Abstracts |
Studies were conducted to analyse the effects of Glomus intraradices and G. mosseae on the growth and nutritional status of seedlings of sour orange. Sour oranges inoculated with the arbuscular mycorrhizal fungi (AMF) had significantly higher fresh and dry weight of leaves, stems and roots than those not inoculated. The number of leaves, plant height and stem diameter were also greater, indicating that the AMF used accelerated the development of the plants. The AMF inoculation significantly increased the concentration of phosphorus in the plants compared to uninoculated plants, whereas decreased levels of nitrogen, Ca2+, Na+, K+ and Mg2+ were observed. This effect was possibly due to a dilution of nutrients produced by the further growth of these plants. Furthermore, the presence of AMF significantly increased leaf chlorophyll levels, although levels of iron in leaves were not altered. There were no significant differences in the behaviour of plants inoculated with the 2 AMF types, except for leaf number, fresh weight and phosphorus concentration on the same leaf. These results showed that inoculation with AMF could be a useful tool to accelerate the growth of sour orange. These fungi could be used as biofertilizers in the cultivation of citrus seedlings. |
