Abstract: The paper deals with the influence of salinity on the changes in caloric values and ash contents of different parts of Kandelia candel seedlings cultivated for 170 days. The results indicate that the medium salinity had little influence on the caloric values and ash contents of hypocotyls other than those of root, stem and leaf. The caloric values of root, stem, and leaf increased with the salt stress at low salinity, and decreased with the salt stress at high salinity. The caloric values of root, stem and leaf reached the peak under the medium salinity of 15‰,20‰ and 25‰ ,respectively. The medium salinity of 15‰ was the upper limit for the normal living of K. candel The caloric value was a good physiological index for determining salt-resistance of species.
