In Vitro Evaluation of the Inhibitory Activity of Different Selenium Chemical Forms on the Growth of a Fusarium proliferatum Strain Isolated from Rice Seedlings.

ABSTRACT: In this study, the in vitro effects of different Se concentrations (5, 10, 15, 20, and 100 mg kg^-1) from different Se forms (sodium selenite, sodium selenate, selenomethionine, and selenocystine) on the development of a Fusarium proliferatum strain isolated from rice were investigated. A concentration-dependent effect was detected. Se reduced fungal growth starting from 10 mg kg^-1 and increasing the concentration (15, 20, and 100 mg kg^-1) enhanced the inhibitory effect. Se bioactivity was also chemical form dependent. Selenocystine was found to be the most effective at the lowest concentration (5 mg kg^-1). Complete growth inhibition was observed at 20 mg kg^-1 of Se from selenite, selenomethionine, and selenocystine. Se speciatio
