Aluminium, a metallic element abundant in soils as aluminosilicates minerals, poses a toxic threat to plants, particularly in acidic soil conditions, thereby affecting their growth and development. Given their adaptability to diverse soil and climate conditions, plants have gained significant attention regarding their tolerance to Aluminium toxicity. In the North-eastern region of India, where soils are often slightly acidic with elevated aluminium levels, species are predominantly found. Understanding the tolerance mechanisms of these fruits and screening wild species for their adaptability to abiotic stresses is crucial for enhancing fruit production. Numerous investigations have demonstrated that species exhibit remarkable tolerance to aluminium contamination, surpassing the typical threshold of 30% incidence. When cultivated in acidic soils, plants encounter restricted root growth and reduced nutrient and moisture uptake, leading to various nutrient deficiency symptoms. However, promisingly, certain species such as (Rough lemon), , , and have shown considerable aluminium tolerance. This comprehensive review delves into the subject of aluminium toxicity and its implications, while also shedding light on the mechanisms through which plants develop tolerance to this element.
铝作为铝硅酸盐矿物在土壤中大量存在的一种金属元素，对植物构成毒性威胁，尤其是在酸性土壤条件下，从而影响植物的生长发育。鉴于植物对多种土壤和气候条件的适应性，它们对铝毒性的耐受性受到了广泛关注。在印度东北部地区，土壤通常呈微酸性且铝含量较高，主要发现了一些物种。了解这些水果的耐受机制并筛选野生物种对非生物胁迫的适应性对于提高水果产量至关重要。大量研究表明，某些物种对铝污染表现出显著的耐受性，超过了30%发生率的典型阈值。当种植在酸性土壤中时，植物会遇到根系生长受限以及养分和水分吸收减少的情况，从而导致各种养分缺乏症状。然而，令人欣慰的是，某些物种，如粗柠檬、[此处原文缺失具体物种名]、[此处原文缺失具体物种名]和[此处原文缺失具体物种名]，已表现出相当强的铝耐受性。这篇综述深入探讨了铝毒性及其影响的主题，同时也阐明了植物对该元素产生耐受性的机制。
