Fig. 1From: Nitrogen deficiency impacts on leaf cell and tissue structure with consequences for senescence associated processes in Brassica napus Chlorophyll content (A, B) and yield (C, D) of the oldest leaves of 18-weeks old plants of two oilseed rape genotypes, Aviso (A, C) and Express (B, D), grown in two conditions: control (solid line) and nitrogen deficiency (dotted line). Each data point corresponds to the average of four repetitions. Relative leaf rank 0 corresponds to the last leaf appearing before vernalization. Different letters mean significant (p < 0.05) differences between leaf rank of the same condition and stars highlight significant differences between conditions for the same leaf rankBack to article page
