New Resource for Understanding Seed Longevity

[Dustin Wolkis]

Aloha CPC!

I just wanted to share this new paper published open access which demonstrates a method for modeling seed longevity using the free software R to fit the seed viability equation. Before this  publication, no comprehensive “how-to” guidance was available. We provide R code for three scenarios; 1) fitting a single survival curve, for a single seed lot stored in a constant storage environment; 2) for fitting multiple survival curves and evaluating the effect of constraining parameters for the different treatments/species/accessions; and 3), to model the moisture relations of seed longevity. The methods outlined in the paper can also be applied to model the longevity of pollen and fern/bryophyte spores. We hope this resource will be valuable for those interested in seed longevity, including seed bank managers/curators, species managers, and land managers.
