2021, 11,five of3. Final results 3.1. Plant Development and Crop Yield Following four weeks from transplanting, the growth parameters decreased substantially only in plants grown at one hundred mM NaCl concentration, except the root biomass fresh and dry matter, which remained unchanged (Table 1). In contrast, two weeks later each of the salt treatment options caused a powerful reduction in both leaf area and leaf biomass (Table 1). With one hundred mM NaCl, the root biomass was also impacted, along with the dry matter content material with the leaves (Table 1). For all the growth parameters, the two-way ANOVA showed no considerable interaction involving NaCl concentration within the nutrient answer plus the sampling time (Table 1). Certainly, the latter had a powerful impact on biomass production, which was considerably larger in older plants. Nonetheless, plant age didn’t affect leaf quantity (Table 1). With NaCl concentrations as much as 50 mM, the fresh yield of younger plants didn’t significantly change and Tianeptine sodium salt supplier averaged 1.86 kg/m2 (Figure 2, left); in contrast, crop yield was drastically reduce (-63 as compared with the control) at 100 mM NaCl concentration. Immediately after six weeks from transplanting, the yield of handle plants was 3.25 kg/m2 and was significantly reduce at each of the tested NaCl concentrations (Figure two, left); the loss of leaf fresh weight was roughly 26 , 37 , and 68 at 25, 50, and 100 mM NaCl, respectively.Table 1.

Leaf Nitrate Content The level of nitrates in the leaves was unaffected by sampling time, regardless of the important influence of salinity (Figure 2, proper). On the other hand, a sturdy interaction in between the two components was identified for the nitrate content, similarly towards the content material of carotenoids and unlike all of the other parameters determined in this perform. Additionally, an incredibly low linear correlation coefficient (0.05) was obtained involving NaCl concentration and the content of nitrate, which was within the range 1500200 mg NO3 – /kg FW. Compared with all the control, the leaf nitrate content was substantially reduce with all the 25 mM treatment at both sampling occasions and with 100 mM NaCl soon after six weeks of cultivation (Figure 2, right).Agronomy 2021, 11, 2352 Agronomy 2021, 11, x FOR PEER REVIEW6 of 12 eight ofControl25 mM NaCl50 mM NaCl100 mM NaCl4amg NO three /kg FWaa b ba a ab bkg FW /mbb c A B AxB ns3000 2000 1000a baa2 1A B AxBFour weeks Six weeks Four weeksSix weeksTime right after transplantingFigure two.
