Applications of nitric oxide (NO) for postharvest control.

Endogenously-produced nitric oxide (NO) gas appears to be a natural plant growth regulator in a wide variety of both climacteric and non-climacteric fruits, flowers, vegetables and legume sprout species. Monitoring of vegetative and generative plant organs reveal that temporal progress of maturation and senescence goes hand in hand with a significant decrease of NO emission. Conversely, exogenous application of the gas either by direct fumigation in an O2-free atmosphere or by means of NO-releasing chemicals, markedly delays senescence and maturation of freshly cut or picked produce. Regarded together, experimental data lend support to the possible role of an endogenous concentration-related content of NO as a senescence-delaying plant growth regulator acting primarily, but not solely, by limiting ethylene emission. Control of cyclic nucleotide levels, as in the case of Viagra, may be a further facet of NO involvement in postharvest processes.
