The COVID-19 pandemic has brought drastic routine changes to the world’s population. Social isolation, one of the recommended practices to curb the spread of the disease, can lead to the development of several problems, such as depression, stress, apathy and loneliness. However, practices associated with the cultivation and contemplation of flowers and ornamental plants can be an option to aid in the care for the mental health of the population. It has been proven that hortitherapy helps in the treatment of mental illness, in the recovery of patients. Biophilia incorporated into architectural design and gardening, as a hobby and occupational therapy, can also be used to improve physical and mental health. Activities can be done indoors, outdoors or even virtual, with flowers and plants used as supporting instruments to make the population feel better, including the situation experienced by the period of seclusion.

The use of chemicals in storage solutions has proved beneficial for the postharvest conservation of cut flowers. However, the effect of these solutions on the water relations of some species is still unknown. Therefore, the objective of the present investigation was to evaluate the water relations in calla lily flowers harvested at different stages and maintained under postharvest solutions with different chemicals. The flower stems were harvested in two stages of spathe opening: the early stage (cartridge) and the 1/3 flower opening stage. The flower stems were dipped in solutions with water (control), 100 mg L-1 sodium hypochlorite (NaClO), 100 mg L-1 aluminum sulfate [Al2(SO4)3], 200 mg L-1 8-hydroxyquinoline (8-HQ) and 10 mg L-1 silver nitrate (AgNO3). Over 9 days, the floral stems were kept in a room at 21 ± 2 °C and 75% ± 5% relative humidity and evaluated for changes in the pH of the solution and the water absorption, transpiration and commercial quality of the cut flowers. The addition of conservation substances to the storage solution induced spathe opening at both harvest stages and promoted water absorption by the stems, thus increasing the efficiency of flower hydration. The water balance maintenance was best for stems stored in water and storage solutions with Al2(SO4)3.

Due to the importance of the flower and ornamental plants sector in Brazilian agribusiness, studies that analyze the situation of its different segments can help to understand and establish policies and actions that support and stimulate their development. The objective was to analyze the profile and behavior of consumers in the productive chain of flowers and ornamental plants. For this, a questionnaire with direct questions was prepared and directed to consumers of flowers and ornamental plants. The application was made personally with direct approaches in places of great movement and specialized technological fairs, and also online through social media, using Google platform. The results were analyzed by comparing qualitative variables using the Chi-Square test. It was identified that the profile of consumers is concentrated in women who live in large cities, consuming an average of R$ 100.00 to R$ 200.00 over a period of one year.
