t0“Enhancement of resistance against Rhizoctonia solani by glycine betaine and UV-C radiation in green bean (Phaseolus vulgaris L.)”
e1“Similarly, PPO exhibited higher activities with significant differences in all treatments over the infected control with percentages of 54, 59.4 and 48.7% for UV, GB and UV+GB respectively”
e2“guaiacol peroxidase (G-POD) and polyphenol oxidase (PPO) activities were elevated by all treatments in infected plant roots in comparison with control”

- Intervention effect Glycine betaine reduced the Rhizoctonia solani disease index in green bean by 54.7%.
- Intervention effect UV-C with glycine betaine reduced the disease index by 38.3%.
- Intervention effect UV-C reduced the disease index by 35.6%.
- Intervention effect UV-C reduced lipid peroxidation in infected plants relative to infected control, by 26.8%.
- Intervention effect Glycine betaine reduced lipid peroxidation in infected plants relative to infected control, by 40.2%.
- Intervention effect UV-C with glycine betaine together reduced lipid peroxidation in infected plants relative to infected control, by 29.3%.
- Association Lipid peroxidation level was highly correlated with the Rhizoctonia root rot disease index.
- Intervention effect UV-C seed treatment enhanced rooting of infected green bean seedlings compared with control.
- Intervention effect Glycine betaine seed treatment enhanced rooting of infected green bean seedlings compared with control.
- Intervention effect Alone or together, UV-C and glycine betaine enhanced rooting of infected green bean seedlings compared with control.
- Intervention effect Glycine betaine was the only treatment that significantly increased superoxide dismutase activity in green bean roots compared with control.
- Intervention effect UV-C gave the maximum G-POD activity in infected green bean roots, 9042.5 U.mg-1 protein, above infected control.
- Intervention effect GB+UV gave higher G-POD activity than infected control, 7776.5 U.mg-1 protein.
- Intervention effect GB gave higher G-POD activity than infected control, 7152.4 U.mg-1 protein.
- Intervention effect GB raised polyphenol oxidase activity in infected green bean roots by 59.4% over infected control.
- Intervention effect UV-C with GB raised polyphenol oxidase activity in infected green bean roots by 48.7% over infected control.
- Observation Combined UV-C and GB treatments showed no synergistic effect on induced plant tolerance.
- Mechanism UV-C and GB seed treatment is suggested to enhance seedling tolerance to R. solani through activation of antioxidant enzymes.
