Mechanical stress caused by wind on leaves of Theobroma cacao: Photosynthetic, molecular, antioxidative and ultrastructural responses
Fig 11
Activity of ascorbate peroxidase (APX) on leaves of CCN 51 cloned plants of T. cacao exposed to different wind speeds (2.5, 3.5 and 4.5 m s-1) and exposure times (0, 3, 6 and 12 h).
Mature and young leaves exposed to intermittent wind (A and B), respectively. Mature and young leaves exposed to constant wind (C and D), respectively. Averages between exposure times and between speeds followed by the same uppercase and lowercase letters, respectively, do not differ by Scott-Knott test (p<0.05). Mean values of four replicates (± SE).
