Abstract:

In this research, different concentrations of cadmium, nickel, copper heavy metals applied on 10 weeks old Solanum lycopersicum Mill. cv. invictus seedlings by irrigation water. As a result of heavy metal applications total protein amount and peroxidase [EC 1.11.1.7] enzyme activity has been determined by spectrophotometrically. Changing in total protein amount and peroxidase activity in S. lycopersicum seedlings after heavy metal applications has been compared with control group. Depending the application of heavy metals on S. lycopersicum seedlings total protein amount decreased as 57% in 100 ppm of copper application and 10,9% increased in 10 ppm nickel application. The highest increases in peroxidase activity 100 ppm of copper applied and in proportion as 536,03% and treated group with 10 ppm nickel in proportion as 5.97%were determined.
