20.500.12556/RUL-188142 Biostimulativni učinek izvlečkov alg na pekočino čilijev Biostimulatory effect of algae extracts on chili pungency Pridelava čilijev je pogosto izpostavljena abiotskim stresnim dejavnikom, ki vplivajo na rast rastlin, pridelek in kakovost plodov, vključno z vsebnostjo kapsaicinoidov, ki so odgovorni za pekočino. Zaradi potrebe po trajnostnih pridelovalnih pristopih se vse več pozornosti namenja uporabi biostimulantov, med katerimi pomembno mesto zavzemajo izvlečki alg, saj lahko izboljšajo izrabo hranil, povečajo odpornost rastlin na stres ter vplivajo na kakovost pridelka. Namen diplomskega dela je bil sistematično pregledati in ovrednotiti raziskave o vplivu algnih izvlečkov na rast čilijev in kakovost pridelka, predvsem na vsebnost kapsaicinoidov pri čilijih različnih vrst rodu Capsicum. Pregled vključuje znanstvene članke o uporabi izvlečkov zelenih, rjavih in rdečih alg ter komercialnih algnih pripravkov, ki so bili najpogosteje uporabljeni v obliki foliarne aplikacije. Ugotovljeno je bilo, da algni izvlečki v številnih primerih pozitivno vplivajo na vegetativno rast, antioksidativno aktivnost, prehranski status rastlin in pridelek, medtem ko njihov vpliv na vsebnost kapsaicinoidov ni enoznačen. Učinek je odvisen od sorte, uporabljenega pripravka, odmerka, mesta kopičenja kapsaicinoidov v plodu ter pridelovalnih razmer. Na podlagi pregleda literature je mogoče sklepati, da imajo algni izvlečki pomemben potencial za trajnostno pridelavo čilijev, vendar so za zanesljivo usmerjanje vsebnosti pekočih spojin potrebne nadaljnje ciljno usmerjene raziskave. Cultivation of chili peppers is frequently exposed to abiotic stress factors that affect plant growth, yield and fruit quality, including the content of capsaicinoids responsible for pungency. Due to the need for sustainable production practices, increasing attention is being paid to the use of biostimulants, among which algae extracts play an important role, as they can improve nutrient use efficiency, enhance plant tolerance to stress and influence crop quality. The aim of this thesis was to systematically review and evaluate studies on the effects of algae-based extracts on chili growth and yield quality, with a particular focus on capsaicinoid content in chili peppers belonging to different species of the genus Capsicum. The review includes scientific articles on the use of extracts from green, brown and red algae and commercial seaweed products, which were most commonly applied as foliar sprays. It was found that algae extracts often have positive effects on vegetative growth, antioxidant activity, plant nutritional status and yield, whereas their impact on capsaicinoid content is not uniform. The effect depends on cultivar, type of preparation, application rate, site of capsaicinoid accumulation within the fruit and growing conditions. Based on the literature review, it can be concluded that algae extracts have considerable potential for sustainable chili pepper production, but further targeted research is needed to reliably modulate the content of pungent compounds. čili biostimulanti alge pekočina chilli biostimulants algae pungency true false false Slovenski jezik Angleški jezik Diplomsko delo/naloga 2026-09-19 07:17:01 2026-09-19 07:17:08 2026-09-21 11:09:17 0000-00-00 00:00:00 2026 0 0 0000-00-00 NiDoloceno NiDoloceno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 290048 291777027 61550.pdf 61550.pdf 1 4B5491E864411FC95A5933C1DB9A4BAB b0128662b3b3355d5a502eda64a33ee0039be3c0cd8a39d0047a591bc83d5122 5277b276-b3e9-11f1-8bc5-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=248169 Biotehniška fakulteta 0 0 0
