Phenotypes of Carazinho, EGA-Burke, and their F1 progeny. RRL (A) was calculated from net root growth after 4 d in 0 and 30 μm Al (n = 7). To account for the accumulation of errors associated with deriving RRL, the errors were calculated as follows: seRRG = RRG [(sex/x)2 + (sey/y)2]1/2, where x and y represent the mean net root length in the control treatment and the mean net root length in the Al treatment. Malate (B) and citrate (C) efflux from excised root apices were measured in the presence of 50 μm Al. Data show the mean and se (n = 3).
