by comparing temperature sensitivity of growth, basic physiological processes such as photosynthesis, and survival across a range of temperatures ( Burke, 1990 , 1995 ; Hopkins, 1999 ; Lambers et al., 1998 ; Larcher, 1994 ; Leegood, 1995 ). The
bermudagrass cultivar Chuanxi exhibits higher shade tolerance, a higher net photosynthetic rate, and total chlorophyll than three triploid hybrid bermudagrass cultivars Tifdwarf, Tifsport, and Tifway under shade stress ( Cao et al. 2022 ). Photosynthesis is
overall reduction in growth but no obvious signs of visible damage ( Wellburn, 1990 ) and mainly affect the physiological metabolism of plants. Chlorophyll (Chl) is the most important plant pigment because it has a crucial role in photosynthesis ( Croft et
lettuce ( Luo et al. 2012 ; Sun et al. 2016 ), bent grass ( Xu and Huang 2000 ), and rice ( Kuwagata et al. 2012 ). Photosynthesis is one of the most important physiological processes that determine plant growth, and it is sensitive to temperature
injury to plants would be expected to result in an increase in respiration and possibly a reduction in photosynthesis. A concomitant decrease in photosynthesis and increase in respiration could cause a harmful depletion of carbohydrates. Few studies have

Models indicate that ozone inhibits carbon assimilation largely in the upper canopy, due to light and ozone gradients. We document yield reductions and ozone gradients in Casselman plum in open-top ozone fumigation chambers. Ambient air (12 hr mean ozone = 0.050 ppm), charcoal filtered air (0.034 ppm) and ambient air plus added ozone (0.094 ppm) were circulated in the chambers. Additional trees grew outside the chambers (0.058 ppm). Outside the chambers large vertical and horizontal gradients in ozone within the canopy were documented, but these were absent in the chambers. Ozone decreased leaf photosynthesis by 31% and 58%, and fruit yield by 20% and 66%, in the ambient and ozone enriched relative to filtered chambers. Despite altered gradients, yield and photosynthesis of exposed leaves were similar inside and outside the chambers in ambient air. Compensatory changes in leaf function may be involved.
