Environmental factors affecting vascular streaking, a postharvest physiological disorder of cassava root (Manihot esculenta Crantz).

Waxed cassava cv. Valencia tubers taken from 12-month old plants were stored in a controlled atmosphere at 25 deg C for 3 days. RH was 54-56% (low) or 95-98% (high) and O2 levels were 21% or 1%. Low RH plus an ambient O2 level enhanced vascular streaking (VS) development (46% incidence). Reduction of O2 to 1% at low RH reduced VS development (15% incidence). However, VS was almost completely inhibited (1.4% incidence) at high RH irrespective of the O2 level. It appeared that the occurrence of VS in cassava tubers was primarily related to water stress in the tissue. Oxygen was secondarily involved in the discoloration reaction.
