Germination, growth and photosynthesis of soybean
seedlings were all inhibited by exposure to Cd or FLT
individually or in combination, and there were significant
interactions between both toxicants. Exposure to Cd and
FLT simultaneously had greater effect on germination,
growth and photosynthesis of soybean seedlings. Simultaneous
exposure to Cd and FLT resulted in antagonism
relative to effects on germination at a concentration of
(1 mg FLT/L), whereas the interaction was synergistic
when concentrations of FLT and Cd were higher. The
type of interactive effect between 5 or 10 mg Cd/L and
1 or 5 mg FLT/L on shoot growth and photosynthesis of
soybean seedlings was mainly antagonism, whereas for
root growth, the antagonism and synergism were both
observed.
