摘要: ABSTRACT CHITOSAN ON THE POSTHARVEST CONTROL OF SOFT ROT IN ‘RAMA FORTE’ PERSIMMONThe objective of this research was to evaluate the effect chitosan in addition de-astringency process on control Rhizopus stolonifer ‘Rama Forte’ persimmon and vitro mycelial growth. Persimmon were submitted using CO 2 (70% / 18 h), hermetic chambers. Next, fruit inoculated through subcuticular injections a R. spore suspension (3x10 5 mL -1 ) hours later at 25 °C immersed into (0, 0.5, 1.0, 1.5, 2.0%), for 1 min. Fruit stored 80% RH, checked rot severity incidence soft rot, during 5-days storage. After storage skin color, firmness astringency index evaluated persimmons. In , growth PDA media emended with or citric acid. Chitosan 1.5% reduces does not influence loss, color.
