Abstract
Six clones of Vaccinium angustifolium and two clones of V. mvrtilloides were studied during the winters of 1991-92 and 1992-93. Plants were evaluated for low temperature tolerance of vascular and reproductive tissues. Over the course of the study, there was a significant difference in low temperature tolerance of flower bud tissue with respect to stem position. Terminal buds hardened later and to a lesser degree than did those located lower on the stem. In addition, flower primordia and flowers were evaluated for low temperature tolerance. The initiation of visible bud swelling was not accompanied by a significant decrease in hardiness; however a significant change was evident once the corolla became clearly visible. This report will discuss the significance of these findings as they relate to frost protection.
