Abstract
Field experiments were conducted to determine the effect of stage of maturity and season on the acidity of rhubarb petioles. Some physiological or biochemical changes with age of petioles were determined. The changes in petioles of similar age developed at different periods of the growing season were also determined. The effect of shading the plants with cheesecloth was studied. Acidity determinations indicated that the younger petioles were more acid than older ones. The soluble potassium content increased as the petioles aged. The acid content of the petioles was low at the beginning of the harvesting period but was significantly higher at the end. Petioles grown in full sunshine were more acid than those grown in partial shade.
