Thermal characteristics of seeds of wild herbaceous (91 species) and crop plants (34 species) pooled across taxa significantly differed in the width of their thermal windows W T (wild herbaceous plants 22.6 ± 0.42°C, crop plants 24.8 ± 0.61°C, p MW < 0.001), which are associated with differences in their minimum germination temperatures t d min (3.0 ± 0.31°C, 1.6 ± 0.45°C, p MW < 0.05) and marginally significant differences in the “skewness” of their Lactin functions (71.4 ± 0.87%, 74.4 ± 1.15%, p MW = 0.052).
