Problems in post-harvest operations in yam beans, Pachyrhizus erosus (L.) Urban, in the central zone of Mexico.

In the Bajio region of Mexico, conventional postharvest handling of P. erosus roots in sacks of 50-60 kg causes high levels of mechanical injury. Conventional handling resulted in rates of weight loss three times those of roots handled carefully in plastic crates of 22-25 kg. Storing at 13 deg C and 20 deg C and high humidity (in polyethylene bags) was evaluated as a way to reheal the wounds caused by mechanical abrasion. High humidity storage at 20 deg C for seven days permitted an adequate development of wound periderm in the damaged areas. Microscopic observations indicated that the meristematic zone of the root generated new lignified periderm. Storage of roots at 10 deg C caused chilling injury (decay and internal discoloration) after one week whereas storage at 13 deg C reduced weight loss and maintained the quality of the roots during a three-week storage period.
