Abstract
Biosphere comprises of various biotic and abiotic stresses in which
abiotic stresses like salinity stress affects the floral productivity. The
broadly observed abiotic stress is salinity stress which plagued soil
fertility, growth and survival of plants. Salinity mainly overexpressed in arid
and semi-arid region that erodes from rocks where water flyoff above yearly
precipitation. Due to excessive salt present in soil and groundwater, the
physiological, biochemical and morphological change take place like stunted
growth, chlorosis, change in shoot-root ratio. Under the influence of salinity,
ion toxicity occurs in plants; as a result of which reactive oxygen species or
active oxygen species release as a byproduct. Nutrients that are present in
soil whose uptake in plants ensures its protection against damage, thus
considered as defense army to plants. To overcome these stresses, plants
utilize mostly these nutrients like; manganese (Mn) and Zinc (Zn) along with
operation of oxidative and antioxidative mechanisms in which various enzymes
gets activated as catalase, peroxidase etc. Legumes are the core element of
imperishable tillage and with its help the productivity and economy persist for
longer period. Legumes are grown more widely in mulching and crop rotation due
to its aptness for nitrogen fixation with communal interaction with rhizobia.
In the present study, we chose two genotypes IPM 2K-14-9 and IPM 410-3 of Vigna
radiata L. (mungbean) and observed it’s morphological and physiological
changes under the concentrations of Mn, Zn against 150mM of NaCl and data
collected for 30 and 60DAT; various parameters were quantified like shoot
length, chlorophyll estimation, relative water content (RWC), electrolyte
leakage (EL), catalase, peroxidase and proline. The outcome of shoot length,
chlorophyll content, RWC were found decreased; whereas the grades of
electrolyte leakage, catalase, peroxidase and proline were found increased,
when treated individually with Mn and Zn, on the other side there was an
increase above mentioned parameters like shoot length, chlorophyll estimation,
RWC and decrease in EL, catalase, peroxidase and proline when cumulative
(Mn-Zn) study was quantified.
