The orchid family (Orchidaceae) is the second largest family of flowering plants, with about 700 genera, some 20,000 species and the more than 100,000 hybrid cultivars distributed nearly worldwide. These are perennial plants that live year after year. From ancient times, orchids have been a symbol of love and beauty, and thanks to the beauty of flowers and possibilities of application, they are very popular in ornamental horticulture. The size of the flower varies from small to large diameters of 20 centimeters. Orchids that grow in soil at ground level can be found in temperate climates, while those that grow in crevices and backwaters are mostly native to tropical or subtropical regions. The range of orchids is large, but some genera can be grown relatively easily. Some of them belong to the genera Cattleya, Cymbidium, Dendrobium and Phalaenopsis. The genus Phalaenopsis gained in popularity at the end of the 20th century, and today it is the most sought-after potted plant in all homes. The natural habitat of this orchid is Southast Asia, parts of India and northern Australia. The flowers can be monochromatic or bicolor that last for a long time in appropriate conditions and most importantly, they bloom every few months. For the purposes of the research, white, yellow, pink orchids and a combination of white and purple colors were used. Orchids were stored in a refrigerator at a temperature of 5°C and 10°C for one to ten days. On the first, fifth and tenth days of storage in refrigerators, samples of petals were taken by which CHNS analysis determined the protein content as an indicator of aging. Upon completion of storage, the flowers were arranged in a total of 6 glass vases; 2 with 500 ml of drinking water, 2 with 500 ml of distilled water and 2 without water. Temperatures and humidity, changes in the mass of flowers and the volume of water in vases, and the general condition of the flowers were monitored daily. Storage of orchid flowers at a temperature of 5°C and 10°C resulted in a change in the flowers in the form of wrinkling, petal damage and loss of strength. The period of storage of flowers in the refrigerator for ten days did not extend the life of flowers placed at room temperature in containers with water and without water.
