Abstract

Five flax (Linum usitatissimum L.) cultivars, Dufferin, McGregor, Linott, NorLin and NorMan were grown in the field in 1985, 1986 and 1987 at seeding rates of 200, 400, 600 and 800 seeds m −2 . Averaged over all cultivars and years, as seeding rate increased from 200 to 800 seeds m −2 , maturity was hastened 2.1 d, seed weight decreased 0.16 g 1000 −1 seeds, oil content decreased 0.6%, iodine number decreased 1.3 units and volume weight was not markedly changed. Lodging increased and basal branching decreased from 1.68 to 0.18 branches per plant as seeding rate increased. Plant height increased 0.6 cm from the 200 to the 400 seeds m −2 rate then decreased 1.8 cm from the 400 to the 800 seeds m −2 rate. Seed yield increased from 110 to 124 g m −2 as seeding rate increased from 200 to 600 seeds m −2 , then decreased to 121 g m −2 at 800 seeds m −2 . Although yields of the five cultivars varied somewhat in their response to seeding rate and year, most yielded near optimum at the 600 seeds m −2 seeding rate.Key words: Flax, Linum usitatissimum L., seeding rate, lodging
