Abstract
Produkcija nadzemne biomase tri kultivara bijele djeteline različitoga podrijetla (Jura, Regal i Rivendel ) ispitivana je na dva tla s pH vrijednostima 5,61 i 6,27 te supstratu s pH 7,56. Kod biljaka starih 30 dana utvrđena je ukupna nadzemna biomasa, masa listova i stolona, omjer list/stolona te sadržaj suhe tvari u listovima i stolonama. Dobiven je značajan utjecaj tla na sva ispitivana svojstva osim za omjer list/stolona, sadržaj suhe tvari u listovima i stolonama. U prosjeku za kultivare, biljke su se najbolje razvijale na tlu s pH 6,27, a najlošije na supstratu. Kultivari su se značajno razlikovali u svim ispitivanim svojstvima, osim u omjeru list/stolona. Kultivar Regal ostvario je najniže vrijednosti za većinu ispitivanih svojstava kultivara. Kultivari Jura i Rivendel razlikovali su se u sadržaju suhe tvari u listovima.Above-ground biomass production of three white clover cultivars with different origin (Jura, Regal and Rivendel ) was investigated on two soils with 5.61 and 6.27 pH values and at substrate with pH 7.56. Total above-ground biomass, leaf and stolon mass, leaf/stolon ratio and dry matter content of leaf and stolon were evaluated on 30 days old plants. Significant influence of soil was found for all investigated traits with exceptions of leaf/stolon ratio and dry matter content of stolon. On the cultivars average plant development was the best on the soil with pH 6.27, and worse at substrate. Cultivars significantly differed in all investigated traits with exception of leaf/stolon ratio trait. Cultivar Regal obtained the lowest values of most of the investigated traits. Cultivars Jura and Regal differed from each other in dry matter content of leaf
