The cut flower industry is expanding world-wide and Australia is actively seeking to generate niche markets for its unique range of native flora. Because Australia is geographically isolated from the high volume markets of Europe and North America, growers are heavily reliant on technologies that maintain the quality of post harvest produce during transportation. Australia must therefore take a leading role in the development and marketing of technologies that provide Australian producers a competitive advantage over their foreign counterparts.

This report details a brief project undertaken to evaluate the use of a soluble nitric oxide donor chemical (DETA/NO) to delay senescence in a range of Australian native cut flowers. The findings indicate that DETA/NO can delay the appearance of senescence features in some flower species. The report also details recommendations for future work to be undertaken to gain a fuller understanding of the results generated by this preliminary study.
