Abstract

Alleviation of Al toxicity by Ca and Mg was studied with seedings of Pinus densiflora, P. rigida and P. thunbergii under the solution culture. The seedlings were cultivated in the enriched Can and Mg nutrient solution with 2, 000 ${\mu}M$ Al for three weeks. The hightest total root lengths of P. densiflora, P. rigida and P. thunbergii increased by 21, 33 and 133% in Ca enriched solution, and 23, 44 and 107% in Mg enriched solution, respectively. Ratios of lateral root to main root length increased significantly in Mg enriched solution, and redution of Al toxicity was more affected by enriched Mg than by enriched Ca. Al content in tissue was reduced by enriched Ca and Mg.
