Stenocarpella maydis (Berk.) Sutton colonization of maize ears
Journal of Phytopathology - Phytopathologische Zeitschrift 143 (10), 597-599
Abstract: A study was undertaken to determine the ramification of maize shank, cob and kernel tissues by Stenocarpella maydis. Trials consisting of inoculated and uninoculated treatments were planted at two localities. Shank, cob and kernels of each treatment were divided into segments and S. maydis colonization was determined. Infection of the pedicel portion of maize kernels was significantly higher than the apical portion. Preferential colonization of the embryo's of kernels was observed. Colonization of cobs occurred primarily at the attachment end of the cob, with sclerenchymatous tissues showing the greatest re-isolation frequency. Shank segments did not show significant differences in S. maydis re-isolation frequency, although a tendency for higher re-isolations was observed at the stalk-attachment end. It is concluded that S. maydis colonization occurs at the base of the ear with mycelial ramification toward the tip of the ear. The sclerenchyma and placentae were the primary colonized cob tissues, as were the embryos in the kernels.
