The mollicutes corn stunt spiroplasma (CSS; Spiroplasma kunkelii) and maize bushy stunt phytoplasma (MBSP) infect maize phloem tissue and disturb its physiology and kernel production. These pathogens are disseminated by the leafhopper Dalbulus maidis, and cause severe corn stunting accompanied by drastic decrease in kernel production. The effects of these diseases on kernel production, nutrition and water retention of different tissues of several maize cultivars were evaluated. The experiment was carried out in a factorial design consisting of 3 inoculation treatments (healthy plants, phytoplasma-infected plants, and spiroplasma-infected plants) and 6 cultivars of maize (Zea mays L). Plants infected with mollicutes sustained reduced plant height and kernel production, however the magnitude of these effects varied among cultivars and was generally greater for spiroplasma-infected plants than for phytoplasma-infected plants. Mollicute infections reduced the overall in plant concentration of Mg and amounts of nutrients (K, Mg, P, N, Ca and Zn) taken up by plants tissues. These effects were variable for different maize cultivars. However, mollicute infection did not affect the nutrient concentrations in the kernels. At 100 days after planting, ratios of water to dry matter were similar among healthy plants, but were highly variable among CSS and MBSP-infected cultivars, the latter two groups retaining on average 15% to 40% more water than healthy cultivars. The water potential values of diseased plants were variable but were not clearly distinct among healthy and diseased plants.
