| 内容記述 | A community containing both normal and variegated Japanese butterbur (Petasites japonicus) was found in a field at the Fukuoka University of Education campus in April 2012. Variegated Japanese butterbur leaves contained fewer chloroplasts, chlorophyll, and starch grains in green sectors, and lacked chloroplasts, chlorophyll, and starch grains in chlorotic (white) sectors, compared to those of normal Japanese butterbur. To investigate the effect of environmental factors on variegated Japanese butterbur leaves, both normal and variegated Japanese butterbur were irradiated with low (0.35 W m-2) and high (1.67 W m-2) levels of ultraviolet-B (UV-B). Our results indicate the following order of sensitivity to UV-B irradiation: white sectors in variegated Japanese butterbur leaves are the most sensitive to both low- and high-level UV-B irradiation, green sectors in variegated Japanese butterbur leaves are second, and green leaves of normal Japanese butterbur are third. Therefore, there is a positive correlation between tolerance to UV-B irradiation and content of chloroplasts, chlorophyll, and starch grains in Japanese butterbur leaves. Because starch grains are effective UV-B reflectors whereas chlorophylls are not efficient UV-B absorbers, starch might contribute primarily to UV-B tolerance. Solar UV-B irradiation might be one of the causes of scorching observed in white sectors of variegated Japanese butterbur leaves in the field. | |||||
