 In: Georgicon for Agriculture (Hungary). (1989). v. 2(Suppl.) p. 167-177Summary: The effect of moisture in the maize /Zea mays L./ seed at the time of harvesting, and of the interaction of harvest x genotype on the biological value is knows. Little is known, on the other hand, of the influence of increased stand density on the quality of seed. Therefore it was tried to find the influence of the harvest, the spacing and the genotype on the emergence of the seed. The investigations concerning the percentage and intensity of emergence were carried out in a phytotron and in the field with 2 genotypes. These gave different responses to the treatments. It can be accepted, as a general rule, however, that when seeds are harvested with less than 60 o/o dry matter content a considerable deterioration of the biological value must be reckoned with. As a consequence, it can be stated that the genotype-specific technologies of seed production have to be based on the results of investigations completed with the examination of dry matter content at harvest time
