Figure 2

The impact of soil drought stress (25% WHC) on the structural features in the flower abscission zone (AZ) of Lupinus luteus. For observations, sections of AZ were excised on the 48th day of cultivation. Samples of AZ from control and drought-stressed plants were stained with toluidine blue (A,B,E,F) or Coomassie Brilliant Blue (C,D,G,H). Images B, D, F, and H are magnifications of different areas presented in A, C, E, G, respectively. AZ area was marked by black dotted circle (A,C,E,G). Abbreviations: PROX—stem fragments below the AZ, DIST—flower pedicel fragments above the AZ. Scale bars: 40 µm.
