Abstract

U svrhu utvrđivanja potencijala primjene biostimulatora tijekom vegetacije na klijavost sjemena paprike (Capsicum annuum L.), u ovom istraživanju prikupljeno je sjeme s biljaka dva kultivara paprike (babura - Šorokšari i rog - Kurtovska kapija) koje su tijekom vegetacije 2019. godine tretirane biostimulatorima Eco Green i Zeogreen. Uređajem CropReporter određeni su parametri klorofilne fluorescencije, a potom je provedena analiza klijavosti po standardnoj metodi za laboratorijsko ispitivanje klijavosti sjemena. U pokusu je sveukupno korišteno 300 sjemenki od svakog kultivara; po 100 sjemenki s biljaka tretiranih sa svakim od dva biostimulatora + 100 sjemenki s biljaka koje tijekom vegetacije nisu bile tretirane (kontrola). Utvrđeno je da primjena biostimulatora Eco Green ima pozitivan učinak na sljedeća svojstva klijavosti: klijavost (G; %), prosječno vrijeme klijanja (MGT; dan), indeks klijavosti (GI), pouzdanost procesa klijanja (U) i prosječnu stopu klijavosti (MR), dok tretman biostimulatorom Zeogreen nije dao statistički opravdane pozitivne rezultate. Tretmani biostimulatorima nisu imali utjecaj na parametar Chl (fluorescenciju sjemena).

Abstract (english)

In order to determine the potential of biostimulant application during vegetation on germination of pepper seeds (Capsicum annuum L.), in this study the seeds were collected from plants of two pepper cultivars (bell pepper - Šorokšari and horn pepper - Kurtovska kapija) which were treated with Eco Green and Zeogreen biostimulants during the vegetation of 2019. With the use of CropReporter, chlorophyll fluorescence parameters were determined, and germination analysis was performed according to the standard method for laboratory testing of seed germination. In the experiment, 300 seeds from each cultivar were used, 100 seeds from plants treated with each of the two biostimulants + 100 seeds from plants that were not treated during the growing season (control). The use of Eco Green biostimulant was found to have positive effects on the following germination properties: germinability (G; %), mean germination time (MGT; day), germination index (GI), uncertainty of the germination process (U) and mean germination rate (MR), while treatment with the biostimulant Zeogreen did not give statistically justified positive results. Biostimulant application did not effect on the Chl parameter (seed fluorescence).
