Fig. 4. Sensitivity analysis showing variation in simulated days to flower in relation to mean temperature for (A) a photoperiod-sensitive but temperature-insensitive genotype (Ppd Ppd Hr Hr Tip Tip) grown at four latitudes; (B) a photoperiod- and temperature-sensitive genotype (Ppd Ppd Hr Hr tip tip) grown at four latitudes; and (C) photoperiod- and temperature-sensitive (Ppd Ppd Hr Hr tip tip), photoperiod-sensitive but temperature-insensitive (Ppd Ppd Hr Hr Tip Tip), or day-neutral genotypes (ppd ppd -- --) grown at 0° latitude (short day) or 45° north latitude (long day) environment (not all combinations are shown).
