Changes in the Ripening Process of Avocado Fruit Infected by Fusarium solani. Giora Zauberman, Plant Physiologist, Agricultural Research Organization, The Volcani Center, Bet Dagan, Israel; Mina Schiffmann-Nadel, Associate Professor in Plant Pathology, The Volcani Center, Agricultural Research Organization, Bet Dagan and Faculty of Agriculture, Hebrew University, Rehovot, Israel. Phytopathology 64:188-190. Accepted for publication 6 August 1973. DOI: 10.1094/Phyto-64-188.

Infection of avocado fruit by Fusarium solani caused an accelerated softening when compared with uninfected fruit. The basic physiological processes related to ripening were found to be similar in infected and uninfected fruit; however, an increase in respiration rate, ethylene evolution, activity of pectolytic enzymes, and changes in pectic substances accompanying fruit softening, occurred earlier in the infected fruit. Apparently F. solani causes earlier ripening and softening processes in avocado.
