Fungal and Soil Inoculation Influence on Seedling Growth and Survival of Black Huckleberry (Vaccinium membranaceum Douglas ex Torr.) and Velvet-Leaf Huckleberry (Vaccinium myrtilloides Michx.).

Plants in the order Ericales, including Vaccinium species, occur worldwide, often growing under harsh, nutrient-poor conditions. Although much is known with respect to the cultivated species V. corymbosum L., the biology and propagation requirements of northern Vaccinium species and their potential for use in reclamation, restoration, and horticulture is unexplored. In this study, three seed provenances each of V. membranaceum and V. myrtilloides were collected and sown on a 60:40 peat:sand mixture. Seedling emergence began 25 days after the sowing date. Seedlings were kept in a controlled environment with 21°/10°C day/night temperature and a 15 hour photoperiod. Subsequent to germination, one-quarter of the seedlings were inoculated with Rhizoscyphus ericae (DJ Read) WY Zhuang & Korf, another one-quarter of the seedlings were inoculated with Oidiodendron maius Barron, and another one-quarter of the seedlings were inoculated with Meliniomyces sp. The final one-quarter of the seedlings were maintained as a control group. In the summer of 2008, seedlings will be planted in garden trials; growth (measured as dry biomass production) and survival will be compared at the end of the growing season. Preliminary results will be presented on germination and survival rates under greenhouse conditions, and on the presence or absence of mycorrhizal colonization following inoculation.
