SUMMARY

Barley grown at an upland site in the Pennines (Malham) produced grains that were smaller than those of plants grown at the same latitude, but 300 m lower altitude (Lancaster) and at a site in the region of commercial barley production (Cambridge). Grain development occurred 1 month later in the upland climatic conditions. The physiology of grain-development was investigated and a climatic effect on the capacity of the grains to accept assimilates is suggested as the cause of lower grain-weight at the upland site.
