(1) For the purpose of injection of zinc sulphate solution, a tube (connected with the bottle containing 1.4 M zinc sulphate solution), was inserted into a previously bored hole in the southern side of the trunk, and then this solution was very slowly injected into the tree.(2) The procedure with which to determine the quantity of Zn in Akamatsu needles was, generally, based upon WAIKLEY'S method.(3) Before the injection, a certain quantity of Zn (16〜21 p. p. m.) in dry matter (needles) was measured.(4) After 9 days of injection, Zn in needles increased more in quantity in the upper part of the trunk from injection hole than in the lower, and more in the southern side of the trunk (at this side the injection was carried out) than inthe northern side.
