Abstract: (357 Views)
In order to evaluate the effect of L-cysteine and calcium lactate on yield and fruit quality of eggplant (Solanum melongena cv. Greta RZ) under deficit irrigation, a split plot experiment based on randomized complete block design with three replications was conducted at Research Farm of University of Zanjan, during 2021. Experimental treatments were included three levels of irrigation (60, 80 and 100 ETc%) and five foliar spray treatments (two levels of calcium lactate (CaL) 1 and 2 g.l-1 and two levels of L-cysteine (Cys) 0.15 and 0.5%) and distilled water as a control. The results showed that deficit irrigation stress significantly affected plant yield and fruit quality. The lowest fruit number and plant yield (1.8 kg), sepal chlorophyll and vitamin C (11.65 mg.100ml-1) contents, and the highest phenols and flavonoids contents, electron leakage, and Antioxidant enzymes activity were obtained at deficit irrigation 60% ETc. Foliar application of CaL and Cys significantly improved fruit yield and quality under normal and deficit irrigation. The maximum plant yield (4.4 and 3.9 kg), vitamin C content (44.1 and 41.9 mg.100ml-1) and total soluble solid content (4.4 and 3.9 °B) were found with application of CaL 2 g.l-1 and Cys 0.5% respectively under irrigation 100 ETc%. CaL and Cys with increasing antioxidant enzymes activity (superoxide dismutases, catalases and peroxidase) and phenolic compounds led to an increase in fruit antioxidant capacity. According to the results, application of CaL 2 g.l-1 and Cys 0.5% is recommended to improve yield and fruit quality of eggplant under normal and deficit irrigation condition.
