Abstract:

Vegetables are essential in human diet and the presence of HM in excess it is a global issue that threaten plant health, wildlife and people [4]. This study was conducted under the protocol OECD 208. And values of Cd and Cu solutions were established in Order no. 756/3 November 1997 with regard to traces of chemical elements in the soil. Chlorophyll pigments evaluation was performed following the protocol of Lichtenthaler (1987) [11]. After data analysis the difference observed between the amount of Chl a and Chl b was very small in all the variants studied. The largest amount of total chlorophyll and the small amount of carotenoids it was determined variant tow (V2 = 100 mg Cu). And coefficient of variation for photosynthetic pigments is not greater than 0.45%.

Keywords:

chlorophyll content, cabbage, Cadmium and Copper toxicity, chlorophyll a, chlorophyll b, carotenoids.
