Analysis of tapetum development in the sterile line ‘Bcajh97-01A’ (A line) and the fertile line ‘Bcajh97-01B’ (B line) of Brassica rapa through semi-thin section and transmission electron microscopy observation. Stage 4, mother cell at pachytene/diplotene stage. Stage 5, mother cell at meiosis telophase I. Stage 6, tetrad stage. Stage 7, early uninucleate microspore stage. Stage 8, middle uninucleate stage. Stage 9, late uninucleate stage. Stage 10, early binucleate stage. Stage 11, middle binucleate stage. Stage 12, late binucleate stage. Scale bars in semi-thin sections of anthers: 50 μm. Scale bars in transmission electron microscopy observation: 4 μm
