The work was developed in Santa Martha farm, in the municipality of Guarne (Antioquia-Colombia), located at 2453 meters above sea level, from October 2013 and July 2014. After 56 days of the uniformity cut was analyzed contents of dry matter (12.74%, 12.90%, 12.45%), protein crude (14.1%, 12.76%, 13.31%), ash (16.19%, 15.50%, 16.00%), calcium (2.86%, 3.05%, 2.93%), phosphorus (0.27%, 0.25%, 0.27%), neutral </span><span>detergent fiber (53.81%, 50.21%, 52.80%), acid detergent ber (48.18%, 48.87%, 48.47%), total nonstructural </span><span>carbohydrates (8.50%, 8.35%, 7.82%), total tannin (0.08%, 0.11%, 0.08%) and total phenols (0.20%, 0.29%, 0.24%), for complete plants harvested in plots established by cuttings, by sexual seed handled </span><span>in vitro </span><span>and by sexual seed handled </span><span>in seedlings, respectively; only differences in total phenols were found (p≤0.05).
