highly significantP = 0.000
A highly significant positive correlation of time until flowering and altitude of origin was observed for the outdoor-grown diploid plants ( R 2 = 0.505, P = 0.000) as well as a significant positive correlation for the other diploid study groups (cold treatment, R 2 = 0.240, P = 0.024; warm treatment, R 2 = 0.260, P = 0.026).
