Résumé
Red kidney beans were grown in nutrient . solutions containing 0$ 2, 3s and ^ bars osmotic pressure (OB) created by the gradual addition of sodium chloride„ Trifoliate leaves initiated after salt addition were reduced in number and area* Photomicrographs of epidermal surfaces demon- 1 strated that the reduction in leaf area was the result of a retardation in cell expansion. Cells per stornate were similar in ratio in salt and control leavesg suggesting no salt induced reduction of cell division* Photomicrographs of leaf cross sections recorded a wide range of thicknesses in control leaves which may account for reports of salt induced thickness increase in leaves*

Mots clés : Kidney bean — Physiology. ; Plants — Effect of salt on.
