| Abstract | Bundeve se dugi niz godina koriste kao izvor hrane, ali i u preradi ulja. U Hrvatskoj, obična biljna bundeva koristi se za potrebe dobivanja ulja. Uzgoj se temelji na kvalitetnom sjemenu i obradi tla što u konačnici donosi pogodan plod. Proučavanjem i ispitivanjem klijavosti sjemena, moguće je poboljšanje prinosa i kvalitete usjeva. Cilj završnog rada je utvrditi utjecaj pH vodene otopine na klijavost obične bundeve. Za potrebe istraživanja pokus je proveden u kontroliranim uvjetima unutar laboratorijske klima komore. Za utvrđivanje klijavosti i morfoloških karakteristika klijanaca, sjeme uljne bundeve bilo je ispitivano putem 7 različitih pH vrijednosti vodene otopine (2,5, 3,5, 4,5, 5,5, 6,5, 7,5 i 8,5). Istraživanje je provedeno na ukupno 40 sjemenki u 4 ponavljanja pri izlaganju 7 različitih pH vrijednosti vodene otopine. Prosječna dužina klijanaca u ovom istraživanju iznosila je 7,6 cm. Najmanji klijanci razvili su se u vrlo kiseloj sredini na pH 3,5, gdje je prosječna dužina klijanaca iznosila svega 3,6 cm. Najveći klijanci razvili su se na pH 7,5 gdje je dužina klijanaca bila u rasponu od 9,1 do 11 centimetara. |
| Abstract (english) | Pumpkins have been used for many years as a source of food, but also in oil processing. In Croatia, ordinary vegetable pumpkin is used for obtaining oil. Cultivation is based on high-quality seeds and soil cultivation, which ultimately brings good fruit. By studying and testing the germination of seeds, it is possible to improve the yield and quality of crops. The aim of the final paper is to determine the influence of the pH of the aqueous solution on the germination of common pumpkin. For the purposes of the research, the method of influencing the seeds was used under controlled conditions inside a laboratory air-conditioning chamber. To determine the germination and morphological characteristics of the seedlings, oil pumpkin seeds were tested using 7 different pH values of the aqueous solution (2.5, 3.5, 4.5, 5.5, 6.5, 7.5, and 8.5). By researching a total of 40 seeds in 4 repetitions when challenging 7 different pH values of the water solution. The average length of seedlings in this study was 7.6 cm. The smallest seedlings developed in a very acidic medium at pH 3.5, where the average length of the seedlings was only 3.6 cm. The largest seedlings developed at pH 7.5, where the length of the seedlings was in the range of 9.1 to 11 centimetres. |
