title: [Genetic studies in Picea abies with the aid of isoenzyme identification : II. Genetic control of esterase and leucine aminopeptidase isoenzymes in haploid macrogametophytes of dormant seeds].
abstract: Using techniques of starch gel zone electrophoresis, a considerable variation among esterase and leucine aminopeptidase isoenzyme patterns was found in the endosperm of dormant seeds of Norway spruce (Picea abies). Since the so-called primary endosperm of conifers is only a further developmental stage of the haploid female gametophyte, simple Mendelian segregations can be determined in seeds of individual open-pollinated trees. It was therefore possible to identify some esterase and leucine aminopeptidase loci only with regard to phenotypic frequency distributions without difficult crossing procedures.
