Abstract: Magnesium (Mg) is not only the central atom of chloroplast, but also participates in the biosynthesis of quality-related components (theanine) in tea plant. The impacts of Mg on tea quality and plant growth have been well established. However, Mg fertilizer is still not widely used in tea gardens of China, although Mg deficiency frequently occurs. This paper reviewed main studies of Mg nutrition in tea plant in the past 30 years, including the application of Mg nutrition in tea gardens, impact of Mg on tea quality, and interactions of Mg and other nutrients. In view of the shortage of Mg in tea garden soil, insufficient input of Mg fertilizer and unclear mechanism of Mg utilization in tea plant, prospect of research on Mg in the future were put forward.

Key words: tea plant, magnesium, nutrition, tea quality
