P-values for the effects of Temperature (high and low), Species (perennial and Italian), Plant part (pseudostems and leaves) and their interactions from the analysis of epoxy-janthitrem concentration in ryegrass at the beginning of the trial, after 4 weeks and after 10 weeks of growth in the controlled environment rooms.

	P-value

Plant part	<0.001	<0.001	<0.001
Temperature	0.181	<0.001	<0.001
Species × Plant part	0.005	0.523	0.429
Temperature × Plant part	0.205	<0.001	<0.001
Species × Temperature	0.315	0.884	0.701
Species × Temperature × Plant part	0.849	0.877	0.089

Bold values are the statistically significant (P < 0.05) values.
