Fig. 6From: A new allele for aluminium tolerance gene in barley (Hordeum vulgare L.)Comparison of Al tolerance of two parental varieties grown in acid soil (pH = 4.3) by root length and damages to root tips. Root length was compared between (a) CXHKSL and (b) Gairdner. Typical root apices from an Al-tolerant genotype is shown in (c) and typical root apices from a sensitive genotype with obvious thickening and damage is show in (d)Back to article page
