RESUMO:

The Orchidaceae family is one of the largest and most diverse groups of angiosperms, with a wide geographic distribution, high species diversity, and significant ecological, economic, and ornamental importance. In Brazil, orchids represent one of the most significant groups of native flora, contributing to the maintenance of biodiversity and arousing growing interest in scientific studies and conservation actions. Among the genera belonging to the family, Cyrtopodium R. Br. stands out, predominantly neotropical and with a high center of diversity in Brazilian territory, especially in Cerrado areas. The species of this genus have morphological and physiological adaptations that favor their survival in environments subject to water seasonality and specific edaphoclimatic conditions.

In this context, Cyrtopodium cachimboense Van den Berg & Batista stands out for its distribution restricted to the Serra do Cachimbo, a region located between the states of Pará and Mato Grosso. Despite its ornamental potential and relevance to the conservation of Brazilian flora, the species is still poorly studied, especially regarding its cultivation, propagation, and adaptation requirements to different environmental conditions. The lack of information limits the development of efficient protocols for seedling production and ex situ conservation.
The adaptation of the species becomes even more relevant due to the differences between the natural conditions of the Cerrado and environments under Amazonian influence, where many crops are grown. Factors such as humidity, rainfall, and substrate characteristics can directly interfere with seedling establishment. Thus, aspects related to root development, substrate selection, and the use of rooting agents and biostimulants become fundamental to the success of cultivation.

In addition, biotechnological techniques, such as in vitro cultivation, have expanded the possibilities for propagation and conservation of native species. Seedling development depends directly on the nutritional conditions of the culture medium, highlighting the importance of adequate fertilization. In this scenario, pyroligneous liquors emerge as sustainable alternatives with biostimulant potential. Thus, the present study aimed to evaluate the effects of different rooting agents, substrates, and in vitro fertilization strategies on the development and acclimatization of Cyrtopodium cachimboense, contributing to the improvement of cultivation, conservation, and seedling production protocols for this species.
