The effects of Bipolaris sorokiniana on barley seed quality

Abstract

The germination of some field-dressed barley seed lots was reduced in 1986 because of seedling abnormalities caused by Bipolaris sorokiniana. The effect was significant only when seedborne inoculum levels were greater than 90%. Laboratory tests for germination, abnormal seedlings and seedborne inoculum did not correlate strongly with field emergence over five spring sowings. Results for seed lots with high levels of B. sorokiniana underestimated field performance, because the field environment did not allow rapid disease development. However, the percentage of infected seedlings was linked to seedborne inoculum levels. With delayed sowing, the mean percentage infected seedlings increased from 17% to 44%.
