Para a epiderme adaxial e abaxial, índice estomático e razão PP/LF não houve diferenças significativas em nenhuma situação estudada. Para o parênquima. O índice de vulnerabilidade de Carlquist (IVC = diâmetro dos elementos Entretanto, o índice estomático aumentou 36% em todos os tratamentos contendo. El índice estomático es mayor en la cara abaxial. La lámina foliar posee ambas epidermis glabras y uniestratificadas. Inmediatamente por debajo de esta.

Anatomical and physiological mechanisms of water hyacinth plants to Arsenic contamination tolerance.

Anatomical and physiological mechanisms of water hyacinth plants to Arsenic contamination tolerance

I ; Castro, E. II ; Oliveira, C. III ; Pires, M. IV ; Pasqual, M.

This work aimed to evaluate the anatomical and physiological characteristics of Eichhornia crassipes in response to arsenic stress. The anatomical characteristics observed on the leaves of the inidce under higher arsenic levels showed an increase in stomatal density, stomatal index and spongy parenchyma thickness.

Root anatomy showed no toxic evidences at any arsenic level; changes in the xylem and phloem characteristics were exhibited by the roots in the arsenic treatments, but no damage was caused to its structure and function. Thus, stress caused by arsenic intoxication at the levels tested, is not evident on E. Eichhornia crassipesecological anatomy, antioxidant system, photosynthesis.
