Abstract
Live oak cuttings were successfully propagated during the 1974, 1975, and 1976 spring-summer growing seasons. Stem-tip cuttings from juvenile wood treated with IBA and placed under intermittent mist for 12 weeks exhibited the highest rooting rates of all combinations of cutting wood and propagation methods used. Adult wood rooted poorly, and rooting of cuttings decreased as tree age increased. The application of IBA was essential to rooting of stem-tip cuttings of both juvenile and adult wood. Wardian cases, bench grafting and side-veneer grafting proved to be less useful methods of asexual propagation, and girdling of adult wood was unsuccessful. Root cuttings produced shoots in small numbers. Propagules rooted 2 years previously as cuttings from a desirable field tree were used successfully for new cutting wood. These new cuttings, treated with IBA rind placed under mist, rooted at significantly higher rates than cuttings from the original field tree. Apparent heterozygosity in seeds may have accounted for differences in rooting rates of cuttings from certain seedlings. High, intermediate, and low rates of rooting among selected trees remained constant over 2 summers of collection. Cuttings taken during the winter season rooted poorly. Dates of collection during the spring-summer season had no significant effect on rooting of juvenile or adult cuttings. Selected clones which are easily rooted, exhibit superior phenotypes, and have other desirable qualities will be further propagated and registered as new cultivars of Quercus virginiana Live oak seeds lost viability as they were dried. A moisture loss of 15% reduced viability to 66%, and a moisture loss of 20% reduced viability to 4% in lots of 100 seeds each. Seeds were not stored successfully for longer than 3 months. Storage survival was highest in moist media at 5 - 30°C. Seeds stored either dry or frozen were killed within 1 month..
