The phylogenetic response of two varieties of Thomas laxton and smooth Mammoth melting to increased concentrations of copper

The experiment was conducted in plastic pots under wiry house conditions to study the effect of soil treatment by sulphat copper concentrations (150,100,75,50,25,0.0) mg /Kg soil on growth and some physiological alterations of two Pea genotypes (Mammoth melting) and (Thomas laxton). These treatment caused significant reduction in growth plant, degree of cell membrane stability, relative water content in the leaves, concentrations of chlorophyll a,b , a+b , carbohydrate and protein in leaves tissues. also notes asignificant increase in the proline accumulation in the leaf tissues in both of them (Mammoth melting) and (Thomas laxton). The shoot and concentration carbohydrate and protein in the type (Mammoth melting) species non effect to in increase cooper sulphates except the concentration (150) mg/Kg soil reduced significan compared with control treatment.
