| Soil salinity is a major environmental factor limiting the growth, development, yield and quality of cereal
crops. Rice is most sensitive to high salinity. Thus, improving rice yield under salt-stress is an important issue for national
agricultural workers. This article summarized the damage mechanics of salt-stress in rice, and analyzed the effects of saltstress
on seed germination, seedling growth, tillering period and fruiting period of rice. On this basis, it was also summed
up the main mechanisms of adapting and fighting salt -stress, which included the osmotic regulation, the membrane
protection of scavenging ROS, salt exclusion, ionic compartmentation and the molecular mechanism of salt tolerance.
Finally, some common measures to enhance the rice tolerance on salt injury were listed, to provide theoretical basis for
further research. |
