Data underlying the publication: First evidence of polyembryony in black mangrove Avicennia germinans.

This dataset contains the information collected on the first day of acquiring A. germinans (black mangrove) seeds. The primary aim of this research is to document the first observed case of A. germinans exhibiting polyembryony, as this phenomenon has not been previously recorded in this species. The type of data is mostly observational: Photographs provide a visual record of the observations detailed in the article, and one-time seed weight measurements are provided to support the hypothesis that a higher weight in mature propagules might be an indicator of polyembryony.

本数据集收录了采集黑红树（A. germinans, black mangrove）种子当日所获取的全部相关信息。本研究的核心目标是记录该物种出现多胚现象（polyembryony）的首例观测案例，因为该现象此前从未在黑红树中被记载。本数据集以观测类数据为主：照片可直观呈现论文中详述的各项观测结果，同时附带单次种子重量测定数据，用于佐证“成熟繁殖体重量较高或可作为多胚现象指示指标”的假说。
