Heirloom versus hybridOpen Pollinated: capable ofproducing seeds that will produceseedlings just like the parent plant.Hybrid: cross-bred compatible typesof plants to create a plant with thebest features of both parents. Manyhybrids will not produce plants withidentical qualities.
Seed GerminationA seed contains the embryo of thenew plant, with a supply of foodfor the embryo until it has formedsufficient roots and leaves toobtain its own food.Imbibition: reactivates enzymes presentin the seed. These enzymes break downstorage compounds in the seed to makethem available for the embryo.Digestion & translocation: enzymes that were synthesized or activated previouslybegin to break down storage material within the seed into simple compounds whichare translocated to the embryo. The embryo begins to grow as cells elongate & divide. Germination: seed continues to undergo metabolic changes which transform the embryo into a seedling.
