  ... Two tropical species of North Australia, Acacia crassicarpa and Eucalyptus pellita, have similar leaf size and leaf structure but different leaf angles. A. crassicarpa with near vertical leaf angle directly reduced photon absorption and leaf temperature (T ₗ) and had relatively high photosynthetic activity (P ₘₐₓ) and low xanthophyll cycle activity. In contrast, E. pellita with a small leaf angle ...

  ... We determined the interactive effects of irradiance, elevated CO₂ concentration (EC), and temperature in carrot (Daucus carota var. sativus). Plants of the cv. Red Core Chantenay (RCC) were grown in a controlled environmental plant growth room and exposed to 3 levels of photosynthetically active radiation (PAR) (400, 800, 1 200 µmol m⁻² s⁻¹), 3 leaf chamber temperatures (15, 20, 30 °C), and 2 exte ...

  ... The effects of salinity (sea water at 0 ‰ versus 30 ‰) on gross rates of O₂ evolution (J O₂) and net rates of CO₂ uptake (P N) were measured in the halotolerant estuarine C₄ grasses Spartina patens, S. alterniflora, S. densiflora, and Distichlis spicata in controlled growth environments. Under high irradiance, salinity had no significant effect on the intercellular to ambient CO₂ concentration rat ...

  ... Photoinhibition under irradiance of 2 000 µmol m⁻² s⁻¹ (HI) was studied in detached control (C) and water deficit (WD) leaves of grapevine (Vitis vinifera L.) plants. The degree of photoinhibition was determined by means of the ratio of variable to maximum chlorophyll (Chl) fluorescence (Fᵥ/Fₘ) and electron transport measurements. The potential efficiency of photosystem (PS) 2, Fᵥ/Fₘ, marginally d ...

  ... To assess photosynthesis and yield components' response of field-grown wheat to increasing ozone (O₃) concentration (based on diurnal pattern of ambient O₃) in China, winter wheat (Triticum aestivum L.) cv. Jia 403 was planted in open top chambers and exposed to three different O₃ concentrations: O₃-free air (CF), ambient air (NF), and O₃-free air with additional O₃ (CF+O₃). Diurnal changes of gas ...

  ... Over-expression of chloroplastic glycerol-3-phosphate acyltransferase gene (LeGPAT) increased unsaturated fatty acid contents in phosphatidylglycerol (PG) of thylakoid membrane in tomato. The effect of this increase on the xanthophyll cycle and chloroplast antioxidant enzymes was examined by comparing wild type (WT) tomato with the transgenic (TG) lines at chilling temperature (4 °C) under low irr ...
