Five Year Growth Results of Water Oak (Quercus nigra L.) Provenance

A twelve origin, 68 family seed source study for the western range of water oak (Quercus nigra L.) was established in the field in 1982. Five year growth results are highly significant individual family variation for diameter growth and significant origin variation for height growth. No distinct geographic pattern was evident although the middle Mississippi River and middle eastern Mississippi sources were consistently the better sources for both traits. The southwest Louisiana source was overall the best preforming of the origins for height and growth. Keywords: Quercus nigra L., provenance, height growth, diameter growth, genetic variation.
