| Research Abstract |
Day length longer than 16 hours increased the number of short internodes on the lower part of the main stem and the angle of lateral branches to the main stem, although they affected little on the leaf size of the main stem. A low temperature of20C.-20C. increased the size of the leaves on the main stem and the angle of lateral branches to the main stem as compared with a higher temperature of 25C.-25C., although it decreased the number of short internodes on the lower part of the main stem. We found that the Kiku-type plant shape is allowed to express in the regions where long day length and low temperature are piled up in the growing season.
