FITTING SEED GERMINATION CURVES IN GENSTAT

This experiment examined the effects of various factors on the rate of germination of chickweed seeds.

The experiment consisted of a three-replicate complete factorial arrangement with the factors :

Seed populations (3) ;
Collections within populations (3) ;
Sowing temperatures (2).

In total there were 3 x 3 x 3 x 2 = 54 experimental units for which the number of seeds germinating was recorded daily over a period of 24 days.

The data and the Genstat code , which fits growth curves for each experimental unit and forms a table of the medians for each of the five parameters of the Gompertz curve , is provided here.
