Endophytic occurrence of Beauveria bassiana GHA inA) roots, B) stems, and C) leaves.
Data are presented for two time points, 14 and 21 days after planting, and for three concentrations of B. bassiana conidia that were used to inoculate maize seeds: control = 0 conidia/ seed, low = 3 × 108 conidia/ seed, and high = 3 × 109 conidia/ seed. Bar heights are the proportion of samples displaying endophytism, error bars are the standard error of the proportion. An asterisk indicates a significant difference from the control.

Endophytic occurrence of Beauveria bassiana MA20 in A) roots, B) stems, and C) leaves.
Data are presented for two time points, 14 and 21 days after planting, and for three concentrations of B. bassiana conidia that were used to inoculate maize seeds: control = 0 conidia/seed, low = 3 × 108 conidia/seed and high = 3 × 109 conidia/ seed. Bar heights are the proportion of samples displaying endophytism, error bars are the standard error of the proportion. An asterisk indicates a significant difference from the control.

Endophytic occurrence in maize for two strains of Beauveria bassiana:
A) GHA and B) MA20. Data are presented for two time point, 14 and 21 days after planting, and for three concentrations of B. bassiana conidia that were used to inoculate maize seeds: control = 0 conidia/seed, low = 3 × 108 conidia/seed and high = 3 × 109 conidia/ seed. Bar heights are the proportion of samples displaying endophytism, error bars are the standard error of the proportion. An asterisk indicates a significant difference from the control.

Colony forming units (CFU) per ml of vermiculite for two strains of Beauveria bassiana:
A) GHA and B) MA20. Data are presented for two time point, 14 and 21 days after planting, and for three concentrations of B. bassiana conidia that were used to inoculate maize seeds: control = 0 conidia/seed, low = 3 × 108 conidia/seed and high = 3 × 109 conidia/ seed. Bar heights sample means, error bars are the standard error of the means. An asterisk indicates a significant difference from the control.
