From: Constitutive activation of nitrate reductase in tobacco alters flowering time and plant biomass

Above-ground biomass of F1 hybrids between the 35S:S523D-NR lines and late-flowering breeding lines and their parents, grown at Clayton in 2017 and 2018. Means ± standard errors of means with the same letter are not significantly different at a 5% significance level according to REGWQ groupings. Sample sizes per line ranged from 26 to 34 in 2017 and 58 to 64 in 2018.
