Abstract
Abstract The temperature effect on the interaction between fungal isolates of papaya was studied. Rhizopus stolonifer, Colletotrichum cobbittiense, Fusarium pernambucarum, and Alternaria arborescens were grown in papaya agar in pairs, one against the other, at 13, 25, and 35 °C. The growth rate for each fungus was compared when grown alone or paired. Four types of interaction were observed: mutual intermingling, mutual antagonism on contact, dominance on contact, and dominance at a distance. At 13 and 35 °C, F. pernambucarum was more competitive whereas at 25 °C R. stolonifer does. In vivo validation showed R. stolonifer was the dominant fungus at 25 °C but coexists with C. cobbittiense forming a second infection. Then, a hierarchy may be established through a growth mechanism to infer which fungi may develop first and damage fruit to prevent postharvest losses. These findings could improve the management of papaya fruit in the postharvest stage. HIGHLIGHTS Several species of fungi are responsible for postharvest diseases in papaya. Diseases development depends on environmental and fruit physiological conditions. One species may dominate or inhibit other’s or can coexist as well. Interactions between pathogenic fungi may be considered to infer fungi development. These results may help us to improve the postharvest treatment of papaya.
期刊介绍:
Archives of Phytopathology and Plant Protection publishes original papers and reviews covering all scientific aspects of modern plant protection. Subjects include phytopathological virology, bacteriology, mycology, herbal studies and applied nematology and entomology as well as strategies and tactics of protecting crop plants and stocks of crop products against diseases. The journal provides a permanent forum for discussion of questions relating to the influence of plant protection measures on soil, water and air quality and on the fauna and flora, as well as to their interdependence in ecosystems of cultivated and neighbouring areas.
