RESUMO A mancha de Bipolaris, causada por Bipolaris maydis, é uma das principais doenças foliares de Zea mays,apresentando um considerável potencial de dano, notadamente, na cultura do milho-pipoca, embora trabalhos sobreeste patossistema ainda sejam escassos. Neste trabalho, avaliaram-se as influências de diferentes meios de culturasobre o crescimento micelial, esporulação e a infectividade de inóculo conidial de B. maydis em folhas da cultivarsuscetível Beija-flor, de milho-pipoca. Para tal, instalaram-se experimentos em laboratório e em casa de vegetação emblocos casualizados com quatro repetições. Em laboratório, avaliaram-se o crescimento micelial e a esporulação de B.maydis em diferentes meios de culturas (Batata Dextrose Ágar, Feijão Ágar, Água de Coco Ágar, Arroz Polido Ágar,Folha de Milho Ágar e Lactose Caseína Ágar). Em casa de vegetação, avaliaram-se o número de lesões por folha e aincidência de doença na planta suscetível inoculada com uma suspensão de 104 conídios/mL. O meio de Arroz PolidoÁgar foi o que mais promoveu o crescimento micelial do fungo, porém não favoreceu a esporulação. Para esporulação,destacaram-se os meios de cultura Batata Dextrose Ágar e Feijão Ágar. Maior número de folhas com sintoma dadoença e maior número de lesões por folha foram obtidos com o inóculo produzido no meio Feijão Ágar.Palavras-Chave: Zea mays L., Crescimento micelial, Mancha de Bipolaris, Esporulação, Milho-pipoca.CULTURAL AND PATHOLOGICAL FEATURES OF Bipolaris maydis IN DIFFERENT CULTURE MEDIAABSTRACT. The Southern corn leaf blight, caused by Bipolaris maydis, is a major foliar disease of corn, presentingconsiderable potential of damage, especially in Zea mays, although studies with this pathosystem are still scarce. In thispaper, the effect of different culture media was evaluated on mycelial sporulation and infectivity of conidial inoculum ofB. maydis on leaves of the susceptible cultivar Beija-Flor, of corn-popcorn. Experiments in laboratory and greenhousewere installed in a randomized blocks design with four replications. The mycelial growth and sporulation of B. maydison different culture media (Potato Dextrose Agar, Bean Agar, Coconut Water Agar, Rice Polished Agar, Corn LeafAgar Lactose Casein Agar) were evaluated in the laboratory. In the greenhouse it was evaluated the number of lesionsper leaf and the incidence of disease in susceptible plants inoculated with a suspension of 104 conidia/ml. The culturemedium Polished Rice Agar promoted the highest mycelial growth, but did not promote sporulation. Sporulation washigher on culture media Potato dextrose Agar and Agar Bean. A greater number of leaves with symptoms of the diseaseand a higher number of lesions per leaf were obtained with the inoculum produced in the culture medium Bean Agar.Keywords: Zea mays L, Mycelial growth, Southern corn leaf bligh, Sporulation, Popcorn.

This study aims to determine the effect of MS0 medium density on maize in vitro seed germination. The sample used in this study is corn kernels from local variety (Zea mays L. var. “Lokal”). This research was an experimental research with a quantitative method approach. The study used a Rancangan Acak Lengkap (RAL) with one treatment factor that is medium density MS0 with a degree of agar concentration are 4 gram, 6 gram, 8 gram and 10 gram each concentration repeated 3 times. Data analysis uses the One Way Analysis of Variant (ANOVA) test and if it shows significant results, test continued to BNJ test (Beda Nyata Jujur). The best growth results occur at low level medium density (agar 4 gram) based on parameters days of emerged buds, plant height, number of roots, number of leaves and wet weight of corn plantlets. Uji ANOVA showed that F value calculated 41.333 bigger than F value table that is 4.07 with significance level 0,05. This result shows that H0 is rejected and Ha is accepted. The results are continued with the BNJ test. BNJ test obtained significantly different results on germination of corn kernels in all treatments. The wet weight of corn plantlets has a high influence on the organs (roots, stems and leaves) of plants. If the wet weight is high, the plant growth is significant and vice versa.
