INTERACTION OF ALUMINUM AND CALCIUM ON NEMAGUARD PEACH SEEDLING NUTRIENT CONTENTS AND GROWTH IN SAND CULTURE Academic Article uri icon

abstract

  • Cultivar 'Nemaguard' peach (Prunus persica (L.) Batsch) seedlings were grown in sand culture with 0, 25, 50, 75, 100 or 125 mg 1-1 Al in nutrient solution. High Al concentrations decreased shoot Ca, Zn, Cu, Fe and Mo, but did not affect shoot Mg, K and Mn. Root Ca, K, Mo, Zn and Cu were also reduced, but Mn and Fe were not. In a factorial experiment with Al concentrations of 0, 50 and 100 mg 1-1 and Ca concentrations of 0, 50 and 100 mg 1-1, Al toxicity decreased shoot and root dry weights, shoot length, number of branches, stem caliper and number of leaves. Ca had no effect on the response to Al at 0 and 100 mg 1-1 Al, but had an ameliorating effect on toxicity at 50 mg 1-1 Al. Ca reduced Al accumulation and Al reduced Ca accumulation in the shoot. 1990.
