Physiological and sanitary quality of ryegrass seeds submitted to different defoliation frequencies

Abstract: This study determined the effect of different defoliation frequencies in a long-cycle ryegrass cultivar on yield components and the physiological and sanitary quality of seeds. Four defoliation frequencies were applied (without, one, two, and three defoliations). The time between defoliations was 350 degree-days. At the first, second, and third defoliation time, the plants were 15 cm, 20 cm, and 35 cm, respectively, and were lowered to half their height. The yield components and plant structure were evaluated … Show more

“…The aerial tillering was not affected by the number of defoliations, which remained between 30 and 50% of the plant's tillers (Cunha et al, 2022). This structural feature has rarely been discussed earlier in literature for this plant.…”
