The pH determines whether a solution is acidic, basic, or neutral by measuring the number of hydrogen ions.
In plants, germination is when a dormant seed starts to sprout and develop into a seedling in the appropriate growing environment.
When a dry seed touches damp soil or growth media, the seed coat begins to absorb water.
The germination rate of seeds from most species was negatively affected by high pH, although the percent germination rate of any species was unaffected.
The higher the nutrient solution concentration, the lower the germination level and pace.
The activity of enzymes in plants is influenced by pH.
Some enzymes may become inactive if the pH level is changed.
It also impacts the availability of nutrients for plants when they are growing in soil.
