• 1. The author investigated the refractivity of the press juice of tea leaf at different leaf positions, developing stages, and plucking seasons, using an Abbe's refractometer.<BR>2. The water of the tea shoot tissue was contained with decreasing order in the stem, the upper leaf and the lower leaf.<BR>3. The refractivity of the press juice of the lower leaf was higher than that of the upper one, and that of the stem was the lowest. But in the case of the tissue powder infusion, the order of the upper and lower leaves was reverse.
