Impact of chemical and biological seed treatments on germination and the size of wheat seedlings

U cilju utvrđivanja i usporedbe utjecaja dva preparata za tretiranje sjemena - biološkog preparata na bazi Trichoderme (Vital Tricho) i sintetskog fungicida (Maxim Extra 050 FS) - na ozimu pšenicu (Triticum aestivum L.) tretirano je sjeme tri kultivara i stavljeno na klijanje metodom između filter papira (IF). Ukupno je u ispitivanju korišteno 3600 sjemenki, a promatrana svojstva bila su: Energija klijanja [%], Klijavost [%], Duljina korijena [cm], Duljina izdanka [cm] te Odnos duljine korijena i duljine izdanka. Statistička analiza rezultata pokusa pokazuje: (i) kultivari su značajan izvor varijabilnosti po svim promatranim parametrima; (ii) korišteni preparati su utjecali na dimenzije klijanaca; (iii) kultivari su različito reagirali na tretmane u pogledu parametara klijavosti.In order to determine and compare the effects of two seed treatment compounds on winter wheat (Triticum aestivum L.) – a biological compound on the basis of a Trichoderma (Vital Tricho) and a synthetic fungicide (Maxim Extra 050 FS) – seeds of three cultivars were treated and placed on germination by the method between filter paper (BF). A total of 3600 seeds were used for the study. The observed properties were Germination energy [%], Germination [%], Root length [cm], Shoot length [cm] and Ratio between the root length and shoot length. Statistical analysis of the experimental results revealed that (i) cultivars were a significant source of variability in all observed parameters; (ii) both preparations affected seedling dimensions; (iii) cultivars responded differently to treatments in terms of germination parameters
