卷心菜（cv. Ernando）种子基于它们的叶绿素荧光信号（低、中、高或非常高）被单独地分选成4个子样品。叶绿素荧光信号的大小与种子质量呈负相关，所述种子质量表示为发芽率、正常幼苗的百分比、发芽率（至50%发芽的时间（T50））和发芽均匀度（T75-T25）。通过去除叶绿素荧光信号非常高的种子（13.2%的种子），可以将种子批中正常幼苗的百分比从90%增加到97%。叶绿素荧光技术是一种高灵敏、快速、无损的种子分选方法。
Cabbage (cv. Ernando) seeds were individually sorted into 4 subsamples based on their chlorophyll fluorescence signals (low, medium, high or very high). The magnitude of the chlorophyll fluorescence signal was inversely related to seed quality, expressed as germination percentage, percentage of normal seedlings, germination rate (time to 50% germination (T50)) and uniformity of germination (T75-T25). It was possible to increase the percentage of normal seedlings in a seed lot from 90 to 97% by removing seeds with very high chlorophyll fluorescence signals (13.2% of seeds). The chlorophyll fluorescence technique is a highly sensitive, rapid, non-destructive method for sorting seeds.
