abstract = {The relationship betweenleaf variation characteristics and leaf structure characteristics of Pteroceltistatarinowii with yellow leaf was explored to provide a theoretical basisfor the breeding of other ornamental plants. In this study, the differences inpigment content, leaf structure, and chloroplast ultrastructure in leaves of Pteroceltistatarinowii mutant with yellow leaf 'Huiguang' and its original species'Lingyansi No. 1’ were studied. The results showed that the chlorophyll in'Huiguang' leaves decreased significantly, and the carotenoids-totalchlorophyll ratio increased greatly. The palisade tissue cells in 'Huiguang'leaves are short, thick, and loosely structured, while the sponge tissue cellsare irregular in shape and loosely arranged. In addition, the chloroplasts of'Huiguang' leaves were irregular in shape and the grana lamellae were looselyarranged, broken, and missing, with more osmiophilic granules and fewer starchgranules. These anomalies in leaf pigment content and chloroplast structureaffect leaf photosynthesis and chlorophyll accumulation, thereby affecting leaf color changes.},
