文摘
- •
Salvinia minima has high capacity to take up lead.
- •
At the tested concentration lead reduced S. minima photosynthesis.
- •
The lead-induced reduced photosynthesis was mainly associated to root membrane damage.
- •
The reduced photosynthesis was also associated to lead-induced stomatal closure.
