Variation of Mineral Contents at Different Leaf Positions on the Stem of Tea Plant

In the first and third plucking seasons, the mineral contents (silicon, phosphorus, potassium calcium, magnesium, iron, manganese and sulphur) in leaves at different positions on the stem of tea plant were determined.It was observed that in the leaves of upper position contained more phosphorus, potassium and magnesium but less silicon, calcium iron and manganese and in those of lower position, the opposite relation existed. Sulphur contents of the leaves did not varied at any position.This tendency was almost same in both plucking seasons.
