| Summary: | Genetic-physiological approach was used in the study of the quality of
Serbian spruce seed (Picea omorika /Pancic/Purkyn?), collected in the
populations on the left bank of the river Drina. The seed originated from the
three populations that represent the overall ecological and productive
conditions of Serbian spruce populations in Bosnia and Herzegovina. Two
natural populations were selected: Veliki Stolac and Gostilj, and one planted
forest population in Srebrenica. The cones were collected in late autumn 2009
and early spring 2010. They were collected from five trees from Srebrenica
and Gostilj, and seven trees from Veliki Stolac. Immediately after they were
collected, the cones and seeds were processed and germination tests were
done. Germination, germination viability and germination dynamics were
studied in three categories of seed treatment: 1) control unit (just
processed seed), 2) seed stored for six months at 0-4 ?C, 3) seed stored for
seven months at 0-4? C and treated with fungicide after five months of
storing. The number of germinated seed was observed and noted on the third,
fourth, fifth, seventh, tenth, fourteenth, twenty-first and twenty-eighth
day. There were significant differences in germination dynamics at the
population level and the level of treatment during the first couple of days
of germination test. Fungicide (captan) acted as an inhibitor on seed
germination process. The seeds originating from the largest population of
Veliki Stolac showed the best response to storing treatment with fungicide
related to germination dynamics. The seed originating from Srebrenica andkept
at low temperatures 0-4 ?C without treatment with fungicides showed the best
result in germination. Regardless of the presence of differences in the
dynamics of germination, significant differences in germination regarding
different treatments on the last day of the test, were not recorded.
Kvalitet semena omorike, (Picea omorika /Panc/ Purkyne), iz tri populacije,
na levoj obali reke Drine, u Bosni i Hercegovini analiziran je primenom
geneticko-fizioloskih metoda. Za analize je korisceno seme, iz tri populacije
omorike koje reprezentuju ukupne ekolosko-proizvodne uslove njenih populacija
u Bosni i Hercegovini. Dvije populacije su u delu njenog spontanog javljanja:
Veliki Stolac i Gostilj, a jedna populacija je antropogenog porekla u oklini
Srebrenice. Sisarice su sakupljene krajem 2009. i pocetkom 2010. godine sa
pet stabala iz Srebrenice, sedam sa Velikog Stolca i pet sa Gostilja.
Neposredno nakon sakupljanja sisarice i seme su doradjeni. Energija klijanja,
klijavost i dinamika klijanja ispitivana je kod tri kategorije semena: 1)
sveze sjeme (kontrola); 2) seme skladisteno sest meseci na 0-4?C; 3) seme
skladisteno sedam mjeseci na 0-4?C, sa tim sto je bilo tretirano fungicidom
nakon petog meseca cuvanja. Dinamika klijanja sjemena pracena je treceg,
cetvrtog, petog, sedmog, desetog, cetrnaestog, dvadestprvog i dvadesetosmog
dana. Dobijeni rezultati ukazuju na adaptacioni potencijal omorike za
proizvodnju kvalitetnog semena na ekoloski razlicitim stanistima. Interakcija
uslova stanista i genotipova stabala ukazuju na to da omorika na svojim
priodnim stanistima postize cenoloski optimum, a ne i ekoloski. U sprovedenim
analizama nisu evidentirane znacajne razlike u dinamici klijavosti na nivou
populacija i na nivou tretmana tokom prvih nekoliko dana testa klijavosti.
Fungicid (Captan) delovao je kao inhibitor procesa klijanja semena. Seme
poreklom iz najvece populacije Veliki Stolac, najbolje je ragovalo na tretman
skladistenja sa fungicidom sa obzirom na dinamiku klijanja. Seme poreklom iz
Srebrenice koje je cuvano na niskim temperaturama 0-4?C, bez tretmana
fungicidom, pokazalo je najbolji rezultat sto se tice klijavosti. Bez obzira
na prisustvo razlika u dinamici klijanja, znacajne razlike u klijavosti, u
odnosu na razlicite tretmane, poslednjeg dana testa nisu zabelezene. |
