Abstract: Symbiotic associations between endophytic fungi and Chenopodium quinoa have been reported to be beneficial for increasing tolerance to drought and soil salinity, being this the only crop grown in the Southern Altiplano of Bolivia. The symbiotic interaction of endophytic fungi was investigated, considering their detrimental and mutualistic effects. 38 strains of endophytic fungi from the fungal collection of the Faculty of Agronomy were used. The percentage of germination and root length were measured in vitro (4 days). The percentage of emergence (7 days) and plant height (14 days) in pots were also evaluated. The fungi that did not impair germination were strains VP42, VP44, Alternaria sp. VP37, Fusarium sp. VP05 and Fusarium sp. VP30. Fungi that stimulated a significant increase in radicle longitudinal growth were Fusarium sp. VP35, Alternaria sp. VP37 and strain VP18. Fungi that caused a high mortality rate during the emergence phase were strain VP01, Alternaria sp. VP15, Fusarium sp. VP02, Fusarium sp. VP07, Fusarium sp. VP08, Fusarium sp. VP12, Fusarium sp. VP23 and Fusarium sp. VP36. The endophytic strains Alternaria sp. VP37, Fusarium sp. VP35 and strain VP18 stimulated superior seedling growth. The present research work reveals that some endophytic fungi of the Alternaria and Fusarium genera can behave as pathogens during the germination stage, while others have the function of promoting quinoa growth.
