Colonization type of gibberella zeae in sorghum bicolor

Abstract


The susceptibility of grain sorghum (Sorghum bicolor) to colonization by Gibberella zeae was assessed by isolation studies involving plants grown in the glasshouse. Studies on infection of sorghum seedlings by G. zeae indicated that this pathogen can infect the host at early growth stages and gradually colonize adjacent tissues as an endophyte. The results also showed that roots as well as stem tissues are susceptible to infection. Indeed, the result suggested that the fungus could infect and colonize the proximal parts of roots more aggressively than the leaf sheaths and stem tissues.
