Studies on the properties and structure of polyphenoloxidase during apple ripening

, : Studies on the properties and structure of polyphenoloxidase during apple ripening. Immunitet i Pokoi Rastenii: 229-235

The polyphenoloxidase activity of the fruit chloroplasts of 2 apple cvs changed during fruit growth and ripening. The polyphenoloxidase in the chloroplasts of green fruits consisted of one high-molecular weight component. As the fruit grew and ripened enzyme components with lower molecular weight appeared.
