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
