1997	Postharvest Quality Changes of Green Beans Slides Slide 1. Shows the translucent darkened areas on the beans cv.  Jade obtained at Sunnyside Packing on May 27. Beans were held 2 days at 7.5°C (45°F) before the photo was taken. Slide 2. Typical injury symptoms on beans cv. Jade after rough handling (finger pressure to bruise and scraping against wood and plastic). Photos were taken immediately after injury. Slide 3. Examples of beans with injuries as removed from the box brought back to the Mann lab.  Beans were held 2 days at 7.5° C (45° F) before the photo was taken. Slide 4. Three maturities of green beans: Slightly immature, mature and over mature. The slightly immature and mature can be marketed; the over mature beans should not be marketed. Slide 5. Visualization of shrivel symptoms on green beans: no shrivel, slight shrivel and moderate shrivel (top). Moderate shrivel receives a score of 3 on the 1 to 5 rating scale. Slide 6. Typical chilling injury symptoms on green beans (cv. Xera) stored at 0°C (32°F). A general darkening of the beans if the most common symptom. Photo was taken immediately after removal from storage. Slide 7. Typical chilling injury symptoms on green beans (cv. Xera) stored at 5°C (41°F). Rusty brown discolored spots or lesions are the most common symptom. Photo was taken immediately after removal from storage.
