Other claims from this paper (12)
- Intervention effect UV-A irradiation significantly increased leaf surface area relative to the control variant (value 23.3 as written).
- Intervention effect UV-B irradiation significantly increased leaf surface area relative to the control variant by 20.7%.
- Intervention effect UV-B irradiation significantly increased total flavonoid content by 74%.
- Intervention effect Additional UV-B and UV-C irradiation decreased antioxidant capacity by an average of 30% compared with the control and UV-A.
- Intervention effect Additional UV irradiation did not decrease the rate of photosynthesis relative to the control variant.
- Intervention effect UV-B irradiation gave the highest steviol glycoside concentration during budding and flowering, by 13.2.
- Intervention effect UV-C irradiation gave the highest steviol glycoside concentration during budding and flowering, by 11.3%.
- Intervention effect UV-C irradiation caused an increase in relative chlorophyll content in stevia, reflecting light stress.
- Intervention effect UV-C irradiation decreased the CO2 absorption rate of stevia.
- Intervention effect UV-C irradiation inhibited stevia plant growth.
- Intervention effect UV-C irradiation caused scorches and leaf morphology changes in stevia.
- Recommendation The authors recommend UV-B irradiation as an optimal type of irradiation based on a set of indicators.
