StomaAI (SAI) is a third-party app for auto-measuring stomatal density and pore features (width, length and area) from microscope images with human-level accuracy via deep computer vision. Further information can be found in our published paper (DOI:10.1111/nph.18765).
The leaf Stomatal density repository contains a collection of adaxial and abaxial stomatal densities for different species, compiled from published articles. The repository uses a search engine to find and count the species requested. The format of the repository includes the plant species' name, adaxial and abaxial stomatal density, the stomatal density ratio (Sr=adaxial/abaxial) and the link to the reference (paper DOI). This is the first repository released by plantphysiologist.com, and we are starting with a collection of 384 species. The repository is always growing and we welcome anyone sharing their published information about leaf stomatal density. To include your data, contact us and we can send you the template of the repository.
The wrong units were used in the equation to calculate ws. The error has been corrected in the version 1.1 Find the file in the Utilities tab.
This is a self-developed add-on for LI6800 by plantphysiologist.com. The add-on includes calculations of gas exchange parameters accounting for small fluxes as presented by Márquez, Stuart-Williams, and Farquhar (2021) (MSF). The incorporation of the add-on is via the configuration function included in the tab “Start up” of the LI6800. The add-on was developed for the LI6800’s software version 2.0.04 but was tested in the version 1.5.02 as well. The add-on does not replace the previous calculations performed by the LI6800 but adds a set of columns and rows to the data file including the new calculations and parameters.
It is handy to estimate total cuticular conductance accurately with the most common setup of gas exchange instruments. Find it in the menu Web-apps.
