Heavy metals (HM) are considered
as one of the abiotic stressful factors of
environment caused irrational activity of
human-being. We earlier showed
increase of free proline level for sprouts
of wheat cultivars in the response of
HM (2010 - 2014). It is interesting to
compare the obtained data with an
experiments of free proline content in
the 25 wild wheat, introgression forms,
received with the wild genes and faculty
wheat having a metal stress.

Distribution in the accumulation of free proline
in wild, cultural and introgression forms of
wheat in response to heavy metals
It is established that HM cause increase of free proline level
in all genotypes of wheat, and wild and faculty forms are
characterized by higher of proline content even in control.
Specificity in reaction of introgression forms on effect of various
metals is found, the content of proline raised in 2 and more times,
and growth indicators decreased, especially under the influence of
Cu2+, for example at (Bezostaya 1 x Ae.triaristata) x
Komsomolskaya. Zn2+ for several introgression forms caused
stimulation of growth processes that was connected with the
increasing of proline level. Under the influence of Cd2+ there was a
considerable accumulation of free proline in faculty varieties
Intensive and Memory 47 in winter option. W heat cultivars are more
susceptible to the impact of HM, than wild and introgression forms
that is interfaced to growth of intracellular concentration of proline.
It is shown that free proline should be used for differentiation of the
studied wheat on effect of heavy metals.
