Abstract
Povećani salinitet tla jedan je od čimbenika abiotskog stresa koji negativno utječe na rast i razvoj biljaka. Kineski kupus (Brassica rapa ssp. pekinensis) je kultura kupusnjača prethodno okarakterizirana kao umjereno osjetljiva na povećani salinitet tla. Vrste koje su otpornije na solni stres sadrže veće koncentracije fenolnih kiselina od osjetljivijih vrsta. Cilj ovog rada bio je ispitati učinak tretmana fenolnim kiselinama na toleranciju klijanaca kineskog kupusa na solni stres. Klijanci su uzgajani 48 h na podlogama različitog sastava, uključujući NaCl kao stresor (100 mmol dm-3) te fenolne kiseline, salicilnu i sinapinsku kiselinu (1−50 μmol dm-3). Testom inhibicije korijena i mjerenjem biomase dokazan je značajan inhibitorni učinak soli na klijance. Spektrofotometrijski su izmjerene koncentracije prolina kao markera stresa i koncentracije specijaliziranih metabolita u uzorcima. Identifikacija i kvantifikacija specifičnih fenolnih kiselina analizirana je metodom HPLC. Rezultati upućuju na pozitivan učinak tretmana salicilnom kiselinom na klijance kineskog kupusa u solnom stresu.
Abstract (english)
Increased soil salinity is one of the abiotic stresses that adversely affect plant growth. Chinese cabbage (Brassica rapa ssp. pekinensis) is a crop characterized as moderately sensitive to salinity stress. More salt-tolerant species contain higher concentrations of phenolic acids than the more sensitive ones. This work aimed to examine the effect of phenolic acid treatment on the salt tolerance of Chinese cabbage seedlings. Seedlings were grown for 48 h on media of different composition, including NaCl as a stressor (100 mmol dm-3) and salicylic or sinapic acid (1-50 μmol dm-3). The root growth bioassay and biomass measurement demonstrated a significant inhibitory effect of salt on seedlings. The concentration of proline as a stress marker and specialized metabolites in samples were measured spectrophotometrically. The analysis of phenolic acids was done by HPLC method. The results indicate a positive effect of salicylic acid treatment on Chinese cabbage seedlings in salt stress.
