Abstract
To study the response and tolerance of the osmotic regulation substances in tomato seedlings to Cd-Pb stress.A sand culture experiment was conducted to investigate the effects of single Cd and Pb and their compound pollution on the contents of osmotic regulation substances in the tomato seedlings.The results showed that the contents of soluble sugar and proline of tomato leaves were increased.The soluble protein were decreased under single pollution of Cd or Pb.Effects of Cd were stronger than Pb.Under Pb and Cd combined stress,Joint actions(JA) were smaller than the sum of independent actions(SIA) for the content of soluble sugar,the pattern of their interaction was strengthening Pb and weakening Cd with low concentration,weakening Pb and Cd with high concentration.JA were larger than SIA for the content of soluble protein,the pattern of their interaction was weakening Pb and Cd,JA were larger than SIA for the content of soluble protein,the pattern of their interaction was weakening Pb and Cd,JA were larger than the SIA for the content of proline with low concentration,the pattern of their interaction was strengthening Pb and Cd,JAs were smaller than the SIAs for the content of proline with high concentration,the pattern of their interaction was weakening Pb and Cd.
