Evaluation location: Iowa, United States. Method: Daucus descriptor data recorded from observation planting Field N-10 at the NCRPIS farm (42 degrees 0 minutes N latitude 93 degrees 30 minutes W longitude).

This study was designed to estimate ion leakage and increase in cell permeability in response to heat stress at the early and late seedling developmental stages of 215 diverse accessions of wild and cultivated carrot germplasm.
