Seeds of sugar beet, barley, maize, lettuce and rape were rinsed in deionized water and then soaked in 5% NaOCl for disinfection. For germination test, 3 to 7 seeds were immersed on 1% agar plate with 50 mM NaCl and pH indicators. Bromocresolpurple with 1 mM NH4Cl and bromocresolblue with 1 mM NaNO3 were used to detect the pH changes during the germination on agar plate in the range from 6 to 4 or from 4 to 6, respectively. The germination of monocots was rapidly progressed comparing to dicots. It was clearly observed that sugar beet, barley and rape were tolerant to salt stress at least during the germination stage. Similarly, young seedlings were immersed into 1 % agar medium with 50 mM NaCl and pH indicators. Rhizospheric pH changes were to be observed for 72 hours. The pH changes near root were detected within 2 hours. We have tried to identify precisely rhizospheric pH changes with some other pH indicators. Colors were transformed to numeric values on Photoshop program using digital camera and then statistically evaluated. Numeric values were closely correlated with pH values. Thus, we would conclude that germination and young seedling tests on agar plate with pH indicators can rapidly detect the rhizospheric stress. Key words: germination test, rhizospheric pH, screening, salt stress.
