Crop management and variety have influence on alkylresolcinol content in triticale grain

摘要

Alkylresorcinols (ARs) from cereal kernels belong to the bioactive components, which are said to have health-enhancing properties. The genetic and agronomic factors have an impact on the growth, quantity and quality of cereal grain yields, so they can also affect the content of ARs in triticale (Triticosecale Wittmack). The purpose of this research was to determine the impact of production technology on AR content in the grains of four winter triticale varieties cultivated under different cultivation systems. The research was conducted in the years of 2010-2014 at the Experimental Station in Osiny (51 degrees 27'N; 22 degrees 2'E), Poland. The experiment was located on a lessive soil (Luvisol), on plots sized 45 m(2) in four replications. The first factor was cultivation system (tillage and no-tillage) and the second factor was type of production technology (integrated and intensive), which was diversified in terms the doses of mineral fertilizers and the intensity of plant chemical protection. The study indicated that the content of ARs in winter triticale grains is mostly determined genetically but it also depends on weather conditions and production technology. This content is the least dependent on soil cultivation system. The highest AR content was recorded for Fredro variety, while the lowest for Pizarro, 444 and 277 mg kg(-1), respectively. Using intensive production technologies favored the accumulation of ARs, especially under abundant rainfall during the tillering, at the beginning of shooting and earring, as well as under limited rainfall during plant ripening. The production of pro-health food of a high content of ARs would benefit the most from using Fredro variety of winter triticale, cultivated in tillage system under intensive production technology.
