Abstract

Celery plants (Apium graveolens L.) were placed in darkness for 18 days and the collenchyma cells of the petioles of these plants were subjected to acid hydrolysis and qualitative and quantitative analyses to determine the effect of prolonged dark treatment on the metabolism of the wall components. Chromatographic separation and spectrophotometric measurement of the amounts of sugars present after 18 days of treatment indicated a great reduction in amounts of galactose and arabinose, a smaller reduction of mannose and xylose, and no reduction of glucose. The changes reported are attributed to a possible metabolic turnover of wall materials brought about by the low carbohydrate level which existed under the experimental conditions. The role of the plant cell wall in the general metabolism of the cell is briefly discussed.
