Abstract
Flowering dogwood (Cornus florida L.) is an important understory tree species that is thought to enhance ecological calcium (Ca) cycling and soil Ca availability through high foliar Ca concentrations and rapid leaf litter decomposition. Calcium is an essential macronutrient in plants, important for stabilizing cell walls and plasma membranes. It is also an ubiquitous intracellular second messenger, helping plants sense and physiologically respond to numerous environmental cues. Analyses of total foliar Ca can be dominated by chemically sequestered Ca, which is not readily available for cellular processes. Thus, analyses of specific foliar partitions of Ca are more closely tied to Ca-dependent processes such as signal transduction. To further develop our understanding of the role of flowering dogwood in ecological Ca cycling, we evaluated foliar Ca partitioning via sequential acidic extractions. We compared Ca partitioning in flowering dogwood to that of white oak (Quercus alba L.), and found significantly more labile Ca in dogwood and a much greater proportion of Ca sequestration in oak. We compared foliar Ca partitioning in white oak at sites with dogwood to that of oaks at dogwood-absent sites, and found significantly greater labile Ca in oaks where dogwood was present. We also investigated the phenological patterns of Ca partitioning and sequestration in flowering dogwood foliage, and found preferential partitioning of Ca into the more labile and physiologically accessible pools throughout the growing season, with minimal Ca sequestration. This work helps elucidate the mechanisms and consequences associated with Ca cycling by flowering dogwood in forested systems.
