Relationships between different factors examined in this study.
Solid lines indicate a statistically significant relationship. Dotted lines indicate factors that were conserved in the final selected models, but were not statistically significant. We did not find any significant interaction effects.

Number of days between seed sowing and flowering between the three carrot varieties.
Variety: E = excellent, M = medium, P = poor. Line: male sterile (♀) and male fertile (♂) lines broken out for each variety. Data ceased being collected at 365 days. Boxes represent the middle 50% of the data, lines within boxes are the median.

Coefficients table of GLM for carrot phenology.
Variety: E = excellent, M = medium, P = poor. Line: male sterile (♀) and male fertile (♂). The intercept condition is the male-sterile, excellent line.
Fig 4.
Seed set amongst the three carrot varieties.
E = excellent, M = medium, P = poor. Boxes represent middle 50% of data, lines within boxes are the median.
Fig 5.
Pollen viability amongst the different varieties.
Each sample point represents all male-fertile flowers with pollen at the time of sampling (evenly spread throughout the 7 time and 3 temperature treatment combinations). Viability was calculated as a proportion viable out of 200 grains. E = excellent, M = medium, P = poor. Boxes represent middle 50% of data, lines within boxes are the median.

Log glucose concentration in nectar at different temperatures for the female lines of all three carrot varieties.
E = excellent, M = medium, P = poor.

Concentrations of nectar phenolic compounds by carrot variety.
E = excellent, M = medium, P = poor. Boxes represent middle 50% of data, lines within boxes are the median.
Fig 8.
Concentration of nonanal versus time-of-day.
Values are from six 'medium' plants sampled repeatedly over the course of 24 hours. The red line is the trend line created by the GAMM, the dark grey area is the 95% confidence interval.
