highly significantP values <2.0E−06
Analysis of data from field Summer 2018 and greenhouse Spring 2019 showed very highly significant correlations (all P values <2.0E−06) between the two conditions for all four traits (cuticle thickness—r = 0.99; intercalation depth r = 0.96; diameter of lipid droplets r = 0.84; epidermal cell height r = 0.86) ( Supplementary Table 6 ).
