PDC LESSON 3.16 SEEDS – DARKNESS

 

Darkness

the action of light also has a detrimental effect on seed viability. Put them in paper bags or dark coloured jars or store them in a cupboard.

 

Moisture

excessive moisture will allow the seed to overheat and become like compost. Different seed coat thicknesses will determine how soon moisture will affect seed viability. Most seed need to be stored at 10% or below humidity. (Peanuts and soybeans are best stored at 15% because of their oil content.

At lower moisture levels seed can handle temperature variations better.

 

Silica gel crystals can be bought at chemist stores and will absorb any moisture from the seed in a sealed container. The colour of the crystals will indicate how much moisture has been absorbed. Blue is dry, pink is moist. Dry the crystals in the oven until they turn blue again. Dry rice grains will also do the same job. You can also save silica crystals from shoe boxes and vitamin pills.
