Aluminum tolerance in maize: Minimizing ph changes in screening solutions1

Abstract

Preliminary screening of maize (Zea mays L.) genotypes for aluminum (Al) tolerance in nutrient solutions over a 12-day growth period showed greater plant-induced pH changes in solutions without Al than in solutions containing Al. Such pH changes may alter the specific effect of Al on relative root length (length in Al-containing solution/length in 0 Al solution) commonly used as an index to rank genotypes with respect to Al tolerance. The objective of this study was to examine several. © 1990, Taylor & Francis Group, LLC. All rights reserved.
