Micropropagation of Valley Oak Shoots
Stem segments of valley oak (Quercus lobata Nee) were placed on broad-leaved tree medium (BTM) and Gresshoff-Doy (GD) medium supplemented with 0.55 mg/l of 6-benzylaminopurine (BAP) to observe axillary bud elongation. Both media promoted bud and shoot development, but shoot initiation by explants on GD medium occurred earlier and more abundantly than on BTM medium. Successful shoot development from axillary buds, with subsequent rooting, will permit production of valley oak planting stock from cryogenically preserved woody tissues of parent trees and this will contribute to the preservation of a species currently in decline throughout much of its native range.
