Pollen and ovule production data of ancestral and descendant populations of Viola arvensis in four location of the Parisian region

This dataset has been obtained while phenotyping ancestral and descendant populations of four locations of the field pansy (Viola arvensis). Ancestral populations were collected in the field in 90's-2000's and conserved in seedbanks and descendant were collected in the field in 2021. A first generation was grown in common garden in 2021. Using mothers from the first generation, a second generation composed of families of 5 siblings was grown in controlled greenhouses in 2022. We measured pollen and ovule productions in this second generation. Measurements were made following the methods described in this article: https://doi.org/10.1093/aob/mcaf203.

本数据集源自对4个地理种群的田堇菜（Viola arvensis）祖先种群与后代种群的表型分型研究。祖先种群于20世纪90年代至21世纪初野外采集后保存于种子库，后代种群则于2021年野外采集获得。2021年，研究人员在同质园（common garden）中种植了该物种的第一代种群；以第一代种群的母株为材料，2022年在可控温室中种植了由包含5个姊妹株的家系组成的第二代种群。本研究在该第二代种群中测定了花粉与胚珠产量，测定方法遵循下述文献所述流程：https://doi.org/10.1093/aob/mcaf203。
