The research and application of DNA barcoding in plant was still in its early exploring stage and inferior to that in animals. Three underlying problems for plant barcoding still persisted. First, there were no good and consistent criteria for the selection and assessment of barcodes. Second, the research of DNA barcoding based on thorough morphological taxonomic revision is necessary, but has been lacking. Third, previous studies in plants were mainly carried out on a large scale, which only few species within one genus and single or few individuals from the same species were sampled, producing superficially higher rate of discrimination and lower credibility of reference database. Until now, rbcL and matK are undoubtedly the most useful barcodes to provide a universal framework for land plants at and above generic levels. However, they do not provide enough informative sites to identify all the species within some genera, in particular those with recent rapid radiation.
在植物类群中条形码的研究和应用尚处于探索阶段，稍落后于动物类群的研究，这主要表现在：1）DNA 条形码的选择及其评价仍没有统一的标准；2）类群较全面的形态分类学修订和植物DNA 条形码研究的结合十分缺乏；3）以往研究在取样上尺度较大，而对具体类群的研究较少，一个科或一个属只用有限的种类作为代表，同一种内的取样个体数量也不足，这样表面上看来利用选定的DNA 条形码可以容易地把代表物种区分开，但实际上目前建议的植物DNA条形码（例如由生命条形码咨询委员会植物工作组最近提出的 rbcL 和 matK）由于其分子进化速率较慢，在种级水平上，特别是对于那些经历了适应辐射或快速进化的属来说，分辨率较低。
