Abstract

Vegetativno razmnožavanje, razmnožavanje je koje uključuje odvajanje jednog vegetativnog dijela majčinske biljke iz kojeg će se, pravilnim postupcima pripreme i njege, razviti nova biljka genetski identična primarnoj. Coreopsis verticillata 'Zagreb' kultivar je selektiran na Agronomskom fakultetu u Zagrebu. Razmnožava se aseksualno korijenovim reznicama koje se uzimaju u jesen te je u ovome radu ispitivana uspješnost njihovog ukorjenjivanja u zaštićenom prostoru i na otvorenom u dva različita supstrata. Biljke smještene u plasteniku uopće nisu niknule zbog nedostatka niskih temperatura koje su važne za uspješno ukorjenjivanje djevojačkog oka. Na izbojima koji su se pojavili u uzgojnim posudama na otvorenom, mjerena je visina, promjer i broj nodija. Sve tri veličine pokazale su bolje rezultate u supstratu za presadnice iz razloga veće količine dostupnog hraniva.

Abstract (english)

Vegetative propagation is a form of reproduction that involves separating a vegetative part of the mother plant, from which, through proper preparation and care, a new plant genetically identical to the parent will develop. The cultivar 'Zagreb' of Coreopsis verticillata was selected at the Faculty of Agriculture in Zagreb. It reproduces asexually through root cuttings taken in autumn and this study investigates the success of rooting of these cuttings in protected and open space using two different substrates. Plants placed in the greenhouse did not germinate at all due to the lack of low temperatures, which are crucial for the successful rooting of Coreopsis verticillata. However, shoots that appeared in the unheated space were measured for height, diameter, and the number of nodes. All three measurements showed better results in the substrate for seedlings, likely because of the higher availability of nutrients.
