The Effects of Bipolaris Sorokiniana on Barley Seed Quality
In New Zealand, the germination of some field-dressed barley seed lots was reduced in 1986 because of seedling abnormalities caused by B. sorokiniana (Cochliobolus sativus). The effect was significant only when seedborne inoculum levels were >90%. Lab. tests for germination, abnormal seedlings an...

| Summary: | In New Zealand, the germination of some field-dressed barley seed lots was reduced in 1986 because of seedling abnormalities caused by B. sorokiniana (Cochliobolus sativus). The effect was significant only when seedborne inoculum levels were >90%. Lab. tests for germination, abnormal seedlings and seedborne inoculum did not correlate strongly with field emergence over 5 spring sowings. Results for seed lots with high levels of C. sativus 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 av. percentage of infected seedlings increased from 17 to 44%.

| Bibliography: | Australasian Plant Pathology publishes new and significant research in all fields of plant pathology. Distribution and readership of the journal is worldwide, but emphasis is placed on strengthening its role as the major publishing outlet in the Australasian region. Australasia is interpreted in the broadest sense to include not only Australia, New Zealand and Papua New Guinea, but also the Indian Ocean, Pacific and Asian regions |
