FIG. 4.
Effects of inoculum levels and light conditions on inoculation of maize plants by F. verticillioides. (a and b) Effect of two levels of inoculum on the amount of mycelium that developed in the mesocotyl 30 days after seeds were planted in inoculated soil. The inocula used were 0.1 g (fresh weight) per kg of soil (a) and 0.6 g (fresh weight) per kg of soil (b). (c and d) Development of mycelium in roots (c) and mesocotyls (d) of plants grown under low-light conditions (20 microeinsteins m−2) 14 days after inoculated seeds were planted in disinfested soil.
