摘要白潜蝇Miconia albicans（Sw.）在巴西中部塞拉多地区的酸性砖红壤上自然生长的Triana是一种铝积累灌木，在盆栽试验中在强酸营养不良土壤、强酸廊道森林土壤和石灰性土壤中生长。在酸性土壤中生长较好，而在营养不良土壤中生长较差。它们未能在石灰性土壤中生长，在第一对绿色叶子出现后，只产生一对泛黄、坏死且铝浓度较低的叶子。从石灰性土壤中移植到酸性土壤中的具有黄化叶的植物显示出黄化叶的完全恢复和伴随的叶中Al浓度的增加。植物生长在石灰性土壤中的褪绿叶也表现出完全恢复时，他们的根系的一部分，在氯化铝。含10 mg Al L-1的溶液。结果表明，植物生长在廊道森林土壤中，移植到石灰性土壤中，其生长量明显减少。
Abstract Seedlings of Miconia albicans (Sw.) Triana, an aluminum‐accumulating shrub, which grow naturally on acid latosols of the cerrado region of central Brazil, were grown in a strongly acid dystrophic soil, a strongly acid gallery forest soil and a calcareous soil in a pot culture experiment. The seedlings grew better in the fertile acid soil than in the dystrophic soil. They failed to grow in the calcareous soil, producing only a single pair of yellowed, necrotic leaves with low Al concentration after the emergence of a first pair of green leaves. Plants with chlo‐rotic leaves, transplanted from the calcareous to the acid soils, showed complete recovery of chlorotic leaves and a concomitant increase in the Al concentration in leaves. Plants growing in the calcareous soil with chlorotic leaves also showed complete recovery when parts of their root systems were grown in an AlCl3. solution containing 10 mg Al L‐1. Plants grown in gallery forest soil, when transplanted to the calcareous soil, showed redu...
