Structural dynamic of the annual ryegrass from defoliation to seeds harvest

The aerial part distribution and arrangement can significantly affect the forage resource’s use, both for leaves seeds harvesting. This work aimed to verify structure derived from different times of pasture use subsequent production in a long-cycle ryegrass cultivar. Weekly assessments number length living leaves, elongation internodes, tillering, plants’ height, structural components (leaf, stem, flower, dead material), yields components, yield, determine along its cycle. cv BRS Ponteio had modified just after 150 days (thermal sum: 1303 degrees-days) seeding without defoliation. Defoliation during vegetative period did not alter until seeds’ production. beginning internodes’ caused significant tillering growth, which maintained high potential, plants lodging, besides promoting more Subsequent determined predominant stems flower harvesting, compared reduction potential
