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.
