Aluminum toxicity effect on the initial growth of yacon plantlets
ABSTRACT 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.
