Development up to flowering in opium poppy (Papaver somniferumL.) has been divided into four phases from emergence to anthesis which mark changes in its sensitivity to photoperiod: a photoperiod-insensitive juvenile phase (JP), a photoperiod-sensitive inductive phase (PSP), a photoperiod-sensitive post-inductive phase (PSPP) and a photoperiod-insensitive post-inductive phase (PIPP). To predict flowering time under field conditions, it is essential to know how these phases are affected by temperature. Plants were grown in artificially-lit growth chambers and received three different temperature treatments: 15/10, 20/15 and 25/20 °C in a 12 h thermoperiod. Plants were transferred within each temperature regime from a non-inductive 9 h to an inductive 16 h photoperiod orvice versaat 1–4 d intervals to determine the durations of the four phases. Temperature did not affect the duration of the first two phases (i.e. JP lasted 3–4 d and PSP required 4–5 d). The most significant effect of temperature was on the duration of PSPP which was 28, 20 and 17 d at 15/10, 20/15 and 25/20 °C, respectively. The temperature effect on PIPP was small (maximum difference of 3 d between treatments) and the data too variable to indicate a significant trend. Our results indicate that PSPP is the only phase that clearly exhibits sensitivity to temperature.
