Pea seeds were soaked in distilled water or in saturated D‐mannitol solution either under normal or under high external pressures (10‐30 atms.) for approximately 24 hours. Imbibition in distilled water was independent of the hydrostatic pressure. However, imbibition in D‐mannitol solution was enhanced by the pressure. It was concluded that hydrostatic pressure caused by turgor could enhance imbibition of the protoplast. Under high turgor, the protoplast may swell even at a high osmotic potential. Turgor seems to be of importance for the physiological activity of the plant cell.
