Respiration in Corn With Special Reference to Catalase

The Inter-Relations of Catalase, Respiration, After-Ripening, and Germination in Some Dormant Seeds of the Polygonaceae

“…Appleman (I9I8), Crocker and Harrington (I9I8), Davis (1930), and others have satisfactorily shown that catalase is directly correlated with respiration in a great many cases. Rhine (1924) and Lantz (1927) found that catalase activity and respiration do not always follow the same curve. Catalase has been shown by Davis (1925), Neller (1931), and Nemec and Duchon (1921, 1922 to be a definite indicator of viability, and Flemion (I93I) and Pope (1932) have shown that it is directly related to growth.…”

Effects of Environmental Factors on Oxidizing Enzymes of Rose Mallow Seeds

“…Catalase activity in germinating seeds decreases when the food supply is exhausted according to the findings of LANTZ (17) and DELEANO (7). This is shown to be the case in the Hibiscus seeds.…”

“…Bark of the roots had a higher activity than did bark from the trunk and the bud tissues were the most active of any on the tree. Strains of corn high in oil content displayed the greatest catalase activity, and the high protein strains ranked second when compared with low fat and low protein strains, according to LANTZ (17). BILETZKY (4) contends that more attention should be given to the factors concerned in the production of the plant and their relation to the catalase content.…”
