Sažetak

Divlji višegodišnji grašak Vavilovia formosa je reliktna i ugrožena vrsta koja pripada visokoplaninskoj (alpskoj) flori Jermenije i koja je prilagođena kamenitim, siparnim staništima. Populacije V. formosa u Jermeniji, kao i na drugim mestima u svetu, u opasnosti su od izumiranja i zahtevaju komplementarna in situ i ex situ proučavanja i očuvanje. Ovaj rad prikazuje proučavanja populacije V. formosa planine Aknasar, pružajući podatke o prirodnim uslovima, sastavu flore, ekološkim i biocenoznim karakteristikama staništa i bioekološkim obeležjima V. formosa. Sadašnje stanje populacije Vavilovia na planini Aknasar je zadovoljavajuće. Pored vegetativnog razmnožavanja, primećeno je aktiviranje razmnožavanja semenom. Jedna od prirodnih pretnji koja dovodi do promena i smanjenja populacije Vavilovia je obrastanje staništa pokretnog sipra busenastim travama, utičući na stvaranje uslova za razvoj planinsko-livadske vegetacije. Strategija ex situ očuvanja V. formosa je jedan od mogućih načina procene njene sposobnost prilagođavanja na promene spoljašnje sredine, kao i način njenog očuvanja i korišćenja u osnovnim i primenjenim istraživanjima. Započeta ispitivanja mogućnosti gajenja vavilovije u Jerevanu i botaničkim baštama Sevana dala su podatke o njenim biomorfološkim i ekofiziološkim osobenostima u ex situ uslovima.
