White young shoots from albino tea cultivars have high level
of amino acids and are rare and valuable materials for
processing green tea. The effects of temperature on leaf
colour, accumulation of chlorophylls and leaf
ultrastructures of an albino tea cultivar ‘Xiaxueya’ were
investigated. The study showed that the shoot albino
phenomenon of ‘Xiaoxueya’ was controlled by temperature. The
development of chloroplast from etioplast and the
accumulation of chlorophylls a and b were blocked and albino
shoots were observed at 15˚C. However, the albino phenomenon
was reversed when the plant was grown at 20˚C or above. The
authors recommended that the albino tea cultivars should be
grown at high altitude or high latitude areas so as to
prolong the production season of albino tea shoots.
