irrigated with 300 mMNaCl (about 22.6% over the
control) (table 3).In stems, the soluble protein content
accumulated markedly up to 50 mMNaCl, and
remained more or less unchanged at the other
salinization levels. The soluble protein content
increased by about 53.3 % at 50mMNaCl.In leaves the
soluble protein content remained more or less
unchanged up to 50 mMNaCl, there after the
inconsistent accumulation has been recorded. In
spikes, the soluble contents increased at most
salinization levels, which was much more prominent
at higher doses of salinization levels (300 mMNaCl
level). In rootsof cv. Gimiza 10, the soluble protein
content enhanced slightly up to 150 mMNaCl and
remained more or less unchanged beyond this level
(table 3). In stems, the soluble protein remained more
or less unchanged up to 150 mMNaCl then, it slow
down greatly, the soluble protein reduced by about
45% at 300 mMNaCl. In leaves, three faces occurred
in the effect of various salinization levels of soluble
proteins in cv.Gimiza10, a-Some promotion occurred
up to 50 mMNaCl. b- A marked and progressive
reduction was recorded at 150 mMNaCl. c-
Asignificant enhancement was obtained at 300
mMNaCl. In spikes the soluble protein content
reduced marginally at the most salinization levels; the
highest reduction about 30% was recorded at the
highest concentrations of NaCl. In stems, the soluble
protein remained more or less unchanged up to 50
mMNaCl, above which a gradual reduction was
exhibited. This reduction approached 30% at 300 mM
NaCl. In leaves the soluble protein remained more or
less unchanged up to 150 mMNaCl, there after some
reduction in soluble protein content was obtained. In
spikes, while salinity stress induced a slight reduction,
if any in the soluble protein.
Table 4 Protein pattern of cv. Sakha 94, cv. Gimiza 11, cv. Gimiza 10 and Giza 168 in response of salinity stress (50 mM, 150 mM
and 300 mM NaCl levels) as compared with control plants.
