Losses are higher in hybrid seed production fields due to a higher susceptibility of male sterile lines. The sclerotia of C. sorghi have never been found to contain alkaloids with a tetracyclic ergoline ring system, which is normal in most ergot pathogens. In this work, we show that sclerotia of C. sorghi contain caffeine alkaloid and the ability to produce it in vitro.pdfenOpen Accessin vitro growthsclerotiaalkaloidSorghum bicolorCafeicultura::Pragas, doenças e plantas daninhasArtigo
