The current study considered responses of mangrove seedlings under low and medium
saline conditions over only 14 weeks. Such a short period may be insufficient to reveal
slowly developing responses (BALL et al., 1997). Nevertheless, rapid responses to soil salinity
during the early growth of seedlings may be important determinants of their survival.
As an example, B. sexangula showed a severe inhibition (i.e., 45%) of its dry mass under
medium compared with low salinity conditions after three months of growth, hence further
growth and development is also likely to be impaired, particularly once the initial food
reserves in the propagule are exhausted. It has been reported that viviparous species perform
better than non-viviparous species in seedling establishment, implying the beneficial effects
of propagules in early growth (YE et al., 2005)
