Abstract: (140 Views)
In cut rose flowers, petals senescence not only confines the ornamental value but also imposes a significant economic loss. Therefore, delaying the senescence of cut rose flower petals senescence is very significant to acquire high commercial benefit. In this regard, research was conducted to investigate the effect of the application of the new technology of enrichment with oxygen nanobubbles and silicon nano chelate in the conditions of soilless cultivation on the physiological indicators, the stomatal condition, and the vase life of cut roses. The current research is a factorial split-plot experiment in the form of a randomized complete block design with three factors, including two cut rose cultivars (Samurai and Jumilia), nutrient solution enrichment with oxygen nanobubbles (with oxygen nanobubble concentrations of 0 and 20 mg/liter and for 4 minutes per hour), and foliar spraying of 2% silicon nanochelate (with a concentration of 0 and 2 ml L-1 and an interval of 10 days) with three repetitions. Application of silicon nanochelate compared to the control treatment resulted in 13.4%, 15.6%, 25.6%, 18.3% and 28.3% improvement in leaf area, chlorophyll a, chlorophyll b, total chlorophyll and carotenoid content, respectively. Interaction of oxygen nanobubble and silicon nanochelate content of chlorophyll a (14.7%), chlorophyll b (26.1%), total chlorophyll (18%), carotenoids (27.2%), stomatal area (7.41%), and diameter increased stomata (4.48%), stomata length (7.30%), stomata width (6.49%), and the ratio of the number of open to closed stomata (53%) compared to the control. The use of oxygen nanobubbles had a more pronounced effect compared to silicon nanochelate, which can be introduced as an indicator treatment for increasing the post-harvest life and quality of rose-cut flowers.
