Lipids were extracted from fresh, field-grown coastal bermudagrass (Cynodon dactylon (L.) Pers.) and the fatty acids determined by gas chromatograpby. Total fatty acid levels (dry weight basis) increased during the day and reached a single maximum at sunset in 2-week-old grass; whereas, in older grass, tbe fluctuations in fatty acid levels sbowed two maxima. Tbe first maximum occurred 4 b after sunrise and the second maximum occurred at sunset. Total fatty acid levels, based on dry weight, decreased during the first 6 weeks of growth and changed very little after an additional 4 weeks' growth in bermudagrass leaf blades. Chlorophyll levels (dry weight basis) continuously decreased during the entire growth period (10 weeks). Chlorophyll alb ratios increased at sunset in 2-and 6-week-old grass, but this ratio did not change during the day in subsequent growth stages. The results of these experiments show that stages of maturity affected fatty acid fluctuations during the day as well as total fatty acid and chlorophyll levels in Coastal bermudagrass leaf blades. Cblorophyll ajb ratios varied independently of fatty acid levels.

“…Chlorophyll a was considered the precursor of chlorophyll b, based on early pulse-labeling experiments. By incubating homogenates of soybean leaves with 14C-Iabeled chlorophyll a, researchers obtained significant yields of 14C-labeled chlorophyll b (Ellsworth et at., 1970). The accepted view favored a sequential scheme of chlorophyll a, assuming as precursor a special pool of more labile young chlorophyll a (Shlyk, 1971).…”
