Webpheophytin. In environments with high chlorophyll b concentrations, we strongly recommend using the Welschmeyer (non-acidification) method. High concentrations of chlorophyll c can result in a slight overestimation of chlorophyll a and an underestimation of pheophytin a sometimes even resulting in negative pheophytin readings. Webfication; that is, the pheophytin absorbs less light per unit weight than its respective chlorophyll. The method proposed is similar to that described by Vernon (1960) and others reviewed by Holden ( 1965), but absorb- ancies are measured at only two wave- lengths, 750 and 665 rnp, before and after
