dc.description.abstract | Suncokret (Helianthus annuus L.) je važna uljarica, ali njegovu održivu proizvodnju znatno otežavaju različiti okolišni stresovi, poput suše. Razumijevanje varijabilnosti morfoloških svojstava korijena među različitim genotipovima suncokreta ključno je za odabir onih s prikladnim svojstvima korijena za oplemenjivanje hibrida bolje prilagođenih suši. Ova preliminarna studija dio je projekta SmartSun koji podržava Fond za nauku, Republike Srbije, a nastoji istražiti potencijal postojećih hibrida suncokreta da toleriraju sušne uvjete koristeći visokoučinkovitu fenotipizaciju korijena. Na temelju terenskog promatranja odabrana su dva hibrida (osjetljiv na sušu: NS Danubius; tolerantan na sušu: NS Ronin). Morfološka svojstva korijena u ranoj fazi rasta procijenjena su uporabom platforme za fenotipizaciju u rizotronima pod kontrolom dobrog navodnjavanja (70 % volumetrijski sadržaj vode) i stresom od suše (41-50 % volumetrijski sadržaj vode), nakon čega je uslijedila analiza digitalne slike korijena pomoću WinRhizo skenera. Nekoliko morfoloških svojstava korijena pokazalo se pouzdanim u razlikovanju osjetljivosti na sušu: masa svježeg i suhog korijena, ukupna duljina korijenovog sustava, volumen, površina i promjer. Smanjena stopa rasta i značajno smanjenje izmjerenih parametara otkriveno je za oba genotipa u uvjetima smanjene dostupnosti vode. Dobiveni rezultati prvi su korak u iskorištavanju novih fenomenoloških alata za identifikaciju otpornosti genotipova suncokreta na sušu. | sr |
dc.description.abstract | Sunflower (Helianthus annuus L.) is an important oil crop, but its sustainable production is significantly hampered by various environmental stresses, such as drought. Understanding the variability in root morphological traits among diverse sunflower genotypes is crucial for selecting those with suitable root traits for breeding hybrids better adapted to drought. This preliminary study is part of SmartSun project supported by Fund of Science, Republic of Serbia, and tends to investigate the potential of existing sunflower hybrids to tolerate drought conditions using high-throughput root phenotyping. Two hybrids were selected based on field observation (drought-sensitive: NS Danubius; drought-tolerant: NS Ronin). Root morphological traits in an early growth stage were assessed using a rhizotron phenotyping platform under well-watered control (70% volumetric water content) and drought stress (41-50% volumetric water content), followed by root digital image analysis using WinRhizo scanner. Several root morphological traits were shown to be reliable in differentiating drought sensitivity: fresh and dry root mass, total length of the root system, volume, surface area and diameter. Reduced growth rate and significant decrease in measured parameters was detected for both genotypes under reduced water availability conditions. The obtained results are the first step in exploitation of new phenomics tools for identification of drought tolerance of sunflower genotypes. | sr |
