Chayote fruit quality deteriorates with storage. During storage at 25 deg C, fruits lost 1.3% of their FW per day, compared with 0.5%/day at 15 deg and 0.02%/day at 10 deg . During 5 weeks of storage, unwrapped fruits lost >40% of their FW at 25 deg , 18.9% at 15 deg and 13.0% at 10 deg . The shrivelled appearance due to weight loss detracted from the utility, appeal and saleability of the fruits. Wrapping the fruits in a commercial grade polyvinyl chloride (PVC) film significantly reduced weight loss. Weight loss for the 5-week storage period in PVC-wrapped fruits was 8.3% at 25 deg , 4.0% at 15 deg and 1.3% at 10 deg . Firmness of the skin (exocarp) and flesh (mesocarp) of the fruit remained relatively unaffected by storage at 10-25 deg . The average skin firmness of an edible chayote fruit was 22.1 plus or minus 2.7 N and the flesh 14.3 plus or minus 0.8 N. The firmness of the seed cotyledons within the fruit increased significantly with increasing duration of storage at 25 deg , but not at 1
5 or 10 deg . The increased cotyledon firmness was associated with enhanced sprouting at 25 deg .
