Abstract
A sand culture system was used to compare growth reduction in Prunus rootstocks due to high A1 concentration. Aluminum at 50 mg liter-1 nutrient solution resulted in A1 tissue levels of 288 to 408 mg.kg-1, shoot growth reduction of 41% to 77%, and root growth reduction of 9% to 86%. Based on relative growth reduction, Prunus tomentosa Thunb. was more sensitive to A1 toxicity than were Nemaguard, Nemared, ‘Lovell’ [P. persica (L.) Batsch], P. besseyi Bailey, P. cerasifera Ehrh., and P. insititia L. Nemaguard and P. tomentosa had higher shoot A1 concentration at 50 mg Al/liter than the other rootstocks tested.
