Waxapple (Syzygium samarngense Merr.et Perry) is an
important tropical fruit in Taiwan. The famous producing area is
located on the coast in Pingtung County. Land subsidence and climate
change will tend to soil alkalization more seriously. This study was to
evaluate the effects of NaCl in waxapple seedlings. NaCl salinity
reduced waxapple shoot growth; it may due to reducing relative water
content in leaf and new shoot. Leaf Cl and Na concentration were
increased but K, Ca, and Mg content had no significant difference after
irrigated with NaCl for six weeks. In roots, Na and Cl content increase
significantly with 90 mM NaCl treatment, but K, Ca, and Mg content
was reduced. 3090mM Nacl treatment do not effect KNa, CaNa and
MgNa ratio, but decrease significantly in 90mM treatment in roots.
The leaf and root electrolyte leakage were significantly affected by 90
mM NaCl treatment. Suggesting 90mM was optimum concentration
for sieve out other tolerance waxapples verities.
