Other claims from this paper (15)
- Intervention effect Silicon supply reduced chlorotic leaf area of wheat by 50.2% relative to no silicon
- Intervention effect Silicon supply made no difference to incubation period, latent period or necrotic leaf area
- Intervention effect Silicon supply made no difference to leaf streak severity estimated by software
- Intervention effect Silicon supply made no difference to calcium content of wheat leaf tissue
- Intervention effect Silicon supply made no difference to the bacterial population on leaf tissue
- Intervention effect Bacterial population on leaf tissue seemed somewhat lower with silicon supply at 4 to 8 days after inoculation
- Intervention effect Silicon supply made no difference to electrolyte leakage from wheat leaves
- Observation Total soluble phenolics and LTGA derivatives did not increase during wheat infection
- Association Phenolics and LTGA derivatives seemed slightly higher in wheat not supplied with silicon at the most advanced infection stages
- Association Chitinase activity was high in silicon-supplied wheat leaves at the most advanced infection stages
- Mechanism Chitinase activity probably reduced growth of Xanthomonas translucens pv. undulosa on wheat leaves
- Intervention effect Peroxidase activity was not increased by silicon during wheat infection
- Association Peroxidase activity may be linked with the highest LTGA derivative concentration at 12 days after inoculation in silicon-supplied plants
- Association Polyphenoloxidase activity did not affect wheat resistance to leaf streak under either silicon treatment
- Association Supplying silicon to wheat can increase resistance to leaf streak, possibly through tissue lignification and chitinases and peroxidases
