The study investigated the possible role of the three classes of constitutive antifungal substances in mangoes in the differential cultivar resistance to anthracnose and stem-end rot (SER). Fruits of eleven mango cultivars were screened for anthracnose and SER development during ripening. Basal level of antifungal activity due to constitutive gallotannins,(More)
Unripe mangoes contain a network of minute latex canals in its exocarp, outer mesocarp and the pedicel. Latex, when retrieved, separates into an upper oily layer containing antifungal resorcinols and a lower aqueous layer with chitinase activity. Latex disappears in coincidence with ripening and decline of fruit resistance to fungal pathogens. The present(More)
