摘 要:The present work aimed to study the treatment with the bioprotector Trichoderma harzianum on maize seeds immediately after treatment and during *** seeds were analyzed through germination test,vigor tests(cold test,accelerated aging and aerial length),and the viability of the treated seeds was verified through the *** treatment is recommended because approximately 90%of crops intended for human and animal feeding are seed-propagated.A pathogen present in the seed results in increased diseases in the adult plant,in addition to introducing pathogens in other *** the seed treatment can provide better results than chemicals disease control on *** have antagonistic fungi that produce metabolites and enzymes that will avoid the proliferation of phytopathogenic *** the bioprotectors,Trichoderma spp.,used for phytosanitary control of seeds,stands *** tests were carried out with treatment in order to evaluate the physiological potential caused by the treatment with the *** biospeckle experimental runs were performed in parallel with the sanitation *** germination percentages of 93.0%,87.5%,and 87.5%,respectively,showed that they were all above the minimum requirement for commercialization,which is 85%.Analyzing the vigor and sanitation tests,it was verified that the best treatment was on day *** the seeds analyzed through biospeckle,using the laser speckle contrast analysis(LASCA)technique,it was possible to identify fungi activity.
