Abstract:
The establishment of economic enterprises and the demand for coastal areas for leisure purposes exert
great pressure on the dunes, stripping them of vegetation and causing the aggravation of coastal
erosion processes. The use of arbuscular mycorrhizal fungi (AMF) is a viable alternative to restore
dunes, giving their ability to improve soil conditions and plant growth under unfavorable conditions.
The aim of this study was to evaluate the effect of AMF on the growth of Canavalia rosea (Sw.) DC. For
the experiment, two treatment groups were set up (16 pots with arbuscular mycorrhizal fungi inoculum
and 16 pots without) over a period of 10 weeks. It was found that C. rosea (Sw.) DC. responded
positively to the inoculation with the AMF and the percentages of colonization were 6.4 and 10.2% in the
eighth and tenth week of plant growth, respectively. Also, the growth of Canavalia rosea (Sw.) DC.
increased significantly with AMF throughout the experiment. This proved the efficacy of arbuscular
mycorrhizal fungi as promoters of dune plants ́ growth, and as potential strategy for the rehabilitation
of dunes in the coastal areas
