Fig. 6From: Nitrogen deficiency impacts on leaf cell and tissue structure with consequences for senescence associated processes in Brassica napus Vacuolar volume distribution (a, c, e, and g) and transverse relaxation time distribution (b, d, f, h) of two old leaves of an Aviso plant in control (a–d) and N deficiency conditions (e–h). a and b correspond to rank 0, c and d to rank −2, e and f to rank 0 (in stressed condition) and g and h to rank −1 (in stressed condition). In the vacuolar volume distributions white bar corresponds to spongy vacuoles and hatched bar to palisade vacuolesBack to article page
