Seed Vigor
Initial seed vigor as measured by the AA test ranged from 83
to 97% (Fig. 1G). In CS, vigor values of the fungicide plus
insecticide-treated seeds and the untreated seeds were ≥80%
after 4 mo of storage and did not differ significantly between
seed treatments (Fig. 1H). Similarly, the AA percentage for
fungicide-treated seeds stored in the WS was significantly
higher (79%) than that of fungicide plus insecticide-treated
seed (71%) and untreated seed (70%) (Fig. 1H). At 4 mo,
seed vigor was similar (≤60%) for all seed treatments and
seed lots stored in the WH and significantly lower than seed
lots stored in the CS (82%) and the WS (73%).
After 8 mo of storage in CS, the seed vigor values of
fungicide-treated seeds were higher (84%) compared to the
vigor values of the same treatment at 4 mo (79%). The fungicide-
(84%) and fungicide plus insecticide-treated seeds
(87%) had higher seed vigor than untreated seeds (68%) after
8 mo in CS (Fig. 1I). Seed vigor of seed lots in WS declined
