Other claims from this paper (18)
- Intervention effect Fusarium graminearum was eliminated from wheat RS2 at 60°C after 15 days, 70°C after 5 days, or 80°C after 2 days.
- Intervention effect F. graminearum was eliminated from barley B2 at 60°C after 21 days, 70°C after 9 days, or 80°C after 5 days.
- Intervention effect Cochliobolus sativus frequency substantially increased in barley B2 at 50 or 70°C.
- Intervention effect C. sativus incidence significantly declined in barley B2 at 80°C.
- Intervention effect P. teres was observed significantly more often in barley B1 after heating at 50 or 70°C.
- Intervention effect P. tritici-repentis detection in durum wheat AD1 and AD2 was unaffected at 50°C.
- Intervention effect P. tritici-repentis detection significantly increased over time in wheat AD2 at 70°C.
- Intervention effect P. tritici-repentis incidence in wheat AD1 initially increased and then decreased at 70°C.
- Intervention effect C. sativus, P. teres and P. tritici-repentis remained viable after 14 days at 70°C.
- Intervention effect C. sativus was undetected after 10 days at 80°C.
- Intervention effect Wheat germination at 12, 14 and 16% moisture was unaffected after 7 days at 70°C.
- Intervention effect Barley germination at the same moisture contents declined slightly after heating.
- Intervention effect Most samples retained germination rates after heat regimens sufficient to eradicate F. graminearum.
- Intervention effect Viability significantly declined for durum wheat AD2 at 70°C.
- Intervention effect Viability significantly declined for barley B1 at 70°C.
- Intervention effect Barley B2 germination increased at 70°C.
- Intervention effect Barley B2 germination declined at 80°C.
- Recommendation The authors recommend thermotherapy to control movement of F. graminearum and other heat sensitive pathogens in breeding germplasm.
