Germination rates of Abutilon angulatum at different temperatures

Description

Germination rates of Abutilon angulatum from 29 different studies, undertaken at different ambient temperatures. We would like to know how germination rate varies with temperature, in particular, the range of temperatures at which Abutilon angulatum will germinate. These data come from a larger study across species and environments to look for a latitudinal signal in tolerance to changing temperature (Sentinella et al 2020).

Usage

data(seedsTemp)

Format

A dataframe containing:

NumSown

The number of seeds sown.

NumGerm

The number of seeds that germinated.

Test.Temp

The ambient temperature (in degrees Celsius) of the location at which seeds were sown.

Examples

data(seedsTemp)
seedsTemp$propGerm = seedsTemp$NumGerm / seedsTemp$NumSown
plot(propGerm/(1-propGerm)~Test.Temp,data=seedsTemp,log="y",
