초록

This study examined the capacity of tea plants to absorb vanadium with the purpose of developing a special tea with added functional components. Chelated vanadium was supplied to 'Ryohu' or 'Yabukita' tea plants using afertigation system or foliar spray at different concentrations in different tea seasons. Tea leaves treated by fertigation above 6.0 ppm showed a higher vanadium content than the control, and the fertigation supply at the early stages of one leaf perbud increased the vanadium content of the tea leaves compared tofertigation at the later stages of three leaves perbud.
Potted plants showed a higher absorption rate than the plants growing in anopen field. Sprayingonce 15 days before harvesting had a dilution effect as the plants grew and increasing thespray timesto up to three times had atendency to increase the vanadium content in tea leaves, which was in accord with the different tea seasons. The vanadium contents were not the same in the tea leaves at different positions harvested after being treated with chelated vanadium, and the old leaves located at the lower part of the shoots had a higher content, which might be caused by dilution as the shoots grow.
