Abstract

Pastrnjak je biljna vrsta iz porodice Apiaceae koja se koristi u prehrani i tradicionalnoj medicini zbog aktivnih spojeva koje imaju korisna farmakološka svojstva. Usprkos prehrambenoj važnosti, klijavost sjemena pastrnjaka je niska, što rezultira neujednačenim usjevima i otežava uzgoj, posebno u ekološkim uvjetima. S obzirom na spomenute izazove, cilj ovog istraživanja bio je utvrditi utjecaj predsjetvenih tretmana na klijavost i energiju klijanja sjemena pastrnjaka. Laboratorijskim pokusom istražen je utjecaj triju predsjetvenih tretmana (destilirana voda, biostimulator Eco Green i ekstrakt od biljnog otpada ) na klijavost sjemena pastrnjaka, uz dva načina sušenja sjemena: između ubrusa i 24 h na sobnoj temperaturi. Rezultati su pokazali da predsjetveni tretmani nisu značajno utjecali na klijavosti sjemena, ali su ubrzali i ujednačili klijanje. Sušenje sjemena smanjilo je nepredvidivost i omogućilo ravnomjernije i brže klijanje. Tretman T11 (ekstrakt od biljnog otpada 24h + sušenje između ubrusa) istaknuo se s najviše proklijalih sjemenki, najmanjim prosječnim vremenom klijanja i najvišim indeksom klijanja.

Abstract (english)

The parsnip is a plant species from the Apiaceae family that is used in nutrition and traditional medicine because of its active components that have useful pharmacological properties. Despite its nutritional importance, the germination capacity of parsnip seeds is low, resulting in uneven crops and making cultivation difficult, especially under ecological conditions. Given these challenges, this research aimed to investigate the impact of seed priming on germination and germination energy of parsnip seeds. The effect of three seed priming treatments (distilled water, biostimulator Eco Green and extract from plant waste) on germination, with two methods of seed drying: between towels and 24 h at room temperature was studied under laboratory conditions. The results showed that seed priming did not significantly increase the percentage of germination, but accelerated and uniform germination. Drying the seeds reduced the unpredictability and allowed a more uniform and faster germination. Treatment T11 (extract from plant waste 24h) stood out with most germinated seeds, the lowest average germination time and the highest germination index.
