The aim of this study is to determine the correlation between the electrical conductivity test, tetrazolium test and hydrogen peroxide treatment. The seed was collected in 12 different seed stands in Serbia that are commonly used for nursery production. The seed sample used for testing was randomly taken from the total amount of the collected seed. The analysis of the obtained results included the calculation of the Pearson correlation coefficient in the statistical software package "Statistica 7". The correlation was determined between the recorded results of the seed weight and the electrical conductivity; the seed weight and the tetrazolium test; the seed weight and the hydrogen peroxide treatment; the electrical conductivity and the tetrazolium test; the electrical conductivity and the hydrogen peroxide treatment; the tetrazolium test and the hydrogen peroxide treatment. Based on the conducted researches it can be concluded that the standardization of the electrical conductivity test using the tetrazolium test and hydrogen peroxide treatment could contribute to a more quality and more comprehensive determination of the beech seed quality for commercial purposes. Key words: Seed quality, seed stands, beech. RAZLIČITE METODE ZA ISPITIVANJE KVALITETA SEMENA BUKVE Abstrakt:U radu su prikazane tri različite metode za testiranje kvaliteta semena bukve. Cilj ovog istraživanja je utvrđivanje korelacijskih odnosa između testa električne provodljivosti, tetrazolijum testa i tretmana semena vodonik peroksidom. Seme je sakupjeno iz 12 različitih semenskih sastojina na području Srbije, koje se uobičajeno koriste za sakupljanje semena za rasadničku proizvodnju. Testirani uzorak je nasumično 1 University of Belgrade – Faculty of Forestry, Belgrade, Serbia 2 Institute of Forestry, Belgrade, Serbia 1 odabran iz ukupne količine sakupljenog semena. Analiza dobijenih rezultata obuhvatila je izračunavanje Pirsonovog koeficijenta korelacije u statističkom programu "Statistica 7". Utvrđena je korelacija između zabeleženih rezultata mase semena i električne provodljivosti, tetrazolium testa i tretmana vodonik peroksidom; električne provodljivosti i tetrazolijum testa i vodonik peroksid tretmana, kao i između tetrazolijum testa i vodonik peroksid tretmana. Na osnovu sprovedenih istraživanja može se zaključiti da standardizacijom testa električne provodljivosti uz primenu tetrazolijum testa i vodonik peroksid tretmana doprinelo bi se kvalitetnijem i bržem utvrđivanju kvaliteta semena bukve u komercijalne svrhe. Ključne reči: kvalitet semena, semenske sastojine, bukva. 1. INTRODUCTION As it is well known, the seed quality is very important in the nursery production from the economic point of view and optimizing storage conditions is one of the major tasks for producers. The seed of the European beech possess a deep embryo dormancy resulting in an enormous seed loss and poor seedling production in nurseries (Muller & Bonnet-Masimbert, 1982). This embryo dormancy inhibits germination of viable, mature embryos even when there are conditions suitable for germination. The dormancy is controlled by environmental, physiological and genetic factors (Milošević et al. 1996). The most common way of storage of beech seeds is in a fridge (at the temperature of about 5o C) in the paper/plastic bags for about six mounts. Sometimes the storage can last longer, which may or may not necessarily reduce the quality of the seeds (Suszka, 1974; Suszka and Zieta 1977; Muller & Bonnet-Masimbert 1982; Muller, 1993; Gosling, 1991; Soltani, 2003). The seed aging processes are controlled by the temperature and the moisture conditions, and may be associated with various chemical
