Other claims from this paper (11)
- Intervention effect Si application significantly decreased rice blast incidence and severity index in the rice-Magnaporthe grisea pathosystem, with a control efficiency of 60.59%.
- Intervention effect No significant difference in root dry weight was observed between Si-added and no-Si treatments of rice.
- Observation POD activity in rice leaves increased after inoculation and reached a maximum by 5 d.
- Intervention effect After inoculation, POD activity in leaves of Si+ rice plants was significantly lower than in Si- plants.
- Association The authors conclude that the change in POD activity was not directly related to rice blast resistance but might be directly related to the damage degree of leaves infected by M.grisea.
- Intervention effect PPO activity in leaves of Si+ rice plants was significantly higher than in Si- plants from 4 d after inoculation onward.
- Observation PPO activity in both Si+ and Si- rice plants increased slowly after inoculation and peaked by 5 d.
- Observation PAL activity in both Si+ and Si- rice plants increased rapidly after inoculation, peaked by 24 h, and then began to decline.
- Intervention effect PAL activity in Si+ rice plants was 1.44-fold higher than in Si- plants.
- Intervention effect Application of silicon was beneficial for rice growth and alleviated the damage resulting from infection by M.grisea.
- Mechanism It is hypothesized that silicon mediates activities of key defense enzymes to induce natural defense responses in rice and so enhances resistance to rice blast.
