“…The dominant Al in acidic soil inhibits root growth, damages the root tip cells (Ryan et al, 1993;Kochian, 1995;Brunner and Sperisen, 2013), the absorption of essential nutrients, and cell division (Marschner, 1992: Hanum et al, 2007. Inhibited cell division of plant is caused by the Al toxicity on the cell wall and it disrupts mitotic activity.…”

Aluminum (Al) contained in acidic soil could become an obstacle for plant growth. The Al toxicity could inhibit root growth, water and nutrient absorption. One of the solution to overcome Al toxicity was by applying Silica (Si). The aim of this research was to study the impacts of Al to the growth activity of oil palm and to know the effects of Si to the growth activity of oil palm contaminated by Al. The factorial treatments were arranged in a complete random design with two factors. The first factor was Al toxicity, i.e. with and without Al, while the second factor was the application of Si that consisted of four levels (0, 32, 64, 96 gram per plant). some of variables included leaf area ratio (LAR), leaf area, net assimilation rate (NAR), relative growth ratio (RGR), plant height, and plant dry weight were observed. The result showed that Al toxicity decreased the LAR, leaf area, NAR, RGR, plant height, and plant dry weight. The application of Si 32 gram per plant increased leaf area ratio and was not significantly different from the application of 96 gram Si per plant. However, the application of Si to oil palm contaminated with Al did not affect to relative grow rate, but its application to normal plant would increase the relative growth ratio.

“…In the soil, soluble Al (Al 3+ ) is toxic to most crops, causing physical damage to cell walls (Horst et al 2010) and root tips (Kopittke et al 2008). Chelation and/or exclusion of Al at the root tip seem to be critical strategies for avoiding Al in crop plants (Ryan et al 2011) and native species (Brunner and Sperisen 2013).…”

The cerrado's flora comprises aluminum-(Al) accumulating and non-accumulating plants, which coexist on acidic and Al-rich soils with low fertility. Despite their existence, the ecological importance or biological strategies of these functional groups have been little explored. We evaluated the leaf flushing patterns of both groups throughout a year; leaf concentrations of N, P, K, Ca, Mg, S, Al, total flavonoids and polyphenols; as well as the specific leaf area (SLA) on young and mature leaves within and between the groups. In Al-accumulating plants, leaf flushed throughout the year, mainly in May and September; for non-accumulating plants, leaf flushing peaked at the dry-wet seasons transition. However, these behaviors could not be associated with strategies for building up concentrations of defense compounds in leaves of any functional groups. Al-accumulating plants showed low leaf nutrient concentrations, while non-accumulating plants accumulated more macronutrients and produced leaves with high SLA since the juvenile leaf phase. This demonstrates that the increase in SLA is slower in Al-accumulating plants that are likely to achieve SLA values comparable to the rest of the plant community only in the wet season, when sunlight capture is important for the growth of new branches.

“…Exposure to Al generally results in a severe reduction in growth and productivity due to the inhibition of root cell division and elongation and reductions in the uptake of water and assimilation of nutrients including N, P, Ca, and Mg. Certain plant families show an innate tolerance to acidic soils and Al [1] and some trees species are thought to resist elevated soil metal concentrations by means of a large phenotypic plasticity [2]. For many tree species, however, symbioses with a small guild of well-adapted ectomycorrhizal (ECM) fungi reduce the sensitivity of roots and plants to Al stress [3].…”

Aluminum-TolerantPisolithusEctomycorrhizas Confer Increased Growth, Mineral Nutrition, and Metal Tolerance toEucalyptusin Acidic Mine Spoil

Ectomycorrhizal fungi (ECM) may increase the tolerance of their host plants to Al toxicity by immobilizing Al in fungal tissues and/or improving plant mineral nutrition. Although these benefits have been demonstrated in in vitro (pure culture) or shortterm nutrient solution (hydroponic) experiments, fewer studies have examined these benefits in the field. This study examined the growth, mineral nutrition, and Al levels in two Eucalyptus species inoculated with three Pisolithus ecotypes that varied in Al tolerance (in vitro) and grown in mine spoil in the greenhouse and field. All three ecotypes of Pisolithus improved Eucalyptus growth and increased host plant tolerance to Al in comparison to noninoculated plants. However, large variations in plant growth and mineral nutrition were detected among the Pisolithus-inoculated plants; these differences were largely explained by the functional properties of the Pisolithus inoculum. Seedlings inoculated with the most Al-tolerant Pisolithus inoculum showed significantly higher levels of N, P, Ca, Mg, and K and lower levels of Al than seedlings inoculated with Al-sensitive ecotypes of Pisolithus. These findings indicate an agreement between the fungal tolerance to Al in vitro and performance in symbiosis, indicating that both ECM-mediated mineral nutrient acquisition and Al accumulation are important in increasing the host plant Al tolerance.
