Seasonal Variation of Chlorophyll in Western Wheatgrass and Blue Grama

Abstract

Chlorophyll concentrations in western wheatgrass and blue grama were evaluated during the period June 29 through October 29, 1965, at the Archer Substation, Cheyenne, Wyoming. Chlorophyll a was more abundant than chlorophyll b in both the western wheatgrass and blue grama during the study period. Concentrations of chlorophyll a and b in the western wheatgrass was greater than in the blue grama. Chlorophyll a and b and total chlorophyll decreased with maturity of the plants.
