Foliar metabolism and physiology of tulip poplar, black cherry, and sugar maple growing in three different soil series, each with different taxonomic characteristics and chemistry, in the Monongahela National Forest, West Virginia, USA

The purpose of this study was to compare the foliar metabolism and physiology of tulip poplar (Liriodendron tulipifera L.), black cherry (Prunus serotina Ehrh.), and sugar maple (Acer saccharum Marsh.) growing in three soil series, with different taxonomic characteristics and chemistry, all from sites located within the Desert Branch Watershed in the Monongahela National Forest (MNF), West Virginia, USA. In the growing season of 2003, soil samples were collected from nine sites in the Desert Branch Watershed in the MNF. At each site, a soil pit was hand excavated to various depths, and samples of O, and two to four distinct layers from the A, B and C horizons (where found) were collected. Samples were analyzed separately. Data include soil taxonomy characteristics, extrapolated bulk density, soil pH, % organic matter, total nitrogen (N) and carbon (C), exchangeable elements, exchangeable acidity, effective cation exchange capacity (ECEC), and plant available calcium (Ca) and aluminum (Al) extracted in strontium chloride (SrCl₂) all determined by pH meter, C/N Combustion Elemental Analyzer, potentiometric titration and Inductively Coupled Plasma Optical Emission Spectrophotometer (ICP-OES). Within the same time frame, foliage from 10 randomly chosen tulip poplar (TP), black cherry (BC), and sugar maple (SM) was collected from the same nine sites (two of the nine sites were less than 150 feet apart and were considered to be the same for foliar sampling but separate for soil) in an area central to where corresponding soils had previously been sampled. Data include free polyamines, free amino acids, soluble ions, chlorophyll, soluble protein, total N and total elements analyzed by HPLC, ICP-OES, spectrophotometer, and a C/N Combustion Elemental Analyzer.The purpose of this study was to compare foliar metabolism and physiology of tulip poplar, black cherry and sugar maple growing in three different soil series within the Desert Branch Watershed in the Monongahela National Forest, WV.

本研究的宗旨在于对比分析生长于蒙大拿国家森林（MNF）沙漠分支流域内、土壤系列分类及化学性质各异的北美鹅掌楸（Liriodendron tulipifera L.）、黑 cherry（Prunus serotina Ehrh.）及糖槭（Acer saccharum Marsh.）的叶片代谢与生理特征。在2003年的生长季节，于MNF沙漠分支流域的九个地点采集土壤样本。在每个地点，通过人工挖掘土壤坑，采集了来自O层及A、B、C层（如有）的土样，并分别进行测试。数据涵盖土壤分类特征、推算的体积密度、土壤pH值、有机质百分比、氮（N）和碳（C）总量、交换性元素、交换性酸度、有效阳离子交换能力（ECEC）以及以氯化锶（SrCl₂）提取的植物可利用钙（Ca）和铝（Al），所有这些均通过pH计、碳氮燃烧元素分析仪、电位滴定法和电感耦合等离子体光学发射光谱仪（ICP-OES）测定。在同一时间段内，从同一九个地点随机选取的10株北美鹅掌楸（TP）、黑 cherry（BC）和糖槭（SM）的叶样也被采集。其中，两个地点相距不足150英尺，在叶样采集时被视为同一地点，但在土壤采集时则视为独立地点。数据包括游离多胺、游离氨基酸、可溶性离子、叶绿素、可溶性蛋白、总氮和总元素，通过高效液相色谱法（HPLC）、ICP-OES、分光光度计和碳氮燃烧元素分析仪进行分析。本研究旨在对比分析生长于蒙大拿国家森林沙漠分支流域内不同土壤系列中的北美鹅掌楸、黑 cherry 及糖槭的叶片代谢与生理特征。
