1·In this study, the morphological characters of chimeras of tuber mustard and red cabbage were described, the acid phosphatase isozyme banding patterns and the molecular marker were analyzed.
本试验以人工合成的榨菜和紫甘蓝离体嫁接嵌合体为试验材料，对其植株形态，酸性磷酸酯酶同工酶及分子标记等进行了研究。
2·Chromosome count showed that the plants, containing non tetraploid cells besides amphidiploid, were chimeras.
染色体检查发现，除了四倍体之外，还存在其它倍性的细胞，呈嵌合体状态。
3·Objective To investigate the effects of developmental stages of tetraploid embryos on mouse chimeras from embryonic stem cells (ES).
目的 探讨四倍体胚胎发育阶段对胚胎干细胞（ES）嵌合体小鼠制备的影响。
