Synergic effect of salinity and light-chilling on photosystem II photochemistry of the halophyte, Sarcocornia fruticosa
Laboratory experiments were conduced to assess the synergic effect of chilling and light on photosystem II photochemistry of the halophyte, Sarcocornia fruticosa, grown at different salinity concentrations (0, 170, 340, 510 and 1030 mM). Chlorophyll fluorescence was measured after chilling (at 5 °C...

| description | Laboratory experiments were conduced to assess the synergic effect of chilling and light on photosystem II photochemistry of the halophyte,
Sarcocornia fruticosa, grown at different salinity concentrations (0, 170, 340, 510 and 1030
mM). Chlorophyll fluorescence was measured after chilling (at 5
°C in darkness) and light-chilling (at 5
°C and 700
μmol

s
−1) treatments, and after 24
h of recovery (at 20
°C and 75
μmol

°C and 700
μmol
m
−2
s
−1, plants grown with 0 and 170
mM NaCl showed the lowest
F
v/
F
m values, whereas quantum efficiency of PSII (
Φ
PSII) was higher for plants grown at 170 and 340
mM NaCl, these results being consistent after two exposures to chilling treatments. Susceptibility to photoinhibition decreases when low temperature and high light are combined with high salinity. Therefore, populations of
S. fruticosa that occur in arid environments with salinities c. 340
mM could show a higher tolerance to light-chilling. |
