Given the marked photoperiodic control of the frost-hardening process in woody species at high latitudes, it is understandable that they harden more extensively compared to populations at lower latitudes under similar temperatures.

It's been known for some time that when people are denied photoperiodic cues their rhythms tend to lengthen, usually stabilizing between twenty-seven and thirty-six hours.

The plant is extremely photoperiodic, with most varieties only flowering with day-light less than 14 hours a day.

Its triticale progeny indicated that in the act of fertilization it had created dwarfs, introduced partial photoperiodic insensitivity, and completely overcome the sterility barrier, which had inhibited progress in triticale improvement for decades.

Day-length-the majority of Dioscorea spp. exhibit a photoperiodic response and although day-lengths greater than 12 hours favour the growth of the vine, tuber development is normally most satisfactory under short-day conditions (10-11 hours of daylight).

The difference will be exacerbated because birds, the most well-represented endotherms in the analysis, demonstrate constrained phenological plasticity due to photoperiodic induction of gonad maturation and migration, especially for long-distance migrants.

Now, in the latest study, using specially designed photoperiodic chambers, which allow precise control over light exposure at night, he and his research team have demonstrated that manipulating light intensity at night, and thus melatonin production, dramatically affects human breast cancers growing in rats.
