Biochemical Characterization and Responses of Two Contrasting Genotypes of Chenopodium quinoa Willd. to Salinity in a Hydroponic System

Chenopodium quinoa is a promising species for future food security and combating climate change due to its nutritional content halophytic nature. This study focuses on the temporal differential responses of salt-tolerant (Chadmo) salt-sensitive (Kankolla) under control (CK) 400 mM NaCl arranged randomised block designed (RBD). Biochemical features assessed results indicate significant difference (p<0.05) being identified by ANOVA Tukey analyses in total chlorophyll (CHL), carotenoids (CAR), proline, glycine betaine (GB), soluble sugars, K+, Na+, K+/Na+ ratio, Mg2+ Ca2+ both genotypes between CK NaCl. Na+ increased while K+ bivalent ions decreased progressively with time points (CK 24 h) but more pronounced Kankolla. Proline 24.45 18.63% h after exposure Chadmo Kankolla, respectively. Similarly, increases were observed ABA, sugars from genotypes. Using these biochemical salinity, proved be better-performing genotype when exposed hence as genotype.
