Research Progress on Aluminum Toxicity to Plants and Mechanisms of Aluminum Tolerance in Herbaceous

Soil acidification has attracted great attention in the world. Aluminum toxicity is considered to be an important factor limiting plant growth in acidic soil (pH<6.5). We summarized the chemical form of aluminum in soil, aluminum toxicity to plants, research progress on acid and aluminum tolerance of herbaceous plants and aluminum tolerance mechanism of herbaceous plants, so as to provide reference for further research on aluminum tolerance mechanism of various herbaceous plants in the future.
