Coleoptile length under soil compaction as a percent of length under no compaction was used to measure coleoptile strength. Varieties that produced long coleoptiles under no compaction produced the longest coleoptiles under compaction. Correlations were found between cell diameter and several morphologic structures of the coleoptile. As soil compaction increased, coleoptile length was reduced; total plants emerged and rate of emergence also decreased.
