Synergistic Exposure of Rice Seeds to Different Doses of 𝜸-Ray and Salinity Stress Resulted in Increased Antioxidant Enzyme Activities and Gene-Specific Modulation of TC-NER Pathway

Figure 3

Proline levels in 5-day-old seedlings (a) and 20-day-old plantlets (b) grown from irradiated rice seeds in the absence/presence of NaCl. Chlorophyll content measurements in leaves of 20-day-old rice plantlets grown irradiated seeds germinated on water (c) and 100 mM NaCl solution (d). Both chlorophyll 𝑎 and 𝑏, as well as total chlorophyll content (𝑎/𝑏), were measured. Values are expressed as mean ± SD of three independent replications with 100 seeds for each replication. Significant differences between control and treatments are represented by asterisk (^∗𝑃<0.05; ^∗∗𝑃<0.01). NT: nontreated samples.
