Other claims from this paper (15)
- Intervention effect Salinity stress reduced shoot length, leaf area and dry weight in all three basmati rice varieties.
- Intervention effect Salinity stress reduced photosynthetic rate, chlorophyll content and Rubisco activity in all three basmati rice varieties.
- Observation The reduction in growth and physiological parameters under salinity was largest in HBC‐19, followed by CSR‐30 and Pokkali.
- Observation Cumulative SOD activity increased under salinity in Pokkali and CSR‐30.
- Observation Cumulative SOD activity decreased under salinity in HBC‐19.
- Intervention effect Mn-SOD activity was enhanced under salinity stress in all three basmati rice varieties.
- Observation Fe-SOD, Cu/Zn-SOD and ascorbate peroxidase activities were lower in HBC‐19 than in CSR‐30 and Pokkali.
- Observation Catalase activity was higher in HBC‐19 than in CSR‐30 and Pokkali.
- Observation Gene expression of the SOD isoforms was not necessarily indicative of the corresponding enzyme activities.
- Intervention effect Fe-SOD gene expression showed the maximal enhancement under salinity in HBC‐19.
- Observation Fe-SOD enzyme activity remained low in HBC‐19 despite the enhancement of its gene expression.
- Observation Cu-Zn SOD gene expression showed a marginal increase in all three varieties.
- Observation Cu-Zn SOD activity was significantly higher in Pokkali and CSR‐30 than in HBC‐19.
- Observation Catalase activity in HBC‐19 was significantly enhanced relative to CSR‐30 and Pokkali at 12 dS m −1.
- Mechanism Higher NaCl levels may confer a degree of tolerance to H2O2 stress in HBC‐19 through enhanced catalase activity.
