Effect on nutrient acquisition of Eucalyptus urophylla inoculated with Glomus and/or Pisolithus

This paper reports the influence on nutrient uptake of Eucalyptus urophylla seedlings 5 months after inoculation with Glomus and Pisolithus isolates alone or in competition in a nursery. Though concentrations of some mineral elements in roots or tops varied according to different fungal treatments, there was a substantial increase of nutrient amount of all elements in inoculated seedlings. Phosphorus content in inoculated seedlings were 2.67 to 2.88 times of the uninoculated ones. The total content of N, K and B in the inoculated seedlings was respectively 3.58-7.00, 2.65-3.18 and 2.78-3.88 folds of those of the uninoculated ones. The results showed that inoculation with Pisolithus and/or Glomus isolates affected nutrient uptake and their distribution in parts of seedlings. The two fungal isolates also influenced the acid phosphatase activity in roots
