DEPENDENCE OF SERBIAN SPRUCE (Picea omorika /Pančić/Purkyne) SEED QUALITY ON STORAGE TIME

S y n o p s i s

The laboratory analysis of seed quality from 22 test trees of Serbian spruce shows significant differences both between the years of seed collection and between the analysed genotypes. The period of seed storage was not highly significant. Germination percentage of fresh seed in the year of full seed crop at the level of the population was 75.8% and for more than a half of studied trees, it was higher than 80%. The drop in germination percentage after 10 years accounted for 12 % averagely, and in germination energy 19%. Obtained results point to the need of seed tree selection as well as to the possibility of conserving the Serbian spruce seed quality for a longer time period.

Key words: Serbian spruce, seed, germination percentage, quality, genotype, variability

ZAVISNOST KVALITETA SEMENA OMORIKE (Picea omorika /Pančić/Purkyne) OD DUŽINE ČUVANJA

Laboratorijska analiza kvaliteta semena 22 test stabla omorike pokazala je da postoje značajne razlike i između godina sakupljanja semena i između analiziranih genotipova, dok period čuvanja semena nije bio visoko značajan. Klijavost svežeg semena u godini punog uroda na nivou populacije bila je 75,8%, a za više od polovine analiziranih stabala bila je veća od 80%. Pad klijavosti posle 10 godina iznosio je u proseku 12 %  a energije klijanja 19%. Dobijeni rezultati ukazuju na potrebu izdvajanja semenskih stabala kao i na mogućnost očuvanja kvaliteta semena omorike za duži vremenski period.
