Pollen longevity and viability database: an integrated resource for plant research and conservation

Pollen viability and longevity are key traits in plant reproduction, with implications for gene flow, crop breeding, and ex situ plant conservation. However, published data on these traits remain dispersed across disciplines, languages, and methods, limiting their accessibility and reuse. Here, we present a curated, taxonomically broad database compiling pollen viability over time for 274 vascular plant species extracted from 320 primary publications published between 1962 and 2023. The dataset includes germination- and staining-based viability estimates under defined storage conditions, along with metadata on species identity, experimental design, and pollen traits. To facilitate data exploration and application, the full database is openly available via an online repository and accompanied by an interactive Shiny App that allows users to filter, visualize, and download customized subsets. This resource enables comparative research on pollen longevity and viability across taxonomic groups, environments, and methods, and supports future work in trait-based ecology, conservation planning, plant breeding, and reproductive biology.花粉活力与寿命是植物繁殖的关键性状，对基因流、作物育种及迁地植物保护（ex situ plant conservation）均具有重要意义。然而，目前关于这些性状的已发表数据仍分散于不同学科、语言与研究方法中，限制了其可获取性与复用性。本研究构建了一个经人工甄选整理、分类学覆盖广泛的数据库，整合了从1962年至2023年间发表的320篇原始文献中提取的274种维管植物（vascular plant）的随时间变化的花粉活力数据。该数据集包含明确储存条件下基于萌发法与染色法的花粉活力评估值，同时附带物种信息、实验设计及花粉性状等元数据。为便于数据探索与应用，完整数据库可通过在线数据存储库公开获取，并配套一款交互式Shiny应用（Shiny App），支持用户对数据进行筛选、可视化以及自定义子集下载。本数据集可为不同类群、环境与研究方法下的花粉寿命与活力比较研究提供支撑，并助力基于性状的生态学、保护规划、植物育种及生殖生物学等领域的后续研究。
