Plantago maritima grown under saline conditions accumulates large quantities of sodium chloride. Salinity reduces tissue potassium, calcium and magnesium contents. Several enzymes from P. maritima are shown to be salt-sensitive. In contrast to many other higher plant halophytes, P. maritima shows no accumulation of either amino acids or methylated onium compounds. High levels of the polyhydric alcohol sorbitol are however accumulated under saline conditions. The possible role of sorbitol as a compatible cytoplasmic solute is discussed.
在盐胁迫条件下生长的滨海车前草会积累大量氯化钠。盐分降低了组织中钾、钙和镁的含量。滨海车前草的几种酶显示对盐敏感。与许多其他高等植物盐生植物不同,滨海车前草既不积累氨基酸也不积累甲基化铵化合物。然而,在盐胁迫条件下会积累高水平的多元醇山梨醇。本文讨论了山梨醇作为一种相容性细胞质溶质的可能作用。
