Abstract

The growth performance of seedlings of seven species of true mangroves (Avicennia marina, A. officinalis, Bruguiera gymnorrhiza, B. sexangula, Rhizophora apiculata, R. mucronata, and Sonneratia caseolaris) in response to two contrasting salinity regimes, low (i.e., 3–5) and medium (i.e., 25–27), was studied. Species represented all categories relevant to vivipary (i.e., true viviparous species, cryptoviviparous species and non-viviparous species), and included closely related pairs as well as species commonly used in replanting in Sri Lanka. Species could be ranked in descending order of salinity tolerance as A. marina > R. mucronata > R. apiculata >B. gymnorrhiza > A. officinalis > B. sexangula > S. caseolaris, hence taxonomically similar species and those sharing vivipary characteristics may be distant in salinity tolerance.
