VARIATION OF THE QUANTITIES OF SOLUBLE COMPOUNDS IN EXPLANTS, CALLI AND SUSPENDED CELLS OF THE SAME LINEAGE
Systematic studies have been made on the contents of carbohydrate, organic acids, phenolic compounds, and proteins of apple fruit pericarp explants and of the calli and suspended cells derived from the explants. In the explants, while phenolic compounds and carbohydrate decreased sharply upon inoculation, organic acids and more evidently, soluble proteins tended to increase. The level of soluble compounds in the calli were quite different from those of the explant on which they developed: the most remarkable occured for the phenolic compounds. In the detached calli, phenolic compounds decreased steadily, carbohydrates decreased first then increased, total organic acids increased up to the 3nd inoculation then stabilized, and proteins remained constantly high. In a cell suspension, carbohydrates and organic acids increased then decreased; as the suspension aged, the level of phenolic compounds and of proteins increased. Some enzymes have also been studied.
