“…The results found in P and K levels corroborate those reported by Mello (2006) , where there was no significant difference in the levels of these elements, working with the same experiment in Entisol, and by Silva et al (2003) , which also found no phosphorus accumulation in inoculated seedlings, working with Pinus elliottii Engelm in sandy soil.…”

Eucalypts is one of the main species used for commercial reforestation in the Rio Grande do Sul State, Brazil. This study aimed to evaluate the survival and early growth of eucalyptus trees in an area subject to sandy process after three years of growth. The Eucalyptus grandis seedlings were grown in a greenhouse, inoculated or not with the isolated ectomycorrhizal Pisolithus microcarpus (UFSC-Pt116), produced in peat or Entisol. After 120 days, the seedlings were transplanted to an area subject to the sandy process, in the São Francisco de Assis city, RS. The plants have been evaluated regarding survival, height, stem diameter, nitrogen, phosphorus and potassium levels and total phosphorus, inorganic phosphorus, organic phosphorus and wood production on different days after planting. The seedlings grown on the Entisol which was inoculated with the isolated UFSC-Pt116 presented higher survival rates, height, stem diameter, nitrogen concentration and wood production then non-inoculated seedlings. Inoculation with ectomycorrhizal fungi enhanced the production of E. grandis seedlings in survival rates, height, stem diameter.

“…The increase in the surface area of absorption of the roots represents an increase in the volume of exploited soil, and according to Harley (1969), the surface area exploited by ectomycorrhizal fungi is estimated to be 1,000 times greater than that of roots without the presence of ectomycorrhiza. Mycorrhizal plants could have a better nutritional status compared to plants without inoculation, which could be a conditioning factor for the survival rate of the species (Silva et al, 2003). These results show a positive effect of the UFSC-PT116 isolate on the surface area of the roots of yerba mate seedlings subjected to Cu contamination.…”

Copper (Cu) is one of the main heavy metals contaminating the soil. Plants have different behavior in terms of tolerance and toxicity to metals, being able to grow and produce even in soils contaminated with high concentrations. This study aimed to determine the influence of ectomycorrhizal fungi on the growth and tolerance of yerba mate plants grown in soil contaminated with Cu. The design was completely randomized in a factorial arrangement (4x6), with four possibilities of inoculum: without inoculum (control) and three ectomycorrhizal fungi (UFSC-PT116 — Pisolithus microcarpus, UFSC-PT132 — Pisolithus tinctorius and UFSC-SU118 — Suillus cothurnatus), with six Cu doses amended to the soil (0, 80, 160, 240, 320 and 400 mg kg-1 of Cu) in seven replicates. The height of the aerial part, the diameter of the lap, the dry mass of the aerial part and root system, the leaf area, the specific surface area of the roots, the contents of Cu in the aerial and radicular parts, the tolerance index, and mycorrhizal association were assessed. Inoculation of Ilex paraguariensis seedlings with ectomycorrhiza fungi UFSC-PT116, UFSC-PT132, and UFSC-SU118 mitigates the toxicity effect caused by the excess of Cu in the soil. The UFSC-PT116 isolate promoted the highest growth and tolerance of Ilex paraguariensis seedlings under the treatments. In general, the isolates promoted the reduction of Cu toxicity in Ilex paraguariensis plants, being an important alternative to remediate Cu-contaminated areas.

“…indeed, the use of mycorrhizas to cultivate this species favors the development of seedlings (Silva et al, 2003). the analysis of variance indicated no significant difference in the stem diameter and height of the seedlings in each treatment, thus ruling out the possibility that these variables may have interfered in the results (table 1).…”

Pinus elliottii is a fast-growing conifer well adapted to southern Brazil, used for wood fiber and resin production. oleoresin production is part of the plant's defense systems and is induced by ethylene, which production is stimulated by hypoxic conditions. the experiment was designed with the goal of verifying whether one year-old plants had measurable oleoresin yield and if flooding led to increased oleoresin production. there was an increase of 78% in oleoresin production after 14 to 21 days of flooding and plants with larger stem diameters were more productive.
