Povzetek
Kitajbelovka (Kitaibela vitifolia Willd.), poznana tudi kot balkanski slezenovec, je kritično ogrožena rastlinska vrsta z veliko nevarnostjo izumrtja v naravi. Med drugim je razlog za to majhna sposobnost kalitve, ki jo povzroča dormanca. V raziskavi so bili ovrednoteni kalitev semen in parametri rasti kitajbelovke kot odziv na osem različnih predsetvenih obravnavanj. Odstotek kalitve je bil med 0 % in 55 %, odvisno od predsetvenega obravnavanja. Najučinkovitejša metoda prekinitve dormance kalitve pri kitajbelovki je bilo namakanje semen pred kalitvijo v H2SO4 za 5 min. Mehanska skarifikacija semen je tudi izboljšala kalitev v primerjavi s kontrolo med tem, ko obravnavanji semen z dušikovo kislino in giberilini nista bili učinkoviti pri pospeševanju kalitve. Na vse ovrednotene rastne parametre sejank predkalitveno obravnavanje ni vplivalo. Upoštevaje, da sta uspešna kalitev in uspešen razvoj sejank odločilna za obnavljanje kitajbelovke, je iskanje primernih predsetvenih obravnavanj ključno za pospeševanje kalitve in razvoj sejank te rastline.
