The equilibrium moisture contents of seeds of 35 kinds of grasses and legumes were determined for the seed moisture range of 13 to 4%. In comparison with the mean equilibrium moisture values of all seeds tested, the correlation coefficients for every kind of seed tested are highly significant, with r values of .95 to .99. This shows that although a given kind of seed may have a higher or lower moisture content than another kind at a given relative humidity, all kinds of seed tested showed essentially parallel changes in moisture content with changes in relative humidity, at least in the seed moisture range of 13 to 4%. A method is given for using the data presented in forecasting the equilibrium moisture percentage that each kind of seed will reach in a mixture of seeds in a sealed container.
