Seed harvesting and
cleaning techniques fall into two main categories according to whether the
fruits and seeds are dry or wet when mature (actually, a third category exists
of seeds which will die if dried out after maturing... see Preparing Seeds for
Storage).
They are not
modern hybrids, but come from the ancient plant stocks.They are important because hybrids, although
they may be prolific, extra-large, more colorful varieties, or whatever… tend
to be more susceptible to disease and disaster.
Additionally, hybrid seeds are either incapable of
reproducing at all, or incapable of reproducing themselves. Each successive
generation must be re-created in the laboratory garden or test tube.
Today, it’s hard to know whether or not a seed, plant or
crop is a natural one or whether or not it has been genetically altered. If you
are concerned about the as yet unknown and untested consequences of genetically
altered foods, you will want to grow your own from heirloom seeds.
