Other claims from this paper (18)
- Observation Four regenerants tolerated NaCl up to 80 mM, while the parent tolerated up to 40 mM.
- Intervention effect PSII quantum yield declined significantly in the parent under salt stress.
- Intervention effect Photochemical quenching fell in the parent under salt stress.
- Intervention effect Nonphotochemical quenching rose in the parent under salt stress.
- Intervention effect Regenerants maintained stable chlorophyll fluorescence parameters under salt stress.
- Intervention effect Increasing NaCl raised foliar proline, malondialdehyde and soluble carbohydrates in the parent.
- Intervention effect Soluble carbohydrates declined in regenerants under salinity.
- Intervention effect Starch increased significantly in regenerants under salinity.
- Association Foliar sodium and chloride accumulation was greater in the parent than regenerants.
- Intervention effect Leaf potassium, calcium and magnesium reductions under salt stress were greater in the parent.
- Association Lower foliar sodium in regenerants was associated with higher plant tolerance index and normal growth.
- Association The parent had greater foliar sodium accumulation and failed to maintain normal growth under salinity.
- Observation Regenerants maintained significantly high chlorophyll content under salinity.
- Association Antioxidant enzyme machinery in regenerants performed better in roots than leaves.
- Intervention effect Salt stress significantly increased three peroxidase and catalase activities in regenerant roots.
- Association Parent enzyme activities increased less than in regenerants.
- Association ACC deaminase activity was significantly higher in regenerants than the parent.
- Recommendation The authors consider these stable salt-tolerant regenerants promising selected mutants for eggplant.
