Table 2 Decay components for the single and two-component models for disks in air. Treatments with no data for alpha symbol and k1 indicate that a single exponential model was used and the results for these are listed under k2. Decay parameters were calculated for a 13-month period. Species: A. germinans (Ag), L. racemosa (Lr) and R. mangle (Rm)
