Plant Introduction| Zusammenfassung: | Individual variability of natural and empty seeds percentage in 41 Picea abies trees has been studied on the basis of the Donetsk botanical gardens primary artificial tree-stand. The groups of trees characterized by a high full-seeds percentage (87%) and by the large portion of empty seeds (81%) have been singled out. Genotypic peculiarities of these trees have been revealed using 20 allozime loci encoded 9 gene-enzymous systems. An excess of heterozygotes of 11% and the heterozygosity level of 21,7% – higher than the mean value for the population (18,4%) – were characteristic of the trees with the maximum amount of full seeds. The individuals with a low heterozygosity (5%) were characterized by a high percentage of empty seeds (58%). |
