Other claims from this paper (9)
- Intervention effect Elevated CO2 increased leaf blast lesions relative to ambient CO2.
- Intervention effect Elevated CO2 lowered leaf silicon content.
- Mechanism Lower leaf silicon may have contributed to greater leaf blast susceptibility.
- Intervention effect Panicle blast severity was unchanged by elevated CO2 with artificial inoculation.
- Intervention effect Panicle blast severity was slightly but significantly higher under elevated CO2 in a spontaneous epidemic.
- Intervention effect The percentage of plants diseased by sheath blight was higher under elevated than ambient CO2.
- Intervention effect Average lesion height was similar between CO2 treatments.
- Intervention effect Elevated CO2 increased tiller number.
- Mechanism The higher number of tillers may have increased fungal sclerotia adherence to leaf sheaths.
