Dep. of Agron., Pennsylvania State Univ., University Park, PA 16802 USA

View larger version (16K): [in a new window]   Fig. 1 Morphological development (MSC) of high-quality and check alfalfa cultivars during four growth periods. Each data point represents two cultivars over a 3-yr period. MSC is the mean stage by count, where a value of 3 indicates that the majority of stems have 1–2 nodes with buds, but no flowers are present. Cultivar means identified with an * are different at the P 0.05 level of significance

Each data point represents two cultivars over a 3-yr period. CP is crude protein; ADF is acid-detergent fiber; NDF is neutral-detergent fiber; and IVDMD is in vitro dry matter digestibility. Cultivar means identified with an * are different at the P 0.05 level of significance
