| Abstract;Ultraviolet (UV) radiation induced the production of the phyioalexin, scoparone (6,7-dimethoxycoumarin), in the flavedo of various kinds of citrus fruits. We measured the changes in scoparone concentration after UV radiation in citrus leaves and fruits harvested in August and December. The changes in scoparone concentration were lower in young leaves (August) than in mature ones (December). Young leaves of all cultivars harvested in August, except for those of 'Eureka' lemon, produced less than 100ug g'-1'FW. The concentration in the fruits was also lower in young than in mature specimens. Changes in the scoparone concentration and the rate of increase varied with cultivars, organs, and the time of harvest. (author abst.) |
