Ivy photosynthesis light response

Source: R/example-data.R

A dataset containing photosynthesis measurements on four ivy plants.

ivy.df

Format

A data.frame object with 36 rows and 6 variables.

Details

For each plant a light response curve of photosynthesis was measured using a custom-built system and software that allowed controlling the concentrations of water vapour and carbon dioxide at the surface of the leaves, i.e., inside the air boundary layer.
