Total leaf area is reduced under low N and P availability from day 25 after emergence. a General view of plant growth system. b The number of fully expanded green leaves in plants grown in Full, LowP, LowN or LowNP treatments. Data collected every 5 days from 10 days-after-emergence (DAE) until day 40. Points show the coefficient estimated for each treatment, with bars extending +/− 1 standard error (SE). Colored polygons follow SE bars. Significance of treatment effects on a given day (Kruskal-Wallis test; p-value adjusted for multiple tests) are indicated below the x-axis as *** p < 0.001, ** p < 0.01, * p < 0.05, p < 0.1. C-L) Coefficients of fully expanded green leaf area and stem height as B for further non-destructive traits. The arrow in L indicates the point at 25 DAE selected for the harvest of plants grown in the subsequent RNA sequencing experiment
