Nitric oxide (NO) is a highly reactive free radical gas that is an important endogenous regulator in many human physiological systems but it was not until 1996 that plant metabolism of nitric oxide was first demonstrated. A scoping survey has indicated that short term application of nitric oxide gas after harvest can extend the postharvest life of fruit, vegetables and flowers.Data will be presents that optimises the postharvest benefit to the non-climacteric produce, broccoli and mushroom, of fumigation.To overcome the logistical difficulty of fumigation, the use of a water soluble, solid nitric oxide donor compound was found to extend the vase life of a range of flowers with different sensitivity to ethylene.
Initial studies on the potential use of such donor compounds with fruit and vegetables will also be reported.
