Özet

  • Anthropogenic activities are intensifying
  • global warming, which in turn is increasingly
  • leading to destructive environmental issues such as
  • elevated temperature, salinity, and drought. It is
  • expected that, due to climate change, the proportion
  • of arable land affected by salinity will increase,
  • thereby exacerbating the threat to global food
  • security posed by a rapidly growing population.
  • Consequently, efforts to reduce yield losses have
  • become a central focus. Wheat is the world’s most
  • important cereal crop in terms of nutrition. It is well
  • established that abiotic stresses, including salinity
  • stress, disturb plant homeostasis and cause nuclear
  • damage. Chitosan (Cht), a signaling molecule, has
  • been shown to mitigate the adverse effects of salinity
  • stress in plants. This study aimed to elucidate the
  • biochemical changes induced by salt stress in wheat
  • and to assess the efficacy of chitosan application in
  • preventing nuclear physical damage. The results
  • demonstrated that salinity significantly affects the
  • levels of superoxide dismutase (SOD), catalase
  • (CAT), and malondialdehyde (MDA), while also
  • increasing the parameters (tail length, tail % DNA,
  • and tail moment) used to quantify nuclear physical
  • damage. Furthermore, chitosan application
  • contributed to improved plant homeostasis and a
    • reduction in nuclear damage.
