e0“We quantified the changes in growth, morphology, photosynthesis, and phenolic contents of sweet basil grown under a base red/blue/green LED light with four supplemental UV-A intensity treatments (0, 10, 20, and 30 W·m −2 ) in an indoor environment over 14 days”
e6“Mild UV-A radiation (10–20 W·m −2 ) can be a beneficial stressor to improve sweet basil yield and quality over relatively long-term cultivation”

Other claims from this paper (7)
- Intervention effect Sweet basil biomass at 14 days after treatment was highest under 10 W·m −2 UV-A.
- Intervention effect Sweet basil biomass at 14 days after treatment was lowest under 30 W·m −2 UV-A.
- Intervention effect The 30 W·m −2 UV-A treatment significantly lowered total leaf area and leaf number of sweet basil compared with the 10 and 20 W·m −2 treatments at 14 DAT.
- Intervention effect The maximum quantum efficiency of PSII (Fv/Fm) of sweet basil decreased gradually from 3 to 14 DAT under the 20 and 30 W·m −2 UV-A treatments.
- Intervention effect The maximum quantum efficiency of PSII (Fv/Fm) of sweet basil remained relatively constant under 0 and 10 W·m −2 UV-A over 14 days.
- Intervention effect The leaf net photosynthesis rate of sweet basil decreased by 17.4% under the 30 W·m −2 UV-A treatment compared with 10 W·m −2 at 14 DAT.
- Intervention effect Phenolic contents (PAL enzyme activity, total phenolic concentration and antioxidant capacity) of sweet basil were highest under 20 W·m −2 UV-A, followed by 10, 30 and 0 W·m −2.
