Data for paper: "Inter-regional hybrids of native and invasive Centaurea solstitialis display intermediate competitive ability" Published in Ecography (2016) with DOI: 10.1111/ecog.02653

Root and shoot biomass of Bromus hordeaceus and Centaurea solstitialis plants from California, Spain, or inter-regional hybrids of both, grown in control pots or in competition with each other. Relative Interaction Indexes were also calculated in order to analyze competitive effects and to plot figures.<br>

本数据集包含来自加利福尼亚州、西班牙的硬雀麦（Bromus hordeaceus）和黄星蓟（Centaurea solstitialis）植株，以及二者的跨区域杂交种的根系与地上部生物量数据；所有植株均种植于对照盆栽中，或处于彼此竞争的生长环境下。此外，为分析竞争效应并辅助绘图，本数据集还计算了相对互作指数（Relative Interaction Indexes）。
