Germination and growth of wood-poppy (Stylophorum diphyllum) plants from different sources

These files contain data on the germination and growth rates of wood-poppy (Stylophorum diphyllum) grown from seeds collected from two native Canadian populations and purchased from three commercial seed companies. S. diphyllum is listed as endangered in Canada under Canada's Species at Risk Act. We warm moist stratified all seeds for 2 months and then cold moist stratified them for 2 months prior to sowing. We measured germination rates and time to germination for seeds from each source. We then transplanted seedlings into individual pots and measured the height of each plant and the number of leaves periodically. These data are associated with the article, "Comparing the germination, growth, and morphology of native Canadian and commercially-sourced seeds of wood-poppy (Stylophorum diphyllum)" by Reiter and McCune (2023). We used the data to investigate differences in germination and growth rate between S. diphyllum plants from Canadian populations and plants of United States provenance obtained from commercial seed companies.

这些文件包含从加拿大两个本地种群采集的种子及三家商业种子公司购买的种子所培育的木罂粟（Stylophorum diphyllum）的萌发率与生长速率数据。S. diphyllum在加拿大《濒危物种法》下被列为濒危物种。我们在播种前对所有种子进行了2个月的温湿层积处理，随后进行2个月的冷湿层积处理。我们测量了各来源种子的萌发率及萌发时间，之后将幼苗移植至单独花盆，并定期测定每株植物的高度与叶片数量。这些数据与Reiter和McCune（2023）发表的文章《比较加拿大本地与商业来源木罂粟（Stylophorum diphyllum）种子的萌发、生长及形态特征》相关联，旨在研究加拿大种群的S. diphyllum植株与商业种子公司获取的美国原产地植株在萌发率及生长速率上的差异。
