Abstract

The elongation zone of the primary root of barley (Hordeum vulgare L.) has been reported to be markedly basic in pH, in apparent contradiction of the acid-growth theory. We determined simultaneously the location of the elongation zone and the basic zone in these roots and found them indeed to be the same. However, sections of barley root elongation zones were found to respond to acidic, basic, and neutral solutions as predicted by the acid-growth theory.
