Determining cardinal temperatures for eight cover crop species [PDF]
Agrosystems, Geosciences & Environment, 2023 Growing degree days (GDD) is a tool to predict plant growth and can be adapted for use in any plant species, including cover crops. A limitation of the GDD calculation is accurate temperature parameters used to predict plant development.

Field pea cardinal temperatures, growth and vigor traits of winter- and spring-adapted germplasm at germination and seedling stages [PDF]
Scientific ReportsThere are few estimates of cardinal temperatures [Tb (base), To (optimal), Tm (maximum)] for pea (Pisum sativum L.) seed germination and seedling growth traits, with variable results, and there is almost no understanding of how these traits vary among ...

Quantifying cardinal temperatures and thermal time required for germination of Silybum marianum seed
Crop Journal, 2015 The response of seed germination to environmental factors can be estimated by nonlinear regression. The present study was performed to compare four nonlinear regression models (segmented, beta, beta modified, and dent-like) to describe the germination ...
