Abstract/Contents: | "Growth of the fungal endophyte (Sphacelia typhina) into tall fescue seedlings from infected seed aged 6 mo and older was studied at 15, 22, and 30 C. At all temperatures percent infection increased in seedling populations during a 2- to 3-wk period beginning within 2 wk of planting. Maximum infection and infection rate depended on seedlot, but within seedlots were always lower at 30 C than at 15 or 22 C. The fungus did not grow into the coleoptile or leaf blade, and infection of the seedling did not occur until the sheath of the first leaf was apparent. The endophyte was frequently observed in sheaths less than 1 mm long. Establishment of infection in seedling populations coincided with the period of early development of the first leaf sheaths. Decreased infection rates at 30 C were not related to sheath differentiation since the rate of differentiation was similar at 22 and 20 C. Infection of subsequent leaves also coincided with sheath differentiation." |
