TAILIEUCHUNG - Effect of different irrigation water salinities on some yield and quality components of two field-grown Cucurbit species
Our results show that melon yields decreased as water salinity increased, just as concentrations of glutamic acid content rose, although the concentration of most amino acids did not differ significantly. | L.

Huanghe) and watermelon (Citrullus lanatus. convar megulaspemus) were studied in Minqin Oasis, northwestern China. Our results show that melon yields decreased as water salinity increased, just as concentrations of glutamic acid content rose, although the concentration of most amino acids did not differ significantly. In contrast, watermelon yields decreased significantly as water salinity rose, and fruit number, fruit firmness, fruit crude protein, and essential amino acid (EAA) levels of the watermelon showed a significant increase as water salinity rose. Salt stress on both Cucurbit species resulted in an increase in total soluble solids (TSS) and Na+ concentrations, while Ca2+ and Cl– concentrations were not affected significantly. In conclusion, our results showed that, although melon and watermelon yields were restrained by saline water irrigation, fruit quality was not influenced, such as for the fruit’s amino acids. The fact that saline water irrigation is .
