Abstract

Vrste roda Heuchera L. pripadaju skupini trajnica koje se najčešće primjenjuju za uređenje cvjetnih gredica i kamenjara. Osim cvijeta, posjeduju privlačno lišće, što ih čini zanimljivima kroz cijelu godinu. Pri generativnom razmnožavanju koje je zastupljeno u značajnoj mjeri u proizvodnji trajnica, često dolazi do problema sporog nicanja što poskupljuje troškove proizvodnje, stoga je poželjan što kraći period od sjetve do nicanja. Cilj rada je bio utvrditi utjecaj endomikorizne gljive Glomus mossae na dinamiku nicanja sjemena i razvoj listova kod kultivara Heuchera sanguinea Engelm. 'Metallica'. Sjeme je posijano u prethodno inokulirani supstrat sporama endomikorizne gljive Glomus mossae u dvije različite koncentracije, od 2,5 vol. %, i 5 vol. %. Rezultati istraživanja pokazuju da je endomikorizna gljiva Glomus mossae imala pozitivan učinak na dinamiku nicanja u usporedbi s kontrolom. Pozitivan učinak Glomus mossae izostao je kod razvoja listova, u manjoj koncentraciji inokuluma u supstratu (2,5 vol. %), u usporedbi s kontrolom.<br />Species of the genus Heuchera L. belong to the group of perennials that are commonly used for decorating flowerbeds and rockeries. Besides flowers they possess attractive leaves, which makes them attractive throughout the year. In generative reproduction of a perennials slow germination is often a problem which raises production costs. Therefore, it is desirable to have as short a period from sowing to germination. The aim of this study was to determine the effect of mycorrhizal fungi Glomus mossae in two different concentrations of inoculums on the dynamics of seed germination cultivar Heuchera sanguinea Engelm. 'Metallica'. Seeds was sown in substrate previously inoculated with spores of mycorrhizal fungi Glomus mossae in two different concentrations of 2,5 vol% and 5 vol%. The research results show that the mycorrhizal fungus Glomus mossae had a positive effect on the dynamics of the germination compared with the control. The positive effect of Glomus mossae lacked at the development of leaves, to a lesser concentration of inoculums in the substrate (2,5 vol%), compared with control.
