In this
study, effect of applied NaCl on growth and stomatal
resistance, proline and total chlorophyll concentrations of
maize plant (Zea mays L. cv: RX 947) was
investigated. The experiment was arranged in a completely
randomized design with four replications under the
greenhouse condition. The experimental soil was salinized
with NaCl at the rates of 0 and 100 mM NaCl. Growth of the
maize plants was inhibited by salinity. Applied NaCl
significantly decreased dry mass of maize plants. Stomatal
resistance and proline concentrations were increased by high
salinity, while total chlorophyll concentration was
decreased. NaCl caused to increase Na and Cl concentrations
of plant.
Key
words:
Zea mays,
salt stress, stomatal
resistance, proline,
sodium chloride. |
