Création d'une banque de semences

Seeds naturally have a place in almost any endeavor having to do with agricultural development. Seeds of most food plants are small and, as such, are more easily transported and can be shipped longer distances than vegetative cuttings. For the farmer, seeds represent the promise of a continued supply of food.

As with any development “tool,” however, seeds can be misused. For instance, distributing improperly stored seeds that germinate poorly could expose farmers to risk of crop failure.

This collection is a sub-set of the collection Seed Production and Storage which contains additional resources concerning seeds.  Please feel free to inform us of additional helpful links for either collection.
