Abstract
The effects of NaCl on the growth, the number of salt gland and salt secretion ofAeluropus littoraliswere studied at different NaCl concentrations. Results showed that with the increase of NaCl concentration, the growth ofAeluropus littoraliswas inhibited and MDA content increased gradually. With the increase of NaCl concentration, fresh weight, dry weight of single plant decreased, andA. littoralissalt secretion increased significantly. Salt gland density was significantly higher with the increase of NaCl concentration, and the total number of salt glands on the low surface was more than that on the upper surface. At the same time, the average secretion rates of individual salt glands increased. These showed that the salt glands could effectively secrete salt outside the body to keep normal physiological function.
