摘要：

Wheat grain yield decreased as symptoms of common root rot became more severe in plants with the same number of tillers. This trend was not as obvious in barley. However, as the season progressed, symptoms of common root rot were most severe on barley plants with the fewest tillers. In addition, the severity of the disease increased more rapidly on plants with the fewest tillers in wheat and barley. The major effect of the disease on yield reduction is that plants with more disease produce fewer tillers. A smaller effect is that grain yield per plant decreases as disease increases in plants with the same number of tillers, which indicates that common root rot decreases the yield of individual tillers.
