Wound‐healing in carrot roots in relation to infection by Mycocentrospora acerina

Abstract

SUMMARYA period at 25 °C or 15 °C in a humidity approaching saturation before storage at 2 °C accelerated wound repair, diminishing subsequent infection by Mycocentrospora acerina in proportion to the period of treatment up to 48 h. The total number of localised lesions was reduced as well as the proportion which subsequently became progressive. Healing involved the accumulation of antifungal substances on the wound surface; patches of oily conglomerates were fungicidal and the remainder of the surface was strongly fungistatic. Only a small proportion of the chlamydospores germinated after wounds had been healed for 48 h.
