Abstract

-Advance regeneration is frequently inadequate to sufficiently restock the oak component of many bottomland stands, especially on productive sites with high levels of competition. We initiated a study near Beirne, AR to examine the effects of pre-plant control of Japanese honeysuckle Thunberg) and seedling quality on establishment success and vigor of oak reproduction beneath a partial canopy. Nine, 2-acre plots were delineated in the stand that was harvested a residual stocking level of 30 percent in the fall of 1996. Honeysuckle pre-plant control treatments randomly applied to the nine were an Escort application in the spring of 1997, an Escort application in the summer of 1997, and a control (no herbicide application). In 1998, 1-O cherrybark oak (Quercus pagoda Raf.) seedlings were planted at a 12 ft x 12 ft spacing in each treatment plot. One-half of each treatment plot received seedlings with four or more roots 0.04 in. diameter, while the other half of each plot received seedlings with fewer than four lateral roots 0.04 in. The spring application of Escort provided effective control against Japanese honeysuckle, thereby producing potentially promising conditions for oak seedling growth and development. First-year seedling survival and growth did not respond to honeysuckle control treatments. Survival was not related seedling quality, and first-year differences in seedling size were attributed to initial size differences in stock types.
