Abstract
Rosike (Droseraceae) spadaju u mesojedne biljke. Žive na osvijetljenim, močvarnim staništima siromašnim nutrijentima. Imaju aktivne stupice jer pokretanjem svojih tentakula love plijen. Cilj ovog istraživanja je bio utvrditi kako se tri vrste rosika Drosera aliciae, D. capensis i D. spatulata prilagođavaju različitim uvjetima uzgoja te postoje li razlike između plojki listova koje nose tentakule i peteljki listova. U tu svrhu određivan je udio fenolnih spojeva, udio fotosintetskih pigmenata, fotosintetska učinkovitost te antioksidacijska aktivnost. Veća fotosintetska učinkovitost izmjerena je kod plojki u odnosu na peteljke listova, te je viša kod vrsta D. capensis i D. aliciae uzgajanih u vanjskim uvjetima, a kod vrste D. spatulata u sobnim uvjetima. Veći udio fotosintetskih pigmenata izmjeren je kod plojki u odnosu na peteljke listova, što se može povezati s višom fotosintetskom učinkovitošću. Udio ukupnih fenola, flavonoida i antocijana je viši u plojkama u odnosu na peteljke što je i logično jer se na plojkama nalaze ružičasti tentakuli koji privlače kukce. Udio flavonoida i antocijana viši je u vanjskim uvjetima kod vrsta D. spatulata i D. aliciae, dok je kod vrste D. capensis viši u sobnim uvjetima. Razlike između vrsta ukazuju da osim intenziteta svjetlosti i drugi faktori imaju učinak na udio pigmenata i fenolnih spojeva. Antioksidacijska aktivnost je podjednako visoka kod svih triju vrsta.
Abstract (english)
Sundews (Droseraceae) are carnivorous plants. They live in sunny, wetland habitats, poor of nutrients. They have active traps because they hunt prey by moving their tentacles. The aim of this study was to determined how sundews Drosera aliciae, D. capensis and D. spatulata can adapt to different grow conditions as well as, are there any differences between leaf blades carryng tentacules, and petioles. For this purpose, content of phenolic compounds and photosynthetic pigments, photosynthetic efficiency and antioxidative activity was evaluated. The higher photosynthetic efficiency was measured in leaf blades than petiole, and it was higher in outdoor-growing D. capensis and D. aliciae, and in indoor-growing D. spatulata. The higher content of photosynthetic pigments was in leaf blades, so we can associate it with high photosynthetic efficiency. Content of phenolic compounds, flavonoides and anthocyanins was higher in leaf blades which was expected because there have red tentacles, which attract prey. Content of flavonoides and anthocyanins was higher in outdoor-growing D. spatulata and D. aliciae while in sundew D. capensis, was higher in indoor-growing plants. Differences between sundews species indicate that beside intensity of light, other factors can have the influence on content of photosynthetic pigments and phenolic compounds also. Antioxidative activity is equally high in all sundews.
