Rega nas fases iniciais do cultivo da rosa-do-deserto, Adenium obesum (Forssk.) (apocynaceae)

Abstract

The desert rose is an ornamental plant from the Apocynaceae family, which is widely used to decorate indoor and outdoor well-lit environments. Although it is a relatively new ornamental plant on the market, the desert rose is the fifth most sold in Brazil. The Apocynaceae family encompasses approximately 5,100 species and 550 genera, with a cosmopolitan distribution and a variable habit. The genus Adenium is of Asian and African origin and its species are known as desert rose. In addition to being a very beautiful plant with its sculptural and distinct stems, they show flowers with a great diversity of shapes and colors and the choice of the plant due to the high incidence of heat and light made its adaptation successful. in Brazil, but the technological information and also the agronomic information available are insufficient, which makes the commercial production system impossible and, as a result, promotes an increase in its ornamental value and it is also known that the use of a specific substrate with a large capacity Water drainage is very important for the plant's growth, as the plant's roots cannot support water in large proportions and the desert rose was brought to Brazil, causing a huge effect among collectors of this plant due to its beautiful flowers.The ornamental plants segment is defined as the set of commercial and productive activities of plant species cultivated for ornamental purposes. The present work aimed to evaluate the initial development of desert roses during the three months of growth, irrigated with different amounts of water, with the aim of reducing water consumption and preserving natural resources in large-scale commercial production. The experiment was carried out in a completely randomized design, with five treatments: Control, TA 3 mL twice a day, every 48 hours; TB 5 mL daily; TC 10 mL a day, every 72 hours; TD 20 mL a day, every 96 hours.
