EFFECT OF GAMMA RAYS ON THE GERMINATION OF WHEAT SEEDS AND THE MORPHOPHYSIOLOGICAL PROPERTIES OF ...

The effects of low-dose gamma rays (80 Gy) on the morphometric features of bread wheat at the seed germination stage under salt stress were investigated, as well as changes in the water regime, photosynthetic pigment levels, and PSII 14- and 21-day leaf activity. The study's subjects were seeds from the bread wheat cultivars Mirbashir-1 and Sheki-1. Seeds were subjected to Co60 isotope-emitted gamma rays (80 Gy). The effect of salt on morphophysiological indicators of wheat seedlings was studied by germinating seeds exposed to gamma rays using the roll method. Seeds from each sample were kept on wet filter paper at a constant temperature of 20-22°C for 3 days in darkness, then moved to a photoperiod of 12 hours dark/12 hours light and germinated for 11 days. In the tests, different amounts of NaCl (0, 150, and 200 mmol.L-1) were utilised. According to the findings, gamma rays at an 80 Gy dose partially alleviate the deleterious effects of salt stress on germination capability, shoot and root growth, leaf RWC, photosynthetic pigment levels, and PS II activity.
