CO2and Nitrogen, but Not Population Density, Alter the Size and C/N Ratio of Phytolacca americana Seeds

1. Plants can provision seeds by optimizing seed size, number and nutrient content to maximize parental fitness. According to the McGinley-Charnov hypothesis, seed size should be determined by the ratio of carbon to nitrogen (C/N) available to the plant, with larger seed size correlating with larger...
