MEDEIROS, José George Ferreira et al. Control of fungi and physiological quality of soybean seeds (Glycine max L.) subjected to moist heat. Rev. de Ciências Agrárias [online]. 2019, vol.42, n.2, pp.191-200. ISSN 0871-018X.  https://doi.org/10.19084/RCA.17182.

The quality of soybean seeds (Glycine max L.) is an important factor for the success of the crop, since the seeds can serve as source of inoculum for the dissemination of diseases. Thus, the objective of this work was to evaluate the effect of the thermotherapy via humid heat on the sanitary and physiological quality of the soybean seeds. The seeds used were from the cultivar FTS ATHENA RR, which were subjected to the following treatments: control (untreated seeds), fungicide (dicarboximide) and the heat treatments at 40, 50 and 60 ºC for five and ten minutes water immersion. The seeds were subjected to sanity and emergency tests in a completely randomized experimental design. Immersion of the seeds at 40, 50 and 60 ° C for five and ten minutes was not efficient to prevent the incidence of Penicillium spp., Aspergillus niger Link and A. flavus Tiegh. The temperatures of 40 and 50 ºC in all the immersion times reduced the fungal microflora of aerial part and soil without affecting the physiological quality.
