In order to elucidate the physiological mechanism of carotenoid formation in citrus fruit, we determined a - carotene, p - carotene, lycopene, p - cryptoxanthin, zeaxanthin and lutein content in 53 varieties that belong to various citrus types using hplc, analyzed the possible connection between color formation and carotenoid accumulation, and studied the effects of light. ga3 and mpta on carotenoid biosynthesis in peel of citrus fruit. the results are summarized below
