Sažetak
In this paper, the influence of climatic conditions on accumulation of α -acids was determined during the six years of stationary experiment in hop cultivar Aurora (2001 – 2006). The research results shows that increasing sum of effective temperatures during the technological maturity stays in negative correlation with accumulation of α -acids in hop cones (r = - 0.39*), whereas total rainfalls stays in positive one (r = 0.46*), at the same time sum of hours of sun shining stays in not significant negative correlation with the accumulation of α -acids (r = - 0.38). The results of factorial analysis shows significant positive multiple correlation between sum of effective temperatures and total rainfalls on α -acids accumulation (multiple r = 0.6232**) and at the same time a significant positive multiple correlation between total rainfalls and sunshine hours on α -acids accumulation (multiple r = 0.5492*). However, it was obtained a very strong negative influence of reference crop evapotranspiration during the phonological phase of hop cones formation on yield of hop cones and of α -acids (rs = - 0.75* and – 0.88*, respectively). The total rainfalls during the hop vegetation in interval of [212.1 ; 391.8] mm and also the sum of effective temperature in interval of [1601.74 ; 2000] º C cause the α -acids accumulation in hop cones of cultivar Aurora in interval of [7.41 ; 12.35]% in dry matter. It is important to point out that the level of provided tillage, plant protection measures and fertilization was the same in all six experimental years, which exclude their effects on accumulation of α -acids. These results could possibly contribute in creating a model of predication of α -acids accumulation and beginning of hop harvest.
