Abstract:
Three salt tolerant cultivars/lines
(B-557, Culture-728-4 and MNH-156) and three salt sensitive cultivars/lines
(B-1580 (ne), Culture-604-4 and MNH-147) were grown in salinized soil
under greenhouse conditions. Four treatments of NaCl, i.e., 16 (control),
70, 140, 210 mol m-3 were applied after 10 days of initial
growth, and experiment continued till maturity. Determination of ions
at seedling stage showed that the salt tolerant and the salt sensitive
cultivars did not differ significantly in accumulation of leaf. The
salt sensitive cultivars had more concentration of Cl- in
leaves than those of the salt tolerant lines at the highest salt level.
The salt tolerant cultivars had generally higher concentrations of K+,
Ca2+ and K/Na ratios in the leaves than those of salt sensitive
lines at the highest NaCl concentration (210 mol m-3). Ginning
out-turn and fibre fineness increased with the increasing concentrations
of salt, whereas staple length, fibre maturity and fibre strength showed
decreasing trend at higher salt concentrations (140 and 210 mol m-3).
The salt tolerant cultivars/lines had lower ginning out-turn, but better
fibre fineness, higher staple length, fibre maturity and fibre strength
compared with those of the salt sensitive cultivars. The salt tolerance
in cotton is thus associated with higher uptake of K+, Ca2+,
low accumulation of Cl-in
the leaves and low ginning out-turn but higher staple length, fibre
maturity and fibre strength.
