Tamaño de semilla en la calidad fisiológica de Dactylis glomerata L. Y Lolium perenne L.

Abstract

The objective of this study was to evaluate two seed sizes in the physiological quality of orchard grass and perennial ryegrass (Dactylis glomerata L., Lolium perenne L.). The treatments were two sizes of seed (large:LS and small:SS). The variables were: emergence (EM), abnormal seedlings (AS), non-germinated seeds (NGS), establishment (ES), viability (VI), speed of emergence (SE), seedling height (SH), and root length (RL). A CRD with 4 repetitions were used. It was observed that, regardless of the size, the EM was higher in perennial ryegrass (p¿0.05), compared to orchard grass, due to it presenting the highest (p¿0.05) percentage of AS and NGS.
