Research Notes : Inheritance of hardseededness in soybean
Is Version Of
Soybean is often characterized by hardseededness or seed impermeability, when the seeds do not imbibe water and they germinate very slowly. Germination period of such seeds is very prolonged for a month or more. Hardseededness is caused by reduced water permeability of seed coat. We meet this character in many plant species, but more often in Leguminosae, Rosaceae, Lilium (Chorniy, 1980).
