Figure 2. Changes in roots morphology and structure of barley under DS.

Figure 2

(A, B) Morphology of roots under CC and DS. (C–E) Microstructure of root transversal section at 10, 20 and 30 DPA under CC. (F–H) Microstructure of root transversal section at 10, 20 and 30 DPA under DS. (I) Area of root vessel transversal section. Error bars on the graphs indicate the standard deviation calculated from three replications. Asterisks above the histograms indicate significant difference between treatments at p < 0.05 as determined by t-test. CC, control condition; Co, cortex; DS, drought stress; RH, root hair; En, endodermis; Ve, vessel. Scale bars: (A, B) 20 mm, (C–H) 100 µm.
