摘要: Crop nutrient- and water-use efficiency could be improved by using crop varieties highly compatible with arbus- cular mycorrhizal fungi (AMF). Two greenhouse experiments demonstrated the presence of genetic variability for this trait in modern durum wheat (Triticum turgidum L. var. Desf.) germplasm. Among five cultivars tested, 'AC Morse' had consistently low levels AM root colonization DT710 high colonization, whereas 'Commander', which highest under soil fertility conditions, developed poor coloni- zation medium level. The compatibility AMF was further evidenced significant genotype × inoculation interaction effects grain straw biomass production; P, K concentrations level; Fe at fertility. Mycorrhizal dependency an undesirable 'Mongibello', showed growth nutrient balance absence AMF. An AMF-mediated reduction Cd indicated that breeding help reduce concentration wheat. Durum genotypes should selected rather than dependency.
