Abstract:

A quantitative cytochemical study of Naphthol AS-D esterase activities on the frozen longitudinal and transverse sections of primary roots of Pisum sativum and Vicia faba has indicated the presence of high esterase activity (Carboxylesterases E. C. 3.1.1.) in the endodermis, stele, proendodermis and prostele, but low levels of esterases (Acetylesterases E. C. 3. 11.6. ) in the cortex and procortex. Endodermis appears to be closely related to stele rather than the cortex and there are common initials for endodermis and stele.
