THE SEED SOURCE OF CERTAIN GRASSES IN RELATION TO HIGH ALTITUDE REVEGETATION

1972 Proceedings of the New Zealand Grassland Association  
The effects of seed source and seed size on germination and field performance were studied in five grasses. Greater seed weights were associated with better germination in Yorkshire fog, cocksfoot and timothy but not significantly so for Chewings fescue and browntop. In cocksfoot, Chewings fescue and timothy, higher seed weights were found in samples collected at altitudes above those generally used for the commercial seed production of the species. Results from field sowings of a range of
