The effect of pre-sowing treatmans on germination of basil (Ocimum basilicum L.)

Bosiljak (Ocimum basilicum L.) je biljka iz porodice usnača (Lamiaceae), a od davnina je poznata kao začinska i ljekovita biljna vrsta. Danas svoju primjenu nalazi u prehrambenoj i farmaceutskoj industriji, proizvodnji parfema te tradicionalnoj medicini. U svrhu bržeg i boljeg klijanja i zasnivanja usjeva u posljednje vrijeme se provodi sve više predsjetvenih tretmana sjemena. Cilj ovog rada je bio utvrditi utjecaj predtremana močenjem sjemena u destiliranoj vodi na klijavost sjemena i početni rast i razvitak klijanaca bosiljka 'Sweet basil'. Ukupno 400 sjemenki bosiljka je bilo izloženo pretretmanima močenja destiliranom vodom tijekom 8, 12 i 24 sata i naklijavano osam dana. Rezultati istraživanja pokazuju kako nema statistički značajne razlike kod ukupne klijavosti, no najveća ukupna klijavost ostvarena je kod tretmana močenjem u destiliranoj vodi tijekom 24 sata (T3) (89 %). Statistički značajno više prosječno vrijeme klijanja (MGT) imala je kontrola (T4). Morfološke karakteristike u vidu duljine korijena te ukupne duljine klijanaca su se također statistički značajno razlikovale. Najveća prosječna duljina korijena i klijanca bila je kod tretmana močenje u destiliranoj vodi tijekom 12 sati (T2) (22,54 mm).Basil (Ocimum basilicum L.) is a plant species from Lamiaceae family, and since ancient times it is known for its medicinal properties and as a spice. Today it is used in the food and pharmaceutical industry, perfume production and traditional medicine. For the purpose of a better germination performance and seedling establishment, nowadays different seed priming techniques have been used. The aim of this diploma thesis was to determine the influence of hydropriming on seed germination and initial growth of basil cultivar 'Sweet basil' seedlings. A total of 400 seeds of basil were exposed to pre-treatment with distilled water through 8, 12 and 24 hours and were germinated for eight days. The results showed that there was no statistically significant difference in total germination, but the highest total germination was achieved during treatment with distilled water for 24 hours (T3) (89 %). The statistically higher mean germination time (MGT) had Treatment T4 (control). Morphological characteristics in terms of root length and total length of seedlings were also significantly different. The highest average length of roots and seedlings was in Treatment 2 (treatment in distilled water for 12 hours) (22.54 mm)
