The authors applyed the method of Stuart DUNN using the adsorption of dye on the test of variental difference of cold resistance of tea plant. The results were summarized as follows. 1. Adsorption of dye of malachite-green was greater corresponding nith the degree of cold resistance of variety, these facts that the older plants withsood cold better than the younger ones, that leaves were injured by cold more than branches and that the cold resistance was increasing up to the coldest season, all agreed well with the chages in the degree of dye adsorption. 2. This test by different dyes varied in their adsorptive action, i.e. basic dyes were adsorped well by stronger varieties and acidic dyes mere diametrically apposed. Malachite-green and easin were suitable dyes for this test. 3. In general, the test in dried tissues agreed with the results in fresh tissues on the relation between adsorption and cold resistance, but fresh leaves from older plants were the best samples for this test.
