Description The present investigation had been done to study the effect of salinity on morphological
and biochemical parameters of sorghum genotypes in stem, leaf and shoot. The plants were
grown in cemented plots with four level of salinity (control, 4, 8 and 12 dSm-1). Morphological
parameters like plant height per plant, number of leaves per plant, fresh and dry weight of stem,
leaves and shoot (g/plant) they all decreased under salinity stress in all genotypes. The
chlorophyll a, chlorophyll b, total chlorophyll, structural carbohydrates (NDF, ADF,
hemicelluloses, cellulose, lignin and silica), protein and IVDMD of genotypes significantly
decreased with increasing salinity levels. HCN content, membrane injury, sugars (total sugar,
reducing sugar and non-reducing sugar), tannins and phenolic content (total phenol, flavanol
and O-dihydric phenol) significantly increased with increasing salinity levels. Macronutrient
like Na and P content increased, and K and Ca content decreased, whereas, in micronutrient Mn,
Zn content increased and Cu and Fe content decreased significantly at each level of salinity in
all the genotypes. On the basis of present study it was concluded that HC 171 and SSG 59-3
may be resistant genotypes, HJ 513 and IS 651 S may be moderate resistant genotypes and HC
260 and HC 308 may be susceptible genotypes.
