The relationships between, and changes in moisture content, 1000‐seed weight, germination percentage and seed yield were determined from anthesis onwards in ten amenity grasses in 1975. These relationships were used to indicate the optimum date for combine harvesting and to give some indication of the consequences which follow if harvest was not carried out at this stage. In all species seed moisture content declined, and 1000‐seed weight and germination increased to a maximum value, during ripening.
