在这里报道的实验中，我们监测的第一节间的光生长的芥菜幼苗在黑暗中脉冲后，提供不同的PFR/P. PFR/P和PAR水平的植物生长之间的相互作用的延伸生长，也进行了研究，因为后者以前已被证明修改的程度上的几个响应结束一天的脉冲。最后，我们比较了在相同的黑暗时间段内，在连续WL结束时Pfr/P降低与在连续WL期间或WL向黑暗过渡后几小时类似降低的功效
In the experiments reported here we monitored the extension growth of the first internode of light-grown mustard seedlings in darkness after pulses which provided different Pfr/p. The interactions between Pfr/P and the PAR levels at which the plants were grown, was also investigated as the latter had previously been shown to modify the extent of several responses to end-of-day pulses. Finally, we compared, over the same period of darkness, the efficacy of a reduction in Pfr/P at the end of continuous WL with that of similar reduction during continuous WL or several hours after the WL to dark transition
