![]() Moreover, synseeds stored under light conditions and treated with ABA exhibited decreased level of endogenous jasmonic acid what indicated interaction between those two phytohormones at a low temperature. Biochemical parameters showed that ABA effectively reduced the negative effect of the cold stress, what was found on the basis of analyzes of H2O2 and TBARS levels in the stored material. ABA clearly inhibited growth of the encapsulated shoot tips also during cold storage. The preculture of shoot tips on the medium supplemented with ABA led to a decrease in the shoots proliferation rate and inhibition of their growth. The obtained results indicated that darkness was much more favorable condition for synseed storage and did not generate additional stress during cold exposure in contrast to the light conditions. pieninicum storage in the form of synthetic seeds under slow-growth conditions in combination with ABA treatment, as one of the ex situ protection methods of this species. The aim of this study was to investigate the possibility of T. is listed as critically endangered species, for which currently applied protection methods are insufficient. Understanding the underlying mechanisms of nanoparticles in abiotic stress tolerance will open the doors for further improvements in the yield, production and quality of main crops facing the changing environmental challenges. In this review, a glimpse of how nanoparticles could mitigate the negative impacts of salinity or drought stress on plants at the physiological, biochemical and molecular levels is elucidated and discussed. Nanoparticles are being used to deliver nutrients to plants, overcome plant diseases and pathogens and to sense and monitor trace elements present in soil. Tremendous promising techniques are being used to enhance plant abiotic stress tolerance, including the applications of nanoparticles, which are thought to enhance plant performance under stress conditions. Plants combat these adverse abiotic stress impacts via evolving a variety of physiological, biochemical and molecular mechanisms. Among these challenges are abiotic stresses, particularly salinity and drought, which contribute to the huge crops yield loss around the world, thereby leading to food insecurity issues. These changes resulted in more complicated challenges facing all living things on earth. Human activities all over the world cause many changes in the environment. ![]()
