As sessile organisms, plants are subject to numerous environmental insults. Of these, salinity is one of the most widespread and important in terms of limiting plant distribution and productivity. Molecular studies have established that plants challenged by high salinity respond by increasing expression of specific genes. A functional role for the products of such genes in stress tolerance has not been established, however, and little is known about the biochemical mechanisms that allow plants to tolerate osmotic stress.

CoordenaÃÃo de AperfeÃoamento de Pessoal de NÃvel Superior<br>A interpretaÃÃo de dados do sensoriamento remoto fundamenta-se, basicamente, na anÃlise do comportamento da reflectÃncia espectral dos materiais no intervalo de comprimento de onda do visÃvel ao infravermelho de ondas curtas (400 a 2500 nm). Para isso, pode-se usar a espectrorradiometria de reflectÃncia, que à uma tÃcnica capaz de medir, em diferentes comprimentos de ondas, a energia eletromagnÃtica refletida da superfÃcie dos materiais e representÃ-la na forma de um grÃfico denominado curva de reflectÃncia espectral. O poder analÃt

Annotation:
Deux exemples de mise en valeur de sols sales en milieu semi-aride tunisien sont analyses. Situes dans la partie littorale de la basse vallee de la mejerda, ils constituent deux modeles de recuperation de sols salins. Il s'agit de la lunette d'el mabtouha et du perimetre de kalaat landelous dont les sols, initialement tres salins et tres sodiques, ont evolue dans des conditions et a des vitesses differentes pour aboutir a des terres cultivables. Dans le premier cas, la recuperation s'est produite sous conditions naturelles, alors que dans le second cas, c'est l'artificialisation du regime hydr
