Níveis de alumínio e o desenvolvimento de porta-enxertos cítricos em cultivo hidropônico: I. Parâmetros biométricos

Abstract: O presente trabalho teve como objetivo avaliar a influência de diferentes níveis de alumínio nos parâmetros biométricos dos porta-enxertos cítricos limoeiro Cravo e citrumeleiro Swingle em cultivo hidropônico. O experimento foi instalado em casa de vegetação em Botucatu, SP. Os tratamentos seguiram o delineamento estatístico inteiramente casualizado, com 3 repetições, em parcelas subdivididas. Os níveis de alumínio utilizados foram: 0; 7,5; 15; 22,5 e 30 mg L-1, na forma de AlCl3 6.H2O em solução nutritiva. Fo… Show more

“…Pinto (1999) also verified that a 370 µmol L -1 Al concentration in the nutrient solution, can cause an increase in RSDMR for several citrus rootstocks. On the other hand, according to data presented by Santos et al (1999), the presence of aluminium did not change this characteristic, both for the 'Rangpur' lime and the 'Swingle' citrumelo.…”

“…Clune & Copeland (1999) observed maximum growth of canola roots in the presence of 40 µmol L -1 Al in the nutrient solution, due to an increase in size and number of cells; at higher concentrations, root growth inhibition occurred. In addition, according to Santos et al (1999), the root system length in 'Rangpur' lime seedlings exposed to 277 µmol L -1 Al, for 84 days, decreased 21% relative to the control. In 'Swingle' citrumelo, however, it decreased 49%.…”
