A new technique employing Sephadex G25 beeds containing a pH indicator dye (bromocresol purple), was used for measuring both the growth gradient of the roots (Sephadex beads as markers) and at the same time, the surface pH changes (referring to a standard scale). The opt. axial growth was located between 2 and 4 mm from the tip. This coincides with the opt. decrease in surface pH.Collection: Reprints Collection
