Elements sequestered by arbuscular mycorrhizal spores in riverine soils: A preliminary assessment
The elemental composition of spore wall of arbuscular mycorrhizal fungi (AMF) was analyzed by energy-dispersive X-ray spectrometry (EDS) in a preliminary assessment. Measurements of AMF spores were made for riparian soils in both urban (rivers subjected to different human activities) and farm sites in southeastern Brazil. Spore populations belonging to four...

Influence of gibberellic acid and arbuscular mycorrhizae inoculation on carbon metabolism, growth, and diterpene accumulation in Taxus wallichiana Zuccarini var. mairei
Changes in growth parameters and 14C02 and [U-14C]-sucrose incorporation into the primary metabolic pools and diterpene 10 DAB compound were investigated in leaves and stems of Taxus wallichiana Zucarnii treated with gibberellic acid (GA) and inoculated with arbuscular mycorrhizae (AM). Compared to the control, GA(1000 ppm) and AM (1 kg/ha each) with AM-GA combined treatments, induced...
