T HE germination requirements of the seeds of many crop plants are critical in relation to temperature, moisture, aeration, light, and the interactions of these factors. Crimson clover (TJ’;folium incarnalum L.) has been considered an exception to most of these restrictions on germination, since the seeds from this winter annual crop produce successive volunteer stands through the summer whenever moisture is adequate to induce germination. Spaced-plant-rows are used in the crimson clover improvement program at State College, Mississippi, to evaluate inbred lines, p/ant introductions, and hand pollinated crosses. Uniform germination is especially critical in these studies since genotypes are compared for seedling vigor and developmental morphology. This report describes temperature dormancy in crimson clover seed and outlines a procedure to avoid erratic germination of seed possessing this characteristic.
