摘要: Significant increases in pre-emergence seedpiece decay and preemergence shoot infection were observed asErwinia carotovora var.atroseptica inoculum density increased. As increased, a point was reached where virtually 100 per cent of the disease expressed as no typical postemergence blackleg occurred.
