Abstract

|
Golden-Bells, which show distyly, are cultivated broadly in Korea. We found some differences in flower and flowering between short-styled and long-styled flowers. Flower diameter, petal width and length of short-styled flower were greater than long-styled flower. Flower color of short-styled flower was yellower than long-styled flower. The measurement of chromaticity showed that darker color of short-styled flower was not due to b-value (yellow direction) but due to a-value (red direction). Petal carotenoid contents of short-styled flower was higher than long-styled flower. The flowering of short-styled flower was earlier than long-styled flower. Total blooming period of long-styled flower was longer by 2 days than short-styled flower, so the long-styled flower appeared to bloom for longer period than short-styled flower.
