To investigate the synergistic effect of IAA and melatonin (MT) on three plants to alleviate effects salt damage plants, we aim determine optimal concentrations exogenous hormone treatments that improve salinity resistance for each species. In this experiment, desert Sarcozygium xanthoxylon, Nitraria tangutorum, Ammopiptanthus mongolicus, which are common in Wuhai City, were used as plant materials. Two time periods (12 h,24 h) (100 μmol/L) concentration (0, 100, 200, 300 treat saline soil under different conditions melatonin. The results indicate melatonin, germination rate vigor species saline-alkaline improved. However, increased, these inhibited.

Over the years, changes in agriculture industry have been inevitable, considering need to feed growing population. As world population continues grow, food security has become challenged. Resources such as arable land and freshwater scarce due quick urbanization developing countries anthropologic activities; expanding agricultural production areas is not an option. Environmental climatic factors drought, heat, salt stresses pose serious threats worldwide. Therefore, utilize remaining water effectively efficiently maximize yield support increasing demand crucial. It essential develop climate-resilient crops that will outperform traditional under any abiotic stress conditions salt, well these combinations. This review provides a glimpse of how plant breeding evolved overcome harsh environmental what future would be like.

Melatonin (MT) is a crucial hormone that controls and positively regulates plant growth under abiotic stress, but the biochemical physiological processes of combination melatonin seed initiation exogenous spray treatments their effects on maize germination seedling salt tolerance are not well understood. Consequently, in this research, we utilized cultivars Zhengdan 958 (ZD958) Demeiya 1 (DMY1), which extensively marketed northeastern China’s high-latitude cold regions, to reveal modulating salinity by determining impacts varying concentrations characteristics, osmoregulation, antioxidant systems, gene expression. The findings revealed stress (100 mM NaCl) significantly inhibited development, resulted significant increases H2O2 O2− content decreases enzyme activity photosynthetic pigment seedlings. However, considerably reduced development inhibition caused Moreover, alleviated NaCl-induced membrane damage oxidative Na+ excessively large quantities reactive oxygen species (ROS). In addition, increased expression genes ZmSOD4, ZmCAT2, ZmAPX2. This study demonstrates potential role combined foliar mitigating detrimental growth, giving theoretical foundation future research possible advantages regulating chemicals attaining sustainable production salt-alkaline soils.

Seed priming is a simple, inexpensive, and effective pre-sowing technique that enables plants to better tolerate abiotic stresses, including high soil salinity, which major limiting factor in the establishment of halophytes for saline agriculture, as germinating seeds early seedlings many are sensitive compared mature vegetative stage. This article attempts provide an overview research on seed effects halophyte subsequent seedlings/plants. Different physio-chemical molecular processes, induction priming/stress memory, enhance salinity tolerance following priming, have also been discussed. review covers aspects reactive oxygen species (ROS), nitric oxide (NO) signaling(s) activated result priming.
