Leaf carbon and water status control stomatal and nonstomatal ...
网页2020年1月18日 · Leaf photosynthesis is subject to both stomatal limitations and nonstomatal limitations (NSLs) (Buckley & Diaz-Espejo, 2015). Stomatal limitations refer to restrictions in the supply of CO 2 by diffusion through the …
Anatomical constraints to nonstomatal diffusion conductance …
网页2019年1月9日 · To resolve how these distinctive features influence nonstomatal diffusional limitations to photosynthesis, a structural and ultrastructural analysis of the photosynthetic organs was performed for each species. Groups and species varied strongly in their macroscopic and structural and ultrastructural characteristics (Video S1; Tables S5, S6).
Non-stomatal limitation of photosynthesis by soil salinity
网页2020年3月11日 · Until now, most research has concentrated around stomatal limitation to photosynthesis, while non-stomatal limitations receiving much less attention. This work summarizes the current knowledge of impact of salinity on chloroplast metabolism and operation and finding viable solutions to minimize it.
Photosynthesis and growth reduction with warming are driven …
网页2016年3月17日 · Our findings highlight the key role of nonstomatal factors (biochemical and/or nutritional) in reducing net carbon assimilation rates and growth under warming, which has important implications for projections of plant carbon balance under the warmer and drier climatic scenario predicted for drylands worldwide.
Heterogeneous saline water irrigation improves stomatal and nonstomatal …
网页2024年2月15日 · Salt affects stomatal and nonstomatal factors that hinder photosynthesis and cause chloroplast damage and starch accumulation. It also decreased chlorophyll contents and chlorophyll fluorescence parameters, which led to oxidative stress at the subcellular level and accelerated the aging process in salinized leaves ( …
New insights into the covariation of stomatal ... - New Phytologist
网页2017年10月31日 · In this paper we explore the hypothesis that the cost of stomatal opening arises from nonstomatal reductions in photosynthesis induced by lower leaf water potential (ψ l). We examine two specific hypotheses (CAP and MES) in which stomatal opening leads (via decreased ψ l ) to reductions in carboxylation capacity and mesophyll conductance ...
Stomatal and non-stomatal limitations to photosynthesis in …
网页2012年1月1日 · Photosynthesis response to water stress differs in young and old seedlings. In young, mainly stomatal limitations lead to fast recovery after re-watering. In old non-stomatal limitations lead to slow and incomplete recovery. The worst performance of old seedlings is due to increased leaf area to root volume. Unavoidable plant ageing du...
Nonstomatal versus Stomatal Uptake of Atmospheric Mercury
网页2009年2月2日 · Data showed that Hg concentration and air source had a significant effect (p < 0.001) on leaf-atmosphere Hg flux, with more deposition to the leaf occurring in elevated-Hg air, and in scrubbed air compared to ambient air.
Stomatal and nonstomatal limitations of photosynthesis in 19 …
网页The results of this landscape-based study indicate that the interaction of stomatal and nonstomatal limitations of A vary in a manner consistent with species' drought tolerance and site conditions, and that nonstomatal constraints to A in field plants during a moderate, season-long drought were generally not as severe as reported in controlled ...
Stomatal and nonstomatal limitations of photosynthesis in …
网页Light saturated photosynthesis (A) in field saplings of shade tolerant, intermediate, and intolerant tree species was analyzed for stomatal and nonstomatal limitations to test differences between species and sun and shade phenotypes during drought.
