Fig. 2From: Nitrogen deficiency impacts on leaf cell and tissue structure with consequences for senescence associated processes in Brassica napus Dry mass per disc (A, B) and water content (C, D) of the oldest leaves of 18-weeks oilseed rape plants of two 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
