An analysis of the frequency of occurrence of chloroplasts, mitochondria and microbodies in leaf cells of the halophyte Sueda maritima (L.) Dum, showed a remarkable increase (almost a doubling) in the number of mitochondria per cell section when plants were grown in saline (340 mol m −3 NaCl) as opposed to non‐saline conditions. Chloroplast and microbody volume per cell increased under saline conditions, but number per cell was insensitive to salt. Chloroplasts contained a greater number of starch grains in plants grown under saline as compared to non‐saline conditions and, under both conditions, were closely associated with the cell wall adjacent to the intercellular spaces. The implications for growth, photosynthesis and respiration are discussed.
