Information on seed morphology and fruiting phenology related to fitness and reproductive strategy is important for plant ecology and evolution. Although seed morphology is highly variable across years, regions and mother trees even within the same species, seed mass and size are often reported as averages or ranges for each species in existing databases or picture books. Unfortunately, freely available seed trait data for individual seeds are limited. This paper reports data on morphology (seed length, width and height) and dry weight of individual seeds from 129 tree species in Japan. It includes data from 79 genera in 44 families collected from various forests located in cool temperate to subtropical regions in Japan, including species not reported in previous databases. We mainly used seeds from the collections of the Forest Tree Gene Bank Program, but new seeds were also collected. If possible, multiple seeds were collected from multiple mother trees of the same species. This paper also reports data of the sampling month and date, which indicates the fruiting season of trees at the sampling site. By comparing these data to past or future data, we hope that it will aid in understanding the effects of climate change on fruiting phenology.

日本129种树种的种子大小和重量

与适应性和生殖策略有关的种子形态和结果物候信息对于植物生态学和进化很重要。尽管种子形态在不同年份,地区和母树甚至同一物种内变化很大,但在现有数据库或图画书中,种子质量和大小通常被报告为每种物种的平均值或范围。不幸的是,可免费获得的单个种子的种子性状数据有限。本文报道了来自日本129种树种的种子的形态(种子长度,宽度和高度)和干重的数据。它包括来自日本冷温带至亚热带地区各种森林的44个科的79属的数据,包括先前数据库中未报告的物种。我们主要使用森林树基因库计划收集的种子,但也收集了新种子。如果可能的话,从同一物种的多棵母树上收集多颗种子。本文还报告了采样月份和日期的数据,该数据指示了采样地点树木的结实季节。通过将这些数据与过去或将来的数据进行比较,我们希望它将有助于理解气候变化对结果物候的影响。
