flowers {GLMsData}

The average number of meadowfoam flowers

Description

The average number of meadowfoam flowers in given light conditions

Usage

data(flowers)

Format

A data frame with 24 observations on the following 3 variables.

Flowers

the mean number of flowers per meadowfoam plant, averaged over ten seedlings; a numeric vector

Light

the light intensity in \mumol per square metre per second; a numeric vector

Timing

when the light treatment was applied; a factor with levels PFI (photoperiodic floral induction) or Before (24 days before PFI)

Details

The data are collected from an experiment to study how to maximize Mermaid meadowfoam production. (Meadowfoam is a small plant from which a vegetable oil can be extracted.)

These data are consistent with those in Seddigh and Joliff (1994). The data were estimated from their Figure 3, and then adjusted to produce, as closely as possible, the statistics given on those graphs.
