Project status update: Phenology and fitness in experimental plot 1

imageHardAtWork.jpg

Experimental plot 1 (P1) encompasses 11 different experiments originally planted with a total of 10673 Echinacea individuals. These experiments include long-term studies designed to compare the fitness of Echinacea from different remnant populations (“EA from remnants in P1”), examine the effects of inbreeding on plant fitness (“INB” and “INB2”), and explore other genetic properties of Echinacea such as trait heritability (“qGen”). In 2014, Team Echinacea measured plant traits for the 5409 Echinacea plants that remain alive and followed the daily phenology of 567 flowering heads. Echinacea began producing florets on July 1 and continued flowering in P1 until August 24. The data collected in 2014 will allow us to estimate the heritability of various traits and assess the lifetime fitness of plants from the numerous experiments.
