| Abstract: | The ripening process in a tetraploid ryegrass is described in terms of seed moisture content changes. The heavier seeds of tetraploids appear to be shed at an earlier stage in the ripening process than those of diploid ryegrass. The seed moisture level at which a tetraploid ryegrass seed crop is harvested is shown to be a critical factor determining the yield and quality of from the crop harvested seed. |
