“…The nutrient solution shows a chemical composition based on Clark's solution (Clark, 1975) that has been used to test Al resistance in Citrus rootstocks (Santos et al, 2000 Silva et al, 2012). The pH of the solution was maintained at 4.0 ± 0.1 in order to keep the Al as soluble as possible.…”

Aluminum (Al) is toxic to most plants. Although inhibition of root elongation can occur even under 10 M Al, above 1000 M damage to photochemical performances has been reported, reducing the CO 2 assimilation rate (A). However, Al is retained in the roots of most plants, including Citrus limonia ('Rangpur' lime) with no direct explanation for the low A. In this study, 'Rangpur' lime plants were cultivated hydroponically in a nutrient solution with 1480 M Al, and we expected to determine the time range within which Al-induced decrease in A starts. To our surprise, low stomatal conductance (gs) rather than low photochemical performances was evident 45 days after exposing the roots to Al. Aluminum was mostly retained in the roots and histochemically observed in the stele, suggesting reduction in water uptake/transport in the xylem that became fibrous. We also found a 35% reduction in the midday leaf water potential in plants exposed to Al, indicating association between the fibrous xylem vessels and low gs, which could explain the Al-induced decrease in A in 'Rangpur' lime plants.

“…We used a nutrient solution (Furlani and Furlani 1988) with a chemical composition based on Clark's solution (Clark 1975) that has been used to study Al toxicity in Al-sensitive tree species (Santos et al 2000). However, we diluted its macro-and micronutrient concentrations by seven in order to resemble the nutrient composition of Cerrado soils (Habermann and Bressan 2011;Souza et al 2015b).…”

In the Cerrado vegetation, generally known as 'Brazilian savanna', aluminum (Al) accumulating and non-accumulating plants coexist, growing on soils that are acidic, poor in nutrients and rich in Al. Differing from Al-sensitive species, these plants are not expected to experience Al injuries. Using Styrax camporum, a non-accumulating plant, we recorded biometric variations in leaves, shoots and roots of young plants exposed to 0 and 1480 lM Al in a nutrient solution. Photosynthetic responses were measured biweekly over 91 days. Plants exposed to Al drastically reduced flushing, indicating that Al interferes with the functioning of the shoot apex. Aluminum caused low CO 2 assimilation rate, largely explained by low stomatal conductance, while Al-induced decrease in photochemical performance occurred only on some dates during the experiment. In addition, the absorbed Al was mostly retained in the roots. Although counterintuitive, as this species grows on Al-rich soils, we noted that high Al availability impairs lateral root formation, causing an impact on water uptake and gas exchange rates of this species.

Al treatment decreased leaf, stem, and root fresh and dry weight of "Cleopatra" tangerine ( Citrus reshni Hort. ex Tan.) seedlings, but increased leaf dry weight per area. Leaf and stem fresh and dry weight decreased to a greater degree than root fresh and dry weight in response to Al and resulted in a Abstract Aluminum (Al) toxicity is the major factor limiting plant growth in acidic soils, which comprise up to 50% of the world's potentially arable lands. Citrus belong to evergreen subtropical fruit trees and are cultivated in humid and subhumid of tropical, subtropical, and temperate regions of the world mainly on acidic soils. Soil acidi fi cation is a major problem in citrus plantations. There has been signi fi cant progress in our understanding of the physiological responses and the tolerance of citrus to Al toxicity during the past decade. In this chapter, growth, physiological responses (carbohydrates, photosynthesis, water relation, light energy utilization, photoprotective system, mineral nutrients, and organic acids), and tolerance (genotypic differences, Al uptake, and distribution, and Al-induced secretion of organic acid anions) of citrus to Al toxicity are reviewed. The amelioration of phosphorus (P) and boron (B) on citrus Al toxicity as well as some aspects needed to be further studied are also discussed.
