| Abstract | ||||
| Increasing salinity levels of the two applied types decreased the number of stomata and its density on both surfaces of sweet pepper leaves as compared with control. In addition, NaCl at 4000 mg/L was more effective in this respect followed by NaCl+CaCl2 and CaCl2. On the other hand, pre-soaking sweet pepper seeds in AsA at 50 mg/L or SA at 75 mg/L increased the number of stomata and its density on both leaf surfaces as compared to control and such salinity levels. Moreover, AsA at 50 mg/L proved to be more affected than SA treatment in this respect. | ||||
