ABSTRACT
Salt stress is one of the most
serious limiting factors for crop growth and production. This study was carried
out to evaluate the effects of salt stress in four Mentha
piperita L. varieties, in greenhouse conditions. The seedlings
were irrigated with ½ Hoagland nutrition solutions. Following 10 d of growth in
the pots, the seedlings were subjected to salt stress with different
concentrations of NaCl (0, 50 and 100 mM, respectively).
Responses of the mint varieties to salt stress were evaluated using some plant
growth and physiological parameters, such as plant height, root length, shoot and root
fresh and dry weight, and ion concentrations in leaves, such as Na, K, Ca and Cl. Salt stress caused
reduction in physiological parameters. However, this reduction was significant
at 100 mM NaCl compared to 50 mM NaCl. These two concentrations of NaCl
increased Na and Cl contents in leaves. However, K and Ca contents were
decreased with salinity. The results showed that Mentha piperita cv. Sewiss and Granada were found more tolerant to
salt stress than cv. Marokko and Citaro.
