Notes:
Seasonal changes in adenylate levels and adenylate energy charge (AEC) of four perennial marsh plant species growing in their natural environment were monitored. Leaf tissue was collected bimonthly from Spartina patens (Aiton) Muhl., S. cynosuroides (L.) Roth., S. alterniflora Loisel. and Distichlis spicata (L.) Greene using a method designed for field sampling of adenine nucleotides. The AEC of all four plant species exhibited a strong seasonal variability. Comparison with above-ground biomass (g m−2) demonstrated a close relationship between AEC and growth. The AEC ratios peaked in early spring or summer (0.78-0.85) and then declined in late summer and early fall. The ATP/ADP and ATP/AMP ratios also fluctuated seasonally and in a pattern similar to that of the AEC.
