Small sized seeds, such as the horticultural species, have limited quantities of reserves that can be balanced by coating then with essential nutrients for their initial development. In addition, inoculation of the seeds with microorganisms may protect the plants against phytopathogens, thus enhancing their growth. The present work had the objective of evaluate the physiological quality and seedling development of sweet pepper seeds and seedlings coated with several kind of films. Seeds were first coated with polymers and then with antagonistic microorganisms (Trichoderma viride, Trichoderma polysporhum, Trichoderma stromaticum, Beauveria bassiana, Metarhizium anisopliae), mycorrhizas, aminoacids, micronutrients and plant growth regulators. Evaluation was performed for percentage of germination and for seedling emergence, speed of emergence index, number of plants, dry mass of the aerial and root parts and height of the seedlings. Inoculation with Trichoderma viride increased the percentage and rate of the seedlings emergence Inoculation with Trichoderma viride, Metarhizium anisopliae and mycorrhizas promote better seedling development; seed microbiolization with microorganisms Trichoderma viride, T. polysporhum, T. stromaticum, Beauveria bassiana, Metarhizium anisopliae. Mycorrhizas mixture negatively affected seeds and seedling quality. Seed covering with plant growht regulator, at a 5 mL kg-1 dose increased the roots dry matter. Em sementes pequenas, como as de espécies hortícolas, as limitadas quantidades de reservas podem ser equilibradas por meio do seu recobrimento com nutrientes essenciais para o seu desenvolvimento inicial. Além disso, a inoculação dessas sementes com microrganismos, além de proteger as plantas contra fitopatógenos, pode promover o seu crescimento. Assim, objetivo do presente trabalho foi avaliar o efeito de tipos de revestimentos na qualidade de sementes e mudas de pimentão (Capsicum annum). Para tanto, as sementes foram primeiro revestidas com polímeros e depois foram adicionados microrganismos antagônicos (Trichoderma viride, Trichoderma polysporhum, Trichoderma stromaticum, Beauveria bassiana, Metarhizium anisopliae), micorrizas, aminoácidos, micronutrientes e reguladores vegetais. Avaliaram-se a porcentagem de germinação e de emergência, o índice de velocidade de emergência, o número de plantas, a massa seca de parte aérea e de raiz e a altura da parte aérea das mudas. A inoculação de sementes com Trichoderma viride aumentou a porcentagem e o índice de velocidade de emergência das plântulas; Trichoderma viride, Metarhizium anisopliae e as micorrizas inoculadas às sementes dessa espécie promovem melhor desenvolvimento das mudas; a microbiolização de sementes com a mistura dos microrganismos Trichoderma viride, T. polysporhum, T. stromaticum, Beauveria bassiana, Metarhizium anisopliae e micorrizas afetou negativamente a qualidade das sementes e mudas de pimentão e o revestimento dessas sementes com regulador vegetal, na dose de 5 mL kg-1 de sementes proporciona aumento na massa seca das raízes das plantas
