Abstract

Annual ryegrass, perennial ryegrass and tall fescue grasses are agronomically important grasses for pastures, amenity and erosion control. Cool season grasses such as these are often infected with a systemic fungal endophyte that has been shown to provide increased tolerance to both biotic and abiotic stresses. Temperatures for seed storage have been manipulated to decrease dormancy and, in some cases, to remove viable endophyte. A study of the effect of temperature on seed germination and plant biomass production was undertaken. Annual ryegrass, perennial ryegrass and tall fescue seed were stored under regimes of 4o, 25o and 60oC over periods of 4, 8 and 12 days. Temperature significantly affected seed germination whereas grass line influenced both seed germination, tiller number and plant biomass production.
