Ginkgo biloba, najstarija i najotpornija drvenasta vrsta na planeti, endemit istoènog dela<br />
Kine, ali od èoveka unet u mnoge zemlje sveta u kojima, kao «ivi fosil» sa izvanrednim<br />
estetskim i znaèajnim lekovitim svojstvima, veoma dobro uspeva. Na Balkan je<br />
verovatno donet iz parkova evropskih zemalja, gde se nalazi još od davne 1730. godine<br />
(Vilotiæ D. 2004). U radu se daju preliminarni podaci o varijabilitetu 5000 kom. sadnica<br />
u rasadniku TAMARIS COMPANY u Banja Luci, proizvedenih iz semena uvezenog iz<br />
Kine. Utvrðena je znatna fenotipska raznovrsnost analiziranih svojstava (rasta i boje<br />
dugorasta, oblika i boje listova u toku leta i dr.) koja je, svakako, samo deo genetièkog<br />
varijabiliteta. Prisustvo individua sa estetskim osobinama nekih veæ poznatih ukrasnih<br />
kultivara ginka, objašnjava se èinjenicom da strane vrste u uslovima kultivisanja, zbog<br />
izmenjenih uslova nove sredine, mogu obrazovati u kratkom periodu niz novih mutanata<br />
(Tucoviæ A. & Ocokoljiæ M. 2002) saglasno zakonu M. I. Vavilova, o paralelnim<br />
serijama nasledne promenljivosti. Utvrðeni varijabilitet je osnova za sintezu atraktivnih<br />
kultivara ginka za potrebe pejzane arhitekture i proizvodnju sve potrebnijih lekovitih<br />
supstanci, a ostvariæe se primenom selekcije, generativnog i vegetativnog razmno-<br />
avanja.<br />
VARIABILITY OF Ginkgo biloba L. SEEDLINGS PRODUCED FROM<br />
THE SEEDS OF CHINESE PROVENANCE IN THE NURSERY TAMARIS<br />
COMPANY IN BANJA LUKA<br />
Ginkgo biloba, the oldest and the most resistant woody species on the planet, endemic of<br />
east China, but anthropogenically introduced to many parts of the world where, as a «living<br />
fossil» with extraordinary esthetical and significant medicinal properties, succeeds<br />
very well. It has probably been brought to the Balkans from the parks of the European<br />
countries, where it occurs since 1730 (Vilotiæ D., 2004). This paper presents the preliminary<br />
data on the variability of 5,000 seedlings in the nursery TAMARIS COMPANY,<br />
Banja Luka, produced from the seeds imported from China. The assessed considerable<br />
phenotypical diversity of the study properties (long shoot growth and colour, leaf shape<br />
and colour during summer, etc.) is by all means only a part of its genetic variability. The<br />
presence of the individuals with aesthetic properties of some known ginkgo ornamental<br />
cultivars is explained by the fact that exotic species in the conditions of cultivation, due<br />
to the changed conditions of the new environment, can form a series of new mutants in a<br />
short period (Tucoviæ A. & Ocokoljiæ M., 2002) consistent with the law by M. I. Vavilov,<br />
on the parallel series of inherited variability. The assessed variability is the base of the<br />
synthesis of attractive ginkgo cultivars for landscape architecture and of the production<br />
of increasingly demanded medical substances and it is going to be realised by selection<br />
and by generative and vegetative reproduction.
