dc.description.abstract | The effects of salinity on in vitro growth, morphogenesis, photosynthetic rate (Pn), PSII efficiency (Fv/Fm), and chlorophyll content were investigated in Centaurium erythraea Rafn. Root growth was more adversely affected by increasing NaCl concentration than was shoot growth. High salt concentrations were effective in induction of axillary and adventitious buds on shoots, with 400 mM NaCl being the most efficient one. Values of Pn and Fv/Fm increased at moderate salt levels, but decreased when 400 mM NaCl was applied. Chlorophyll a and b contents and total chlorophyll had a decreasing trend with increasing supply of NaCl in the growth medium. . | en |
dc.description.abstract | Praćen je efekat NaCl (u rasponu koncentracija od 0 do 400 mM) na rast, morfogenezu, intenzitet fotosinteze (Pn), efikasnost fotosistema II (Fv/Fm) i sadržaj hlorofila a i b kod vrste Centaurium erythraea Rafn. u in vitro uslovima. Utvrđeno je da su koreni kičice osetljiviji na visoke koncentracije soli u hranljivoj podlozi u poređenju sa izdancima. Visoke koncentracije soli su se pokazale efikasnim u pogledu indukcije formiranja aksilarnih i adventivnih pupoljaka na izdancima. U uslovima umerenog stresa (100 i 200 mM NaCl), vrednosti Pn i Fv/Fm rastu u poređenju sa vrednostima dobijenim kod kontrolne grupe biljaka. Primena 400 mM NaCl dovela je do opadanja vrednosti Pn i Fv/Fm ispod kontrolnih vrednosti. Sadržaj hlorofila a i b, kao i ukupnog hlorofila opada sa porastom sadržaja soli u hranljivoj podlozi. Odnos Chl a/b takođe opada. Može se zaključiti da je Centaurium erythraea Rafn vrsta koja je otporna na povećani salinitet podloge u kojoj raste. Prema tome, može se pretpostaviti da je komercijalno gajenje ove vrste kičice ostvarivo na zaslanjenim terenima. . | sr |
