Other claims from this paper (6)
- Association The number of lesions per rice leaf decreased with the amount of Si applied.
- Mechanism Si in the rice leaf epidermis may confer resistance against appressorial penetration by the rice blast fungus.
- Mechanism Si also confers physiological resistance against blast infection after penetration.
- Association Relative Si levels on the adaxial leaf surface increased with the amount of silica gel applied to rice plants.
- Observation Si amounts in the youngest rice leaves were consistent with the amounts of silica gel applied.
- Association The proportion of appressorial penetration increased with the length of the period after spray inoculation.
