Abstract:

The major cause of vase life reduction in cut flowers is water relation interruption which is mostly due to vase solution microbial proliferation and consequently vascular occlusion resulting in solution uptake reduction. In order to control microbial proliferation biocides are usually integrated in vase solution preservatives. Beside microbial proliferation control, biocides could affect cut flower’s quality and physiology in various aspects. In order to found an easy to use, non toxic and inexpensive compound for large scale application, cut ‘Cherry Brandy’ roses were treated with colloids of nano silver particles (1, 2.5 or 5 %) and sterilized distilled water (control). Effects of nano silver as vase solution biocide and its impact on vase life, water relation, vase solution microbial kind and population beside different physiological parameters such as chlorophyll degradation, chlorophyll fluorescence and membrane permeability were investigated during this study. Results indicated that nano silver treatment significantly increased vase life and did not result in any evident side effects. It also improved solution uptake and consequently retarded weight loss. Beside that nano silver application as vase solution efficiently disinfected vase solution and consequently prevented vase solution microbial proliferation. Membrane permeability was best maintained by 1% nano silver treatment. Besides that, 1% nano silver treatment resulted in the highest chlorophyll content. Nano silver application also resulted in chlorophyll fluorescence reduction and loss of photosynthetic activity during vase life.
