Gene Howe (pink-flowered A. fragrans population) 2021 data

These data are from a pollinator-exclusion study conducted by Cecilia Girvin and Eric LoPresti in a pink-flowered population at the Gene Howe Wildlife Management Area in Hemphill County, Texas. In May 2021, Cecilia excluded floral visitors from visiting inflorescences during the day and/or night by covering inflorescences with drawstring bags. Four pollinator-exclusion treatments (with a random order) were alternately assigned to inflorescences: open to pollinators overnight (“N” treatment), open during the day (“D” treatment), open both night and day (“O” treatment), and open never (“C” treatment). Cecilia opened/closed bags every dawn and dusk from the day of first flower until senescence of the inflorescence (usually 4-6 days), when each inflorescence was permanently bagged. While we tagged 360 inflorescences in this population, 322 inflorescences survived on 103 plants. All collected inflorescences (~3 weeks later) were scored for pollination success by Cecilia Girvin and Sierra Jaeger, by whether each flower produced a seed or not. Individual columns in the dataset are further described in the associated R script, titled "A. fragrans pollination experiment 2021 analysis script".

本数据集源自Cecilia Girvin与Eric LoPresti开展的传粉者排除（pollinator-exclusion）实验，实验位点设于德克萨斯州Hemphill县Gene Howe野生动物管理区内的粉色花种群中。2021年5月，Cecilia通过抽绳袋遮盖花序（inflorescences）的方式，阻断日间和/或夜间的传粉者造访目标花序。研究共设置4种传粉者排除处理，按随机顺序交替分配至各花序：夜间开放供传粉（"N"处理）、日间开放供传粉（"D"处理）、昼夜均开放供传粉（"O"处理）、完全封闭禁绝传粉（"C"处理）。自首朵花开放当日起，Cecilia每日黎明与黄昏时分开合抽绳袋，直至花序衰老（通常持续4至6天），此后将所有花序永久遮盖。本研究团队在该种群中共标记360个花序，最终103株植株上存活322个花序。约3周后收集全部存活花序，由Cecilia Girvin与Sierra Jaeger依据单花结籽情况，对传粉成功事件进行评分。数据集各列的详细说明见配套R脚本《A. fragrans pollination experiment 2021 analysis script》。
