An overview of models of stomatal conductance at the leaf level
网页Stomata consist in pores scattered over the relatively waterproof and CO 2-tight cuticle covering the leaf surface. They play an essential role in controlling both water losses by transpiration and CO 2 uptake for photosynthesis and plant growth. Stomatal aperture is controlled by the turgor pressure difference between the guard cells ...
Modeling Stomatal Conductance | Plant Physiology - Oxford …
网页2017年1月6日 — By controlling the exchange of water and carbon dioxide between plants and the atmosphere, stomata play a central role in the regulation of leaf and plant water status and transport, photosynthesis, drought sensitivity and tolerance, competition for soil resources, and even landscape and global hydrology (Hetherington and …
A theoretical and empirical assessment of stomatal optimization ...
网页2020年4月5日 — Optimal stomatal control models have shown great potential in predicting stomatal behavior and improving carbon cycle modeling. Basic stomatal optimality theory posits that stomatal regulation maximizes the carbon …
An integrated model of stomatal development and leaf physiology
网页2013年11月19日 — Stomata are formed by two symmetric epidermal guard cells that regulate this flow by changing the size of the pore in response to both external environmental and internal plant cues (Kim et al., 2010).
Rotating Stomata Measurement Based on Anchor-Free Object …
网页This paper proposes a DeepRSD DL model that incorporates the features of rotating stomata to accurately determine key traits such as length and width, based on the stomata detection box size. Subsequently, the maximum stomata conductance algorithm is employed to calculate the maximum stomata conductance.

网页2021年12月1日 — Through this method, we: (1) automatically differentiate between distinctive stomatal types, the dumbbell shaped Poacaea and dicotyledonous stomata, (2) count stomata, (3) extract multiple morphological traits, (4) calculate density, and (5) calculate anatomical g smax as circular or ellipse based on the type of stomata.
Optimal stomatal behaviour around the world - Nature
网页2015年3月2日 — Analysis of a global database covering a wide range of plant functional types and biomes now provides a framework for predicting the behaviour of stomatal conductance that can be applied to model...
Modeling Stomatal Conductance - PMC - National Center for …
网页2017年1月6日 — Recent advances have improved our ability to model stomatal conductance using process- or optimality-based models, and continuing research should focus on how stomata sense leaf turgor and on how to quantify the …
Stomatal Conductance, Photosynthesis, and Transpiration, …
网页2014年1月1日 — In order to utilize water resources effectively, and to quantitatively evaluate plant production and interaction between the vegetation and the environment, we need to model mass and energy-exchange processes within the soil–plant–atmosphere system through stomatal conductance, photosynthesis, and transpiration.

网页2021年9月29日 — Stomata are highly dynamic valves in the epidermis of plants. These microscopic structures regulate the exchange of gases with the atmosphere and are essential for plant survival on land (Raven, 2002). There is an enduring fascination with stomata because of their specialized nature: from their unique development out of undifferentiated ...
