Fig. 4.

Germination response of four different collections of Brassica tournefortii seeds following collection from original source sites in 2009. Seeds were tested in 12-h alternating light or constant darkness, with or without 1 µm KAR₁, under eight temperature regimes. Germination was scored 3 weeks after sowing. Bars indicate mean ± 95 % confidence interval for binomial estimates; n = 150 seeds per treatment.
