The performance of high‐latitude grass varieties under Scottish conditions: seasonal distribution of dry‐matter production
Abstract The seasonal patterns of dry‐matter (DM) production by swards of Norwegian grasses originating from high latitudes >61°N ( Dactylis glomerata Hattfjelldal, Phleum pratense Engmo and Poa pratensis Leikra) were compared over 2 years (1986 and 1987) with those of grasses developed at lower...

These findings are compatible with the observed stimulation of DM production of high‐latitude grasses by daylength extension under controlled conditions. However, since the stimulation of DM production did not occur until the normal peak of production in May and June, it served to accentuate the skewed distribution of production in Scotland, rather than to improve production earlier in the season.
