Resumo
The desert rose (Adenium obesum Balf.) Isa herbaceous, succulent plant family
Apocynaceae, is the center of origin South Africa and the Arabian Peninsula.
Morphological features a thickening of the neck and root system, adaptation is
connected to the storage of water and nutrients, which ensures their survival in arid
locations. In Brazil, the recently pink-the-desert has been demanded by growers and
landscapers due to its high ornamental value, however, there is no technical and
agronomic information that could support a commercial production system. In this
sense, to assess the influence of temperature, humidity on germination, seedling vigor
and substrates in the development of seedlings in pots. Tests were conducted in the
laboratory and greenhouse. We assessed germination rate, germination speed index
(GSI), seedling vigor and substrates for seedling development. There was no significant
interaction between the two factors (temperature x humidity). The temperature 25°C,
germination was more efficient, providing higher germination rate (85%) and higher GSI
(3.55). Germination was not influenced by increased humidity, though the IVG and vigor
of seedlings evaluated increased significantly. Substrates that best contributed to the
development of the seedlings were related to treatment 3 (50% sand + 25% + 25%
commercial soil substrate + fertilizer) and 6 (50% virgen forest soil + 50% commercial
substrate + fertilizer).
