Abstract: The diploid and tetraploid of non-heading Chinese cabbage‘Duanbaigeng’, were used in this research. The diurnal change of Pn with single peak pattern in tetraploid was similar to diploid. No significant difference was found in photosynthetic pigment content and chlorophyoll a /b ratio between diploid and tetraploid. Chloroplast size was bigger and grana stack was thicker in tetraploid than that in diploid.

Key words: Non-heading Chinese cabbage, Ploidy, Diploid, Tetraploid, Photosynthetic characteristics, Chloroplast
