Abstract
The objective of this study was to investigate the relative salt tolerance of four eggplant cultivars (Solanum melongena L.) by studying chlorophyll (Chl) fluorescence parameters during the vegetative growth stage under increasing salinity levels. The plants were grown in pots filled with peat under controlled conditions and were subjected to the salt stress ranging from 0 (control), 20, 40, 80, and 160 mM NaCl for 25 days. The results showed that the increasing NaCl concentration affected hardly the maximum quantum yield of photosystem (PS) II. The quantum yield of PSII (I broken vertical bar(PSII)) decreased significantly in 'Adriatica' and 'Black Beauty' under the salt stress. The photochemical quenching decreased in 'Black Beauty' and nonphotochemical quenching increased in 'Adriatica' under the salt stress. The Chl fluorescence parameters did not change significantly under the salt stress in 'Bonica' and 'Galine', revealing their tolerance to salinity. After 25 days of the salt stress, the plant growth was reduced in all cultivars, however, this decline was more pronounced in 'Adriatica' and 'Black Beauty'. Additionally, a significant correlation between the biomass and I broken vertical bar(PSII) was observed in 'Adriatica' and 'Black Beauty'. Our results suggest that I broken vertical bar(PSII) can be used as a diagnostic tool to identify salt-tolerant egg-plant cultivars.
