摘要：To evaluate physiological changes of Japanese honeysuckle under lead and cadmium stress, pot-plant experiment was adopted to discover heavy metal Pb or Cd single stress and Pb+Cd combined stress on part of physiological parameters of. Japanese honeysuckle. The results showed that under the same treatment, as time prolonged, the content of soluble sugar and soluble protein was decreased, the activity of SOD declined, the amount of free proline and MDA increased and the activity of CAT elevated. Under Pb stress only, total Chlorophyll content rose first and dropped afterwards and POD activity increased, however, under Cd stress only and Pb+Cd stress, both THCL content and POD activity first rose and then declined. In addition, under Pb or Cd single stress and combined stress, as treatment concentration increased, the contents of soluble sugar, soluble protein, free proline and MDA increased accompanied by POD, CAT and SOD activity increased while TCHL content decreased. All these indicate that under certain range of heavy metal stress, Japanese honeysuckle can reduce metabolic disorder plant damage caused by heavy metal stress through increasing osmotic regulating substances of leaves and inducing scavenging system of active oxygen.
