The effect of excess salinity on plants 

With the exception of a few plants, all plants usually grow in areas with low salinity water and soil. This natural distribution of plants can already tell us what conditions are good for plant growth. 

By now, we know that most plants do not grow where we have a high concentration of salt in soil and water. 

Research has been done on many plant species to find out how tolerant they are to the excess salinity of soil and water. The result of such research can help us select the right type of plants for certain water and soil conditions.

 Project description:
In this project you will perform experiments to identify the effects of different rates of salinity on certain plant species. You may optionally want to perform your experiments on two different species of plants and compare the results.
This is a senior level project similar to the primary level project PX078. Select this only if you are in grades 9 to 12.
