Development of Soluble and Insoluble Invertase Activity in Washed Storage Tissue Slices

Abstract
The ratio of soluble to cell wall invertase in Beta vulgaris, Daucus carota, and Solanum tuberosum varied according to the tissue. The activity of aged disks was approximately equal to the cell wall invertase, whereas the activity of aged disks with treated ethyl acetate prior to assay was equal to the sum of the cell wall and soluble invertases.
