How is the preservation and anti-corrosion of Chinese roses done
Chinese roses are rich in nutrients and have unique functions. They contain plant-based albumin and anthocyanins rarely found in other plants, as well as abundant vitamins and water-soluble dietary fiber. How is the preservation and anti-corrosion of Chinese roses done? Let's learn about it together with Xiesha Bridge Chinese roses.
The harvesting time of Chinese roses and whether to use plant growth regulators and food atmosphere-modified packaging (gas replacement packaging) greatly affect the quality and storage period of Chinese roses. For long-term storage of Chinese roses, the use of growth regulators such as ethephon for ripening is prohibited. For Chinese roses that need to be transported long distances, pre-cooling should be performed before transportation, and proper temperature and humidity should be maintained during transportation. Attention should be paid to preventing freezing, rain soaking, sun exposure, and ventilation for heat dissipation.
According to Paull R E's manual on rose storage, the best storage temperature is between 6-10°C, with a storage life of about 14 days.
For diseases such as brick-red Fusarium, black Aspergillus, and yellow Aspergillus during post-harvest storage, a mixture of benomyl and copper chlorite, two fungicides, can be used for treatment.
Marisa W et al. (2008) used X-ray irradiation to treat three varieties of Chinese roses with doses of 0, 200, 400, 600, and 800 Gy, and stored them at 10°C for 12 days. The results showed that the soluble solids content, titratable acidity, and fruit sugar concentration of Xiesha Bridge Chinese rose flesh were not affected by irradiation, but the concentrations of glucose, sucrose, and total sugar decreased linearly with the irradiation dose. The degree of softening of the fruit flesh was minimal after treatment with 400 and 600 Gy. The incidence rate was not affected by irradiation, and doses below 800 Gy had no effect on the sensory quality and quarantine safety of Chinese roses.
Chinese roses are one of the hosts for fruit flies, so they need to be treated with insecticides for export. Hoa T T et al. (2006) conducted a study on the hot air treatment of Chinese roses. In order to meet the biosecurity requirements of fruit importing countries, fruits exported from Vietnam's Binh Thuan must undergo hot treatment and then be sealed in polypropylene bags and stored at 5°C for 2-4 weeks. The high-temperature short-time heat treatment requires the core temperature of the fruit to reach 46.5°C for 20 or 40 minutes, or 50, 70, or 90 minutes at 48.5°C. The experiment showed that "Binh Thuan" Chinese roses could only withstand 20 minutes of heat treatment at 46.5°C, with no significant difference in fruit quality after treatment. Whether heat-treated or not, the shelf life of Chinese roses is only 4 days, and if no fungicides are sprayed, decay caused by the T-J disease will occur rapidly at 20°C.
So far, the effective and economical method for long-term storage is still cold storage. There is little reported use of other commonly used methods such as atmosphere modification, ethylene inhibitors, etc., and the application of Xiesha Bridge Chinese roses is not widespread. Especially in tropical hot weather, without combined cold storage, other treatments cannot maintain long-term storage.
The above content introduces the full text of how the preservation and anti-corrosion of Chinese roses is done, hoping it can help you. Also, I hope everyone will come to see more green plant and flower knowledge!
