TABLE 2.

P-values for the effects of plant species (perennial ryegrass and tall fescue), temperature (cool and warm for weeks 0-3, and cool, warm, transfer from cool to warm and transfer from warm to cool for week 6) on Epichloë sp. FaTG-3 strain AR501 endophyte infection frequencies (%) and mycelial biomass (mg/g).

Source of variation	P-value
	Week 0	Week 3	Week 6
Viable endophyte infection frequency
Plant species	–	–	< 0.001
Temperature	–	0.002	0.385
Plant species × Temperature	–	–	0.950
Biomass of endophyte mycelia
Plant species	0.495	0.004	< 0.001
Temperature	–	0.005	< 0.001
Plant species × Temperature	–	0.973	0.001

P-values for endophyte infection frequency data were generated via Type II Wald Chi-square tests, whilst P-values for endophyte mycelia data were generated by Fisher’s protected LSD test (P < 0.05). Values in bold are statistically significant (P < 0.05), – no analysis possible.
