Equilibration curves are well-known data sets used for defining acceptable seed storage conditions. The data relates properties of the seed to acceptable atmospheres for storing seeds in air. It represents the combined property of seeds and air. Thermodynamic properties of air are readily available as psychrometric charts and tables.

We propose a new seed characteristic by combining the equilibration data with the properties of air. The proposed seed characteristic is unique to the seed and is presented in graphical form. It relates seed temperature, moisture content, and vapor pressure.

We apply this seed characteristic to hermetic storage. Our model confirms the experimental results that seeds stored in hermetic containers maintain constant moisture content.

We also use the seed characteristic to identify some limiting conditions for viable short and long-term seed storage.
