Comments:
Methods for determination of chlorophyll and carotenoid content (ß-carotene equivalents) adapted from: Knee, M. 1972: Anthocyanin, carotenoid, and chlorophyll changes in the peel of Cox’s Orange Pippin apples during ripening on and off the tree. Journal of Experimental Botany 23: 184-196.
