摘      要：The relationship between leaf variation characteristics and leaf structure characteristics of Pteroceltis tatarinowii with yellow leaf was explored to provide a theoretical basis for the breeding of other ornamental plants. In this study, the differences in pigment content, leaf structure, and chloroplast ultrastructure in leaves of Pteroceltis tatarinowii 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-total chlorophyll ratio increased greatly. The palisade tissue cells in Huiguang leaves are short, thick, and loosely structured, while the sponge tissue cells are irregular in shape and loosely arranged. In addition, the chloroplasts of Huiguang leaves were irregular in shape and the grana lamellae were loosely arranged, broken, and missing, with more osmiophilic granules and fewer starch granules. These anomalies in leaf pigment content and chloroplast structure affect leaf photosynthesis and chlorophyll accumulation, thereby affecting leaf color changes. © 2022 Yongchang Yu, Chen Lv, Min Liu and Tiantian Chen.
