Growth, heavy metal uptake, and photosynthesis in 'Paulsen 1103' (Vitis berlandieri x rupestris) grapevine rootstocks inoculated with arbuscular mycorrhizal fungi from vineyard soils with high copper contents

摘要: Soils in old vineyards southern Brazil have high copper accumulation due to fungicide applications over the years, which can affect physiology and growth of young grapevine plants. Arbuscular mycorrhizal fungi (AMF) alleviate toxic effects metals increase photosynthesis plant growth. We evaluated whether inoculation with Rhizophagus clarus (Rh) from a mining area or trap-culture-enriched AMF community (Tc) isolated high-copper vineyard soil, improved rootstocks planted ( 60 years) soils Vale da Uva Goethe, SC, Brazil. Mycorrhizal colonization was higher grapevines installed soil than those soil. Plants grew more vineyard, that related nutrient concentration In both soils, Tc-inoculated had photosynthetic activity, while inoculated R. carbon assimilation. conclusion, showed positive response different conditions, native are promising for grapevines.
