DescriptionOpen-pollinated bare-root seedlings from six families of cherrybark oak (Quercus pagoda Raf.), seven families of water oak (Q. nigra L.), six families of willow oak (Q. phellos L.), and eight families of black walnut (Juglans nigra L.) were planted in spring 2003 in nine channels of the University of Missouri Center for Agroforestry Flood Tolerance Laboratory. At onset of budburst, seedlings were left non-flooded or flooded for 5 weeks with 15 cm deep flowing water or stagnant water. A species by flood treatment interaction existed for seedling survival, new shoot growth, and basal sprouting. Based on seedling response, black walnut exhibited the least flood tolerance followed by cherrybark oak, water oak, and willow oak. No significant differences were found for any oak species by partial inundation between flowing or stagnant water flooding. Significant family differences in survival, growth, and basal spouting were found within all three oak species. A strong opportunity exists to make significant genetic gains in field survival and growth on flood-prone sites through selection of flood tolerant seedling families for all three oak species.
