“…On the other hand, in 300 µM Al-treated root, the diameter of metaxylem vessels was increased (Plates 2 and 3). Similarly, due to 300 µM L -1 Al, Batista et al (2012) found that, in the vascular bundle, the metaxylem and protoxylem had no secondary walls and their diameter was much smaller compared to that of control plants. This study demonstrated that higher concentration of Al caused structural impairment.…”

“…In Al-treated root, the cortical cells presented a higher amount of intercellular space and its cells were elongated longitudinally (Plates 2 and 4). According to Batista et al (2012), due to 75 and 300 µmol L -1 Al treatment in maize root, the cortical parenchyma cells consisted of prominent intercellular spaces, which was a form of adaptation. Sclerenchymatous layer was uniserate both in control and 150 µM Al treated plant but biseriate in 300 µM Al-treated plant (Plate 4).…”

“…Plants respond to various stresses through morphological, anatomical and physiological adjustments that help them to cope with the stress. The size of protoxylem and metaxylem vessels were smaller and showed deformed appearance in maize plant after aluminium treatment (Batista et al 2012). Due to Al exposure, reduced length was found in the meristematic and elongation zones of barley root (Kochian 1995).…”

Anatomical response of rice (Oryza sativa L.) to aluminium toxicity grown in sand culture and half strength Hoagland solution revealed that aluminium stress caused a decrease in diameter of the root and the shoot. Aluminium toxicity reduced the number of metaxylem vessels in the root of rice. Number of sclerenchyma cells was more in aluminium-treated rice root. Under Al stress, smaller sized vascular bundles were found in the leaf of rice. Size and frequency of bulliform cells were increased in the leaf of Al-treated plants than that in control plants. Al treatment caused closure of stomata in rice leaves.

“…This could be attributed to the limitation on nutrient absorption by plants when Al was present in the soil at toxic levels. The main symptom of Al toxicity in differents plants was rapid root growth inhibition caused by different mechanisms, such as interactions of Al 3+ with the cell wall and plasma membrane, callose production, and damage to the apoplast (MA et al, 2004, BATISTA et al, 2013.…”

The aluminum in high levels in the soil affects the emergence, growth, and development of various species. Therefore, the objective of this study was to evaluate the emergence and physiological behavior of four provenances of Jatropha curcas subjected to different levels of aluminum. The experiment was performed in a greenhouse in a completely randomized design, with four levels of aluminum in the soil (8.2, 16.5, 24.0 mmolc·dm-3 and control) and four provenances of J. curcas seeds (P1 = Dourados-MS, P2 = Montes Claros-MG, P3 = Alta Floresta-MT, and P4 = Petrolina-PE); the effects of aluminum toxicity were investigated in 25, 50, 75, and 100 days after emergence. The levels of aluminum in the soil were collected from the initial soil correction, which featured an aluminum level of 24.0 mmolc dm-3. The seedling emergence was not affected by treatment with aluminum; however, the height and leaf area of P1, P2, and P3 were reduced with increasing levels of aluminum. The emergence and vigor of J. curcas seeds were not influenced by the differences in the origins of the seeds or by the aluminum levels evaluated. Gas exchanges were affected negatively by aluminum and the responses of the chlorophyll a fluorescence indicate harmful effect in the photosynthetic apparatus. The seeds of origin P4 (Petrolina-PE) has increased tolerance to stress conditions.

“…More than 30% of the world's soils are classified as acidic (FAO, 2015), while more than 50% of the agricultural land is acidic (pH ≤ 5.5). The Al +3 ions absorbed by plants are predominantly present in their root systems because they perform their growth inhibitory function in the root elongation zone (Batista et al, 2013). Aluminum may interfere with the polar transport of auxins, mainly affecting the formation of lateral roots that are important for nutrient uptake.…”

Stress by salt and aluminum (Al+3) causes significant loss in the growth of popcorn. Effects on the initial growth, especially of leaves and stomata, are poorly investigated, while no information is available for some cultivars. This work aims at verifying the effect of stress caused by salt and Al+3 on the initial growth, morphometry, and morphology of popcorn stomata (IAC-125), as well as on its foliar anatomy. In the presence of 50 mM or higher concentrations of NaCl, popcorn seedlings showed a reduction of 50% in shoot mass gains as compared to the control. With 150 mM or higher concentrations, mass gains reduced by 33% in popcorn root system as compared to the control. Small increases in shoot length were observed in seedlings treated with Al+3.The root system was highly affected by 160 µM or higher Al+3 concentrations. Pore opening and stomatal subsidiary cell width were altered under both salt and Al+3 stress. Stomatal density changes were observed only under salt stress. Tissue disruptions and cell numberreductions were verified in the epidermis and parenchyma under high Al+3 and saltconcentrations. The largest xylem and phloem cells were preserved in all treatments. Stress resulted in dehydration of plant tissues, which showed retraction under high concentrations of salt and Al+3due to anatomical changes in the leaves and morphometry of the stomata. Our results demonstrated that these characteristics contributed to a remarkable tolerance to salinity and aluminum, since they have an important protective role against different environmental stresses.
