With the continuous expansion of grape planting area, the leaf chlorosis of grape often occurs in China and other grape producing areas in the world, which seriously affects the yield and quality of grape fruits and seriously restricts the development of grape industry. The occurrence of this phenomenon is often affected by many factors. In this paper, the causes of chlorosis are mainly divided into two categories: pathological chlorosis and physiological chlorosis. The pathological chlorosis is mainly induced by phytoplasma and virus disease. The physiological chlorosis is mainly induced by salt stress and alkali stress. The chlorosis of leaves caused by salt stress was mainly due to the reduction of chlorophyll synthesis by the toxic effect of single salts, while the chlorosis caused by alkaline stress was mainly due to the blockage of iron transport in the plant caused by the accumulation of NO₃^- and HCO₃^- induced by alkaline soil conditions. In addition, this paper also summarizes the influence of the grape leaf chlorosis on plants, the prevention and correction techniques, the physiological mechanism of grape resistance to iron deficiency and the screening of varieties resistant to iron deficiency, and briefly summarizes the shortcomings of the current research on the grape leaf chlorosis, in order to provide a theoretical basis for the further research on the grape leaf chlorosis and the prevention and correction of chlorosis in grape production.
