Some histochemical observations were made on anther tissues of rice plants treated under artificial low temperature conditions (9-10'C for 24 hours or 17'C for 5 days) in the summers of 1956 and '57, the res;ults of which are reported here. Three improved paddy varieties, viz., Fujisaka No. 5, Towada and Norin No. 16, were used, the first two being known to be cold resistant and the last one susceptible. 1. The histochemical deviation from the normal process occur especially pronouncedly in the three tissues, viz., transitory, pollen, epidermis and parenchyma. 2. During the period from the stage just before the PMC divisian to that of the extine formation, transitory tissue in the affected anther always shows remarkable increase in the content of reducing substances and decrease in that of polysaccharides. 3. In affected tapetum increased peroxidase activity and the content of reducing substances are bbserved during the period from the first to second contracting stage of pollen.
