Other claims from this paper (19)
- Observation All 14 Macrophomina phaseolina isolates infected Giza 21 soybean with varying charcoal rot severity.
- Observation Isolate S13 caused the highest charcoal rot severity, 60%.
- Observation Isolate S11 caused 57.9% charcoal rot severity.
- Observation Isolate S8 caused 56.3% charcoal rot severity.
- Intervention effect At 2.5 mM, riboflavin produced maximum resistance induction; higher concentrations did not improve it.
- Intervention effect Riboflavin treated and pathogen inoculated soybean grew higher and had greater fresh and dry weight than water treated inoculated plants.
- Intervention effect Thiamine treated and pathogen inoculated soybean grew higher and had greater fresh and dry weight than water treated inoculated plants.
- Intervention effect The highest fresh and dry weights occurred with 10 mM riboflavin.
- Intervention effect The highest fresh and dry weights occurred with 10 mM thiamin.
- Intervention effect Riboflavin induced resistance within one day, peaking at five to seven days before declining.
- Intervention effect Thiamine induced resistance within one day, peaking at six to eight days before declining.
- Intervention effect Seed soaking with either inducer significantly reduced damping off, root rot, and charcoal rot severity in both field seasons.
- Intervention effect The seed treatments significantly increased nodule number and fresh and dry nodule weight in both seasons.
- Observation Thiamine generally produced the best results under greenhouse and field conditions.
- Intervention effect Thiamine increased PO, PPO, PAL, and chitinase activity in inoculated and noninoculated soybean.
- Intervention effect Riboflavin increased PO, PPO, PAL, and chitinase activity in inoculated and noninoculated soybean.
- Observation Defense enzyme activity began accumulating after two days and peaked at six to eight days before declining.
- Intervention effect Thiamine and riboflavin increased total phenols and lignin in infected soybean.
- Observation Phenols peaked on day six and lignin on day ten after application.
