bud differentiation exceeded 50% after 10 weeks.
All examined lateral branches elongated after flower bud differentiation.
We next evaluated the impact of low sunlight (75% shading for 3 weeks) during different growth periods and found that low sunlight immediately before flower bud differentiation reduced the number of flower buds.
In a third experiment, we investigated the effects of low sunlight, high temperature, and their combination on flower bud differentiation.
For the high-temperature treatment, plants were exposed to 35°C during the day and 30°C at night for 1 week in a phytotron.
Low sunlight and high temperature strongly suppressed lateral branch elongation.
Calyx splitting due to partial petalization occurred frequently in cut flowers subjected to high-temperature conditions.
In future studies, we plan to evaluate the effects of high temperature on different carnation cultivars.
