Abstract:
Effect of chitosan on mycelial growth and spore germination of Colletotrichum gloeosporioides was investigated on Potato Dextrose Agar (PDA) containing 0, 0.5, 1.0 and 2.0% (w/v) chitosan dissolved in 0.5% (w/v) acetic acid . The results revealed that 1.5 and 2.0% chitosan were the best concentration for inhibiting the mycelial growth and the spore germination while the complete inhibition were found in the medium containing 0.5% acetic acid. Effect of the chitosan coating on artificially inoculated mangoes by making wound and non-wound showed that the best concentration of chitosan to control anthracnose disease was at 0.5 and 1.0%. These concentration could stimulate chitinase and ?-1,3-glucanase activities. Additionally, the chitosan coating on mangoes could delay rippening, color changes of pulp and peel, reduction of respiration rate, ethylene production, weight loss, total titratable acidity, ascorbic acid and total soluble solid in mangoes. However, the chitosan coating could not maintain firmness of the mangoes.
