Abstract

ince excess salt in the growing medium can be considered as one of the adverse factors for plants,
plant resistance to salinity acquires the additional interest. Increased drought can affect the development
of the plant at any stage of ontogenesis, and soil salinity affects the plant from the very beginning of its
life. Therefore, the ability of the plant to survive and develop at an early stage in conditions of elevated
salt concentrations is one of the most important biological features, and the growth reaction of sprouts
to stressful conditions is one of the visual indicators of their metabolism changes. Therefore, the aim of
this work is to study the influence of salt stress on the growth reactions of chickpea sprouts. Chickpeas
(Cicer arietinum L.) is an important agricultural and drought-resistant leguminous crop, which is able to
produce good yields in harsh conditions, but this crop is very sensitive to salinity. The effect of NaCl
solution in concentrations of 0.6 and 1.26% on 10 - day chickpea sprouts was studied. Growth, biomass accumulation, anatomical features of shoots and roots of chickpea sprouts under experimental and
control conditions were evaluated. It was experimentally revealed that salt stress had a negative impact
on the growth and biomass accumulation both above-ground part of seedlings and root. Under the influence of salt stress significantly decreased water content in plant bodies. A number of negative changes
in the anatomical structure of the stem and root of young plants were revealed. Negative changes were
intensified with the increase in the degree and time of stress.
Key words: chickpeas (Cicer arietinum L.), salinity, growth reactions, chickpea sprouts, anatomical
parameters.
