Abstract

Determining ploidy level (number of sets of chromosomes) is important for plant conservation. Many species of plants have individuals with more than one ploidy level. Matching plants with the same ploidy levels can be essential for successful plant-restoration projects. The Chicago Botanic Garden is a hub for ploidy determination because of rare access to a flow cytometer, which measures the size of nuclei, and therefore ploidy level, in plant cells. How samples should be submitted is currently unclear. This project examines sample viability in twoE. lanatum populations with different ploidy levels. Results show that extraction of fresh leaf material yields the most accurate results.
