“…Veloso et al (1995), studying black pepper, observed this positive effect for leaf biomass caused by aluminum in concentrations up to 15 mg L -1 . This was also described by Salvador et al (2000), in guava seedlings, with positive effects on plant height and leaf area at concentrations below 10 mg L -1 . The explanation for that fact is that, even though aluminum is not considered an essential element for plants, low concentrations can stimulate the growth of some plant species (Ferreira et al, 2006).…”

Aluminum toxicity effect on the initial growth of yacon plantlets

et al. 2018

The increasing consumption of yacon potato has raised worldwide interest in its crop and generated demand for scientific elucidations of several factors associated to its agricultural management. Among the demands, there are the studies related to the effects of aluminum (Al3+) on the development of yacon plants. Thus, this study was developed to evaluate the effects of aluminum on budding and initial growth of yacon plantlets. The experiment was carried out in a completely randomized block design, with three replications and six aluminum contents in the substrate: 0, 10, 25, 50, 100, and 200 mg L-1. The response of yacon plantlets to aluminum contents was evaluated by the emergence time, emergence speed index, number of leaves, plant height, leaf area, radicle length, and dry mass weight of leaves, stems, and radicles. The presence of aluminum in the substrate negatively influences the emergence and initial growth of yacon, causing losses in foliage development (number of leaves and leaf area), in biomass accumulation, growth and, especially, restricting the development of radicles. Aluminum toxicity fully inhibits radicle growth in substrate contents above 83 mg L-1, under the controlled conditions used in this experiment.

“…1A). Salvador et al (2000) showed that, when the Al in the nutrient solution ranged from 5 to 10 mg kg -1 , the growth and development of the guava plants were higher than in the control (without Al) and when the Al concentrations ranged from 20 to 25 mg kg -1 . The increase in the shoot and dry matter production in the Al 25 to 50 mg kg -1 doses could partially be explained by the steady and increasing P availability by the AP source which protected the cell's membrane against the Al toxic actions.…”

“…Este resultado é semelhante ao obtido por Malavolta et al (1981) em que o uso de solução nutritiva com alta concentração de alumínio (440 μM) permitiu boa discriminação entre híbridos de sorgo tolerantes e suscetíveis. Salvador et al (2000) observaram em solução nutritiva que concentrações de Al 3+ abaixo de 10 mg.L -1 aumentaram a altura da planta e a área foliar em mudas de goiabeira (Psidium guajava L.), respectivamente, aos 30 e 90 dias de cultivo.…”

RESUMO -Dentre todas as fruteiras de clima temperado, a macieira é a que mais atenção tem recebido no sentido de se obterem portaenxertos com características de boa adaptação, resistência ou sanidade. O desenvolvimento de um método eficiente para caracterizar genótipos com tolerância ao alumínio é o primeiro passo para a realização de estudos de mecanismos genéticos envolvidos na herança desse caráter. Assim, o presente trabalho teve por objetivo avaliar a tolerância ao alumínio dos porta-enxertos de macieira M.9 e Marubakaido em cinco concentrações (0; 50;150; 250 e 350 μM L -1 ) em solução nutritiva. As estacas de Marubakaido, na concentração intermediária de alumínio apresentaram menor crescimento radicular e aéreo. O M.9 mostrou menor crescimento radicular nas concentrações de 250 e 350 μM de alumínio. As características de crescimento avaliadas permitiram discriminar o porta-enxerto Marubakaido como mais tolerante que o M.9, e a concentração de 350 μM L -1 é a mais eficiente para a discriminação da tolerância ao alumínio aos 15 dias de cultivo em solução nutritiva. Termos para indexação: Malus sp, melhoramento genético, tolerância ao alumínio. ESTABLISHMENT OF CRITERIA TO SELECT APPLE TREE ROOTSTOCKS TOLERANT TO THE ALUMINUM IN NUTRITIOUS SOLUTIONABSTRACT -Among all of the temperate fruit trees, the apple tree is the one that has attracted more attention when it comes to obtaining rootstocks with characteristics of good adaptation, resistance or sanity. The development of an efficient method to characterize genotypes with tolerance to the aluminum is the first step for the accomplishment of genetic mechanisms studies involved in the inheritance of this character. Thus, the present work aimed to evaluate the tolerance to aluminum of the apple tree rootstocks M.9 and Marubakaido in five concentrations (0, 50, 150, 250 and 350 μM L -1 ) in nutritious solution. The cuttings of Marubakaido, in the intermediate concentration of aluminum presented smaller root and aerial growth. M.9 showed smaller root growth in the concentrations of 250 and 350 μM of aluminum. The evaluated growth characteristics permitted to identify the apple rootstock Marubakaido as more tolerant than the M.9, and the concentration of 350 μM L -1 is the most efficient to identify the tolerance to aluminum in the 15 days of cultivation in nutritious solution. It is expected that later, this data can be used in works of individuals' selection in segregated populations accomplished in crossings with these two apple rootstocks.
