A study of adaptation for late planting. Biennial and annual Melilotus were direct-seeded in field SF-2 on September 16, 2011 for over-wintering observations in 2012. One-hundred hand-scarified seeds of each accession were planted in rows 2.1 m long. The plants were counted on October 25, 2011, these are the sample size data (emergence was uneven). The surviving plants were counted on March 29, 2012. In three cases the percent survival was greater than 100% because of what must have been under-counting plants in October. Since these plants over-wintered in the field the data are more representitive of agricultural conditions than plants that were transplanted into the field in the spring of their flowering year.
