Pickings were made on April 27, 1948, and January 1, April 7, and May 10, 1949, for the various treatments. 

F3 H activity from the microsomal fraction of cell cultures of C. sinensis (L.) Osbeck cv. Hamlin (Hamlin) has been biochemically characterized and verified to be a cytochrome P450 [113]. The enzyme was shown to use naringenin, dihy-drokaempferol, and kaempferol, but not apigenin as substrates. E3 H activity was also demonstrated from young leaves of Hamlin orange as well as from the flavedo of Hamlin orange, Marsh grapefruit, and Lisbon lemon fruits [113]. The fact...
