Abstract Freshly collected bear oak (Quercus ilicifolia Wangenh.) seed from southwestern Virginia exhibited root growth under a range of temperatures but had epicotyl dormancy which was broken by stratification or gibberellic acid (GA3). Shoot elongation resulting from six weeks' chilling or GA3 was also influenced by temperature; a regime of 64°-75°F enhanced both percentage of seed with elongated shoots and leaf area per shoot relative to a 45°-61°F regime. Germination characteristics of seed lots from individual open-pollinated trees varied widely. Results suggest that fall-seeded beds will be most suitable in nursery production and that container stock for spring planting can be produced under greenhouse conditions with fall-stratified seed planted in early January.

Abstract We studied post oak (Quercus stellata Wangenh.) and blackjack oak (Quercus marilandica Münchh.) regeneration in xeric upland oak forests burned from 0 to 5.3 times per decade for 19 years. Post oak and blackjack oak represented 76 and 11% of the site basal area. All reproduction was by sprouting; there were no true seedlings. Compared with post oak, blackjack oak had a substantially higher density of clumps and sprouts relative to its basal area, suggesting that basal area was not a good indicator of sprout production capacity across species. The number of sprouts per clump declined with time since last fire for both species, indicating that fire stimulated sprouting. Three growing seasons after fire, sprouts per clump was highest with the lowest fire frequency and declined with increasing fire. The decline was greatest for blackjack oak. This may have been due to reduced vigor of the root systems producing sprouts with increasing fire frequency. Results suggested that post oak and blackjack oak sprouting, growth rates, and response to fire are similar, but blackjack oak sprout mortality may be higher than that of post oak. This information is important for the maintenance of post oak-blackjack oak-dominated forests of the south-central United States.
