Description

Data include a measure of plant drought tolerance (P50, more negative values indicate plant stems can tolerate lower water contents), and mean annual precipitation of the location where the sample was taken. Data are for 115 individual species (species name not included). Data are from original source were simplified for the purpose of this book.

Usage

Format

A data frame with 115 rows and 2 variables:

annualprecip

integer Annual rainfall (mm) where the plant was sampled.

P50

double The negative water pressure in the xylem at which 50% of stem conductivity is lost. More negative indicates higher tolerance to drought.
