[Impact of substrate salinity on caloric value, energy accumulation and its distribution in various organs of Bruguiera gymnorrhiza seedlings].
The study with artificial culture showed that the accumulation of dry matter and energy in Bruguiera gymnorrhiza seedlings was promoted by low substrate salinity, but inhibited by high substrate salinity, which peaked at 10 mg.g-1 substrate salinity. With the increase of substrate salinity, the dry matter and the energy tended to be allocated to the micro-roots and leaves, which are nutrient-absorbing organ and photosynthetic organ, respectively. With the increase of substrate salinity, the changes in caloric values were differed in various organs of B. gymnorrhiza seedlings, and those in leaves could reflect the changes in the salt-resistance of the seedlings.
