ASPECTOS CITOMORFOLÓGICOS DO ESTRESSE SALINO EM PLÂNTULAS DE ARROZ (ORYZA SATIVA L.)

The goal of this work was to perform a cytomorphologic study of rice plants upon salt stress (170 mM NaCl). The effects of salinity on cell structures were analyzed by optical and electron transmission microscopy. An early differentiation process could be observed in stressed plants, however the mos...

Sumario:The goal of this work was to perform a cytomorphologic study of rice plants upon salt stress (170 mM NaCl). The effects of salinity on cell structures were analyzed by optical and electron transmission microscopy. An early differentiation process could be observed in stressed plants, however the most striking deleterious effect was found in the thylacoid membranes of chloroplasts. These results indicate a correlation between the previously described accumulation of sodium and the cytomorphological changes in chloroplasts of mature tissues of rice plants.
