Inhibition of photosynthesis

Description

Experiment investigating the inhibition of photosynthesis in response to two synthetic photosystem II inhibitors, the herbicides diuron and bentazone. The effect of oxygen consumption of thylakoid membranes (chloroplasts) from spinach was measured after incubation with the synthetic inhibitors, resulting in 5 dose-response curves.

Usage

data(spinach)

Format

A data frame with 105 observations on the following 3 variables:

CURVE
a numeric vector.
HERBICIDE
a character vector.
DOSE
a numeric vector.
SLOPE
a numeric vector.

Details

CURVE denotes a total of five independent assays with two herbicides. HERBICIDE denotes the names of the herbicides. DOSE is the concentration of the herbicides muMol and SLOPE is the oxygen consumption of thylakoid membranes.
