摘要:

研究植物叶片功能性状对环境变化的响应,有助于揭示植物适应策略,植物叶片功能性状数据库(集)已成为宏观尺度上研究植物适应策略以及宏观生态学研究的重要工具,但在宏观尺度上,仍较缺乏针对某一物种和某一特定生境的植物叶片功能性状数据以供分析研究。我们于2023年7月至8月,采集了广泛分布于贵州省喀斯特地区的先锋树种火棘 (Pyracantha fortuneana),共计93个样点406株植物的8120个叶片,测定和计算了叶片湿重、叶片干重、叶长、叶宽、叶面积、比叶面积等9个形态性状以及叶片碳、氮、磷含量及其计量比等6个化学性状指标,同时采集了93个采样点的土壤样品,测定了土壤有机碳含量、全氮含量和全磷含量,汇编为“贵州喀斯特地区先锋树种火棘叶片功能性状数据集”,数据集包括:(1)功能性状的说明;(2)采样点地理信息及简要环境描述;(3)8120个叶片的形态性状实测数据;(4)406株火棘的叶片碳、氮、磷化学计量特征;(5)93个采样点的土壤有机碳、全氮、全磷含量数据;(6)8120个叶片的形态性状样点平均值。该数据集可以为量化喀斯特地区植物叶片功能性状变异及其对环境的响应提供坚实的数据支持,同时也可以为其他宏观尺度上植物功能性状相关的研究提供数据扩展。

Abstract:

Understanding the responses of leaf functional traits of plants to environmental changes is crucial for revealing plant adaptation strategies. Leaf trait databases have emerged as a crucial tool for investigating plant adaptation and a wide range of ecological studies. However, there is still a lack of large-scale leaf trait data for specific species and habitats, and few regional-scale studies have been reported on plant leaf traits in the karst area. Here, we collected 8,120 leaves from 406 individuals of Pyracantha fortuneana, a pioneer species widely distributed in the karst region of Guizhou Province, at 93 sampling sites distributed in the karst region of Guizhou, Southwest China. We measured and calculated nine morphological traits (e.g., leaf fresh weight, dry weight, length, width, area, and specific leaf area) and six chemical traits (e.g., carbon, nitrogen, and phosphorus content and their stoichiometry ratios). Soil samples were also collected from the 93 sites to determine soil organic carbon, total nitrogen, and total phosphorus content. This dataset, named "A dataset on leaf functional traits of a pioneer species (Pyracantha fortuneana) in the karst region of Guizhou, Southwest China" includes 6 Sheets in Excel format: (1) descriptions of functional traits, (2) geographic information and brief environmental descriptions of sampling sites, (3) measured data for morphological traits of 8,120 leaves, (4) carbon, nitrogen, and phosphorus content and their stoichiometry of 406 Pyracantha fortuneana individuals, (5) soil total organic carbon, total nitrogen, and total phosphorus content of 93 sampling sites, and (6) mean values of morphological traits at each sampling site. This dataset provides a solid foundation for quantifying the variation of leaf functional traits and their responses to the environment in the karst region, and can also serve as a valuable resource for other large-scale studies on plant functional traits.
