摘要

Abstract

Analysis of cold tolerance on mangroveKandelia candel leaf growing in different soil salinity along Jiulong River Estuary in South China showed that the cold tolerance decreased as the increase of soil salinity. The lethal temperatures ofK. candel leaf were −10.4

−9.9 and −8.6 °C in Liaodong

Baijiao and Aotou

respectively. Under 1–2°C cold stress treatment on detached leaves ofK. candel

their caloric value gradually decreased

while electrolyte leakage gradually increased. The leaf's caloric value and electrolyte leakage in Aotou with higher soil salinity varied more largely than those in Liaodong with lower soil salinity. InK. candel leaf

total water content lowered a little

bound water content rose significantly and free water content dropped significantly with duration of cold stress. At the same time

reduction sugar

soluble sugar and starch content gradually decreased and sucrose content gradually increased. Bound water

free water and sucrose content inK. candel leaf from Aotou with higher soil salinity changed more slowly than those from Liaodong with lower soil salinity

but reduction sugar

soluble sugar and starch content inK. candel leaf from Aotou had faster variations than those from Liaodong. These data indicated that soil salinity can reduce cold tolerance ofK. candel leaf by increasing negative effect of salt ions in cell membrane

inhibiting variations of water content

and aggravating consumption of material and energy.
