Carbon dioxide fertilization effect on plant growth under soil water stress associates with changes in stomatal traits, leaf photosynthesis, and foliar nitrogen of bell pepper (Capsicum annuum L.)

Irrigation decision model for tomato seedlings based on optimal photosynthetic rate

“…The analysis of Pearson correlation between photosynthetic rate and environments showed that PPFD, CO 2 concentration, and soil moisture all had a great influence on the photosynthetic rate (Table 1). This is likely because that light is an energy source of photosynthesis [31] , and both CO 2 and water are reactants of photosynthesis [32] . Additionally, temperature is an important factor influencing the photosynthesis of plants as well, but the temperature set in this thesis is suitable for tomato growth [33,34] , resulting in the correlation between temperature and photosynthetic rate being non-significant.…”

Impacts of climate changes on risk zoning for cowpea in the Amazonian tropical conditions

“…Higher atmospheric [CO 2 ] primarily affects the net photosynthesis of C 3 plants by increasing net photosynthesis and carbon assimilation, which is counteracted by a reduction of stomatal opening, that reduces the transpiration of the plant (Ueyama et al, 2020). One could expect this reduction in plant transpiration to increase the crop resistance to drought, however a research about the effect of CO 2 fertilization and water deficit on cucumber, another C 3 plant, has shown that severe water stress would reduce or even offset the possible benefits brought by increased atmospheric [CO 2 ], which, according to the authors, suggests that ecological models based on strong CO 2 fertilization may overestimate the benefits of plants from rising atmospheric [CO 2 ] (Fan et al 2020). As there is not any recent experiment regarding the effects of increased atmospheric [CO 2 ] on cowpea, the current research does not account for effects of CO 2 fertilization on cowpea.…”

Anatomical Changes of Cultivated Plants under Combined Stress: An Urgent Need for Investigation

“…Under stress, different changes might be impaired in morphological, physiological and biochemical traits and processes in stressful plants. These processes may include all biological processes in stressful plants such as leaf photosynthesis (Fan et al 2020), metabolism of pollens (Nischal and Sharma 2020), and nearly all processes. The biochemical traits may include the antioxidant defense system and enzymes, whereas the physiological parameters may include all physiological processes like photosynthesis and the morphological features involve all features linked to the shape of plant organs like leaves, stems, and roots (Seleiman et al 2021).…”
