FUNCTIONING OF VESICULAR–ARBUSCULAR MYCORRHIZAS UNDER FIELD CONDITIONS

摘要: Summary Although VA mycorrhizas are easily demonstrated as mutualistic associations in pot culture, on the basis of reciprocal exchange carbon and (mainly) phosphorus, unequivocal field demonstrations less numerous. This may be due to incompetence widely occurring fungal types, inter-plant connections by hyphae, which dissipate benefit, grazing external or problems associated with root longevity. The action mycorrhizal roots improving plant water relations promoting phosphate uptake under conditions is considered light these constraints. It suggested that much greater effort required investigation field.
