The study looked at how salt stress and cadmium affected the growth of cucumber and tomato plants. They found that when cucumber seeds were exposed to 170 mmol/L of salt and 10 mmol/L of cadmium, their germination rate increased and growth was promoted. However, when the cadmium concentration reached 50 mmol/L, the growth of the roots was inhibited. For tomatoes, even a low concentration of 10 mmol/L of cadmium resulted in no growth, and at 20 mmol/L, the germination rate was only 20% with no lateral roots.
