Figure 3.

Photosythetic capacity of coffee plants sprayed with Calonectria hemileiae or fungicide mixture was not affected when plants were inoculated with Hemileia vastatrix.

Maximal photosystem II quantum yield (F_v/F_m) determined on leaves of coffee plants at 20, 28, 36, 42, and 50 days after inoculation with H. vastatrix. The treatments used were plants sprayed with C. hemileiae before at 72 h (Ch/72Hv) and simultaneously with H. vastatrix (Ch/Hv). The Ch and Hv treatments were considered as controls for antagonist and pathogen, respectively. Trifloxystrobin + tebuconazol was used as the fungicide treatment. Plants sprayed with sterile distilled water served as the control treatment. The color bar represents the scale from near zero (dark orange) to near one (dark violet).
