Abstract:
The refractive index and electrical conductivity of the leaf sap of two citrus species, sour orange and sweet lime, were measured at different soil-moisture levels. Their osmotic potentials contributed by electrolytes and soluble metabolites were estimated. The sum of these two estimates agreed fairly well with the total osmotic potential of the leaf sap as measured by cryoscopy. The results indicate that the refractometry-conductimetry method is adequate for studying the changes of osmotic potential of citrus seedlings during the course of irrigation cycles. © 1968 OXFORD UNIVERSITY PRESS.
