Abstract
Aim: A study was
conducted to evaluate the salinity tolerance of white jute (C. capsularis)
cultivars.
Methodology: Five white jute
cultivars were assessed for different salinity concentrations (0, 100, 150,
200 and 250 mM NaCl) in a split plot design with three replications per
concentration under greenhouse condition. A total of fifteen plants were
sampled from each treatment ten days after treatment with NaCl to determine
morphological and physiological parameters.
Results: Increased NaCl
concentrations reduced all the morphological and physiological parameters
such as plant height, root length, number of leaves, leaf area, shoot and
root dry weight, relative leaf water content (RLWC), chlorophyll, protein,
proline content, K+ accumulation in shoot and leaves, but water saturation
deficit (WSD) and Na+ contents were increased in the shoot and
leaves.
Interpretation: The study
revealed that among all cultivars assessed JRC-532 and JRC-321 showed
relatively better performance against salt stress whereas cultivar JRC-517
was found more susceptible to salt stress.
Key words: Chlorophyll, Corchorus capsularis, Proline,
Relative water content, Water saturation deficit
