In young gametophytes (= sporelings) of the common male fern (Dryopteris filix-mas) short wavelength light (= blue light) specifically increases DNA replication and mitotic activity even if the sporelings have the same growth rate under blue and red light, as determined by dry matter increase. Cell number and DNA content of sporelings of the same age and the same dry matter content are much higher under blue than under red light (Figs. 1, 2). In the second part of the paper it is pointed out that the "cell" (or unit of DNA) may not be used as a system of reference for biochemical data such as protein or RNA content in the case of the fern sporelings (and possibly not in many other organisms either). The appropriate system of reference seems to be the entire multicellular system if precaution is taken that the systems grow with the same growth rate under the different experimental conditions (e.g. under blue and red light in the case of the fern sporelings).
在雄性绵马鳞毛蕨（Dryopteris filix-mas）的幼配子体（即幼苗）中，短波长光（即蓝光）能特异性地增强DNA复制和有丝分裂活性，即便幼苗在蓝光和红光下具有相同的生长速率（以干物质增加量来衡量）。相同年龄且干物质含量相同的幼苗，其细胞数量和DNA含量在蓝光下比在红光下要高得多（图1、图2）。在论文的第二部分指出，对于蕨类植物幼苗（可能许多其他生物体也如此），在诸如蛋白质或RNA含量等生化数据的情况下，“细胞”（或DNA单位）可能不能用作参考体系。如果采取预防措施，确保这些体系在不同实验条件下（例如蕨类植物幼苗在蓝光和红光下）以相同的生长速率生长，那么合适的参考体系似乎是整个多细胞体系。
