1Daily UV-B treatments and elevated CO_(2)increases pigment concentrations and net photosynthesis of basil(Ocimum basilicum L.)显示文摘Anthropogenic emissions have greatly influenced UV-B radiation incidence and CO_(2)concentration globally.The interactive effects of projected incidence on crops by the end of the century need to be studied to understand the implications.The use of sunlit plant growth chambers in combination with UV-B radiation and CO_(2)treatments was used to identify the individual and interactive effects on basil'Genovese'plants.Treatments included 0 and 10 kJ m−2 d−1 UV-B supplementation at ambient(437 ppm)or elevated(725 ppm)CO_(2)concentrations.Effects of UV-B by CO_(2)interactions existed for net photosynthesis,light-adapted maximal quantum efficiency,all plant pigment concentrations,and malondialdehyde.UV-B increased leaf temperature by approximately 1°C while elevated CO_(2)concentrations amplified superoxide dismutase and ascorbate peroxidase activity in basil leaves.Despite deleterious impacts on plant health,UV-B radiation is essential for stimulating healthful compounds in basil.Understanding the effects when combined with elevated CO_(2)is necessary to improve crop production and future research.T.Casey Barickman Skyler R.Brazel Akanksha Sehgal Charles Hunt Walne K.Raja Reddy 2022Technology in Horticulture2022,2,1:0
