Abstract
Stablo ginkga, rasprostranjeno je gotovo po cijelom svijetu, otporno je na bolesti, nametnike i onečišćenja, ujedno je dekorativno i ljekovito te danas ima veliki značaj u farmaceutskoj industriji. Radi svojih mehanizama koje prilagođava nastaloj situaciji u okolini u kojoj se nađe, ostalo je nepromijenjeno gotovo više od 300 milijuna godina. Iako je habitualno pravilno oblikovano ravnih grana i zanimljivog lepezastog oblika lista punog hranjihvih tvari s mogućnošću prilagodbe ekstremnim uvjetima, unutar struke krajobrazne arhitekture nije dovoljno iskorišteno. Pretpostavka da može unutar vremena spolnog sazrijevanja, koje kod ove vrste traje 25 godina, promijeniti spol nije do sada dokazana, iako je znanstveno dokazana mogućnost prelaska biljne jedinke iz jednodomne u dvodomnu, na način da dio biljke ili samo jedna grana u tijeku spolnog sazrijevanja promijeni spol. Pretpostavka da je promjena spola moguća kod pojedinih jedinki kada se u prostoru nađu dvije biljke ginkga sađene u paru izvedena je iz promatranja i analiziranja lokacija na kojima su posađeni parovi bez prijašnjeg saznanja o spolu, tj. bez namjernog odabira muške i ženske jedinke unutar para. Od 11 parova, uzorak pojavnosti muške i ženske biljne vrste ogledao se je u 10 slučajeva, dok su kod jednog para pronađena oba muška stabla, no uz pretpostavku evidentiranog i analiziranog panja u blizini, čija kora je identična kori vrste Ginkgo biloba L. te se može pretpostaviti da je nekada postojala možda i ženska jedinka, pa promjena spola kod ostala dva stabla nije bila nužna.
Abstract (english)
Ginkgo tree is spread all over the world, and it is resistant to diseases, pests and pollutants. It's decorative and useful in the same time and today it has great significance in the pharmaceutical industry. It has surviving mechanisms that allow it to adjust to the situation in the surrounding area and because of that it has remained unchanged for almost 300 million years. Although it has habitually properly shaped branches and interesting fan-shaped leafs, it is still not used enough in the profession of landscape architecture. The premise that it can convert sex during the time while it is maturing sexually, which in this species lasts for 25 years, is not proven so far. Regrardless, it is scientifically proven that the possibility of transferring from monoecious to dioecious, in a way that one part of the plant or only one of its branches can convert sex during the maturation period, exists. The assumption that sex conversion is possible in some individuals, when two ginkgo plants are found in one place, is derived from observing and analyzing locations where couples have been planted without prior knowledge of their sex and without choosing male and female ones within a pair. In 11 observed pairs, a sample of male and female plants in a pair was found in 10 cases, while just in one pair both trees were male, but assuming the recorded and analyzed stump in the area, whose bark is identical to the genus of Ginkgo biloba L. it can be assumed that previously there was a single female tree, and so the sex conversion at the other two trees was not necessary.
