Abstract

Vodeće hibridne sorte lubenice odlikuju visoka nutritivna vrijednost i potencijal rodnosti, ali i osjetljivost prema suši i visokim temperaturama te ekonomski značajnim bolestima i nematodama. Radi izbjegavanja navedenih rizika, u uzgoju lubenice preporuča se tehnika cijepljenja presadnica. Cilj ovog istraživanja bio je utvrditi kompatibilnost ranih hibridnih sorti lubenice ('Lady' i 'Early Samantha') s podlogama 'Emphasis' (Lagenaria siceraria) i 'Vitalley' (C. maxima × C. moschata) temeljem učinka cijepljenja na vegetativni rast i tržni prinos. Poljski pokus proveden je na lokalitetu Prkovci tijekom 2018. godine, prema slučajnom bloknom rasporedu u četiri ponavljanja. Jednom tjedno tijekom prvog mjeseca nakon sadnje praćeni su pokazatelji vegetativnog rasta. Na duljinu, promjer i broj listova glavne vriježe više su utjecale podloge. Obje sorte cijepljene na podlogu 'Emphasis' ranije su formirale sekundarne vriježe, imale su više plodova s više šećera nego na podlozi 'Vitalley'. Na broj i masu tržnih plodova značajnije su utjecale sorte plemke nego podloge. Sve kombinacije ostvarile su zadovoljavajući tržni prinos u rasponu od 85,2 t ha-1 (´Early Samantha´ × ´Vitalley´) do 105,5 t ha-1 (´Lady´ × Emphasis´) s razlikom od 19,2 %. Provedenim istraživanjem utvrđena je kompatibilnost između testiranih hibridnih sorti plemke i podloge.

Abstract (english)

Today's leading varieties and hybrids of watermelons are characterized by high nutritional value and fertility potential, but also high sensitivity to drought and high temperatures, as well as economically significant diseases and nematodes. Grafting is recommended in order to avoid these risks. The aim of this study was to determine the compatibility of two early hybrids of the watermelon (´Lady´ and ´Early Samantha´) with rootstocks ´Emphasis´ (Lagenaria siceraria) and ´Vitalley´ (C. maxima x C. Moschata) based on the effect of grafting on vegetative growth and yield. The field experiment was conducted in Prkovci where grafted watermelons hybrids were planted on 12.04.2018. Vegetation growth indicators were monitored once a week for the first month after planting. The rootstocks had more inpact on the lenght, diameter and leaf number of main stem than the hybrids. Both hybrids grafted on rootstock 'Emphasis' earlier formed secondary stems and had more fruit with more sugar than hybrids on rootstock 'Vitalley'. The number and weight of marketable fruits was more significantly influenced by the hybrids than rootstocks. All combinations achieved satisfactory market yields ranging from 85.2 t ha-1 (´Early Samantha´ × ´Vitalley´) to 105.5 t ha-1 (´Lady´ × Emphasis´) with a difference of 19.2 %. This research established the compatibility between tested hybrid varieties scions and rootstocks.
