Intervention effect Lenient cutting increased inflorescence number per plant.
Intervention effect Lenient cutting increased spikelets per inflorescence.
Association Plants producing the most florets had the most preflowering tillers and the greatest decline in tillering after harvest.
Observation The tillering pattern implied selection toward L. multiflorum genotypes in the seed population.
Observation Strongly awned plants produced fewer florets than weakly awned plants.
Observation Awn data implied a shift away from L. multiflorum.
