A compilation of the plants mentioned in the sacred book of the Mayans Popol Vuh, recognized as the framework of their cosmogony that was written in the K’iche’ area in Guatemala around the year 1550 was made. Thirty-two different species were identified, from 21 plant families, all native to Mesoamerica. The largest number of species was in Fabaceae with four species, Moraceae and Solanaceae with three species each, in addition to Bromeliaceae, Cucurbitaceae, Malvaceae and Poaceae with two species each. The five most important and frequently named species are maize (Zea mays), jícaro (Crescentia cujete), copal (Protium copal), rubber (Castilla elastica) and cocoa (Theobroma cacao). Eleven species were identified, such as pito wood (Erythrina berteroana) and zibak (Cyperus canus), considered of cosmogonic significance and food plants that are integrated into five groups: fruit trees [zapote (Manilkara zapota), nance (Byrsonima crassifolia), jocote (Spondias mombin), anona (Annona reticulata), matasano (Casimiroa edulis)], grains and seeds [maize, beans (Phaseolus lunatus), cocoa, pataxte (Theobroma bicolor)], vegetables [squash (Cucurbita moschata), tomato (Solanum lycopersicum), chilacayote (Cucurbita ficifolia)], flavourings [chili (Capsicum annuum)], and beverages [maguey (Agave americana)]. Seven species were domesticated: maize, squash, chilacayote, tobacco (Nicotiana tabacum), beans, tomato and cocoa and others for medicinal purposes, fuel and instruments. The description of the creation of man asserts the close relationship of the Mayan culture with plant biodiversity; moreover, the famous milpa, a multi-species Mesoamerican agroecosystem is mentioned that was practiced by their gods © 2022.

Brosimum alicastrum is a tree species in Mexico with wide potential for animal and human food, which is distributed naturally with no silvicultural management, so there is little information on the propagation methods of the species. The objective of this work was to analyze the scientific research published on B. alicastrum, through literature review to know the techniques that exist on its propagation. In addition, the quality of the seedling obtained by sexual propagation and asexual methods (cuttings, layers and grafts) was evaluated in the nursery, by means of experimental designs. 550 scientific articles on B. alicastrum were found, the disciplines where they were published were: Ecology (44.18%), Botany (13.27%), Forest Sciences (11.27%, of which 2.54% worked propagation in the nursery), Zoology (11.09%), Agriculture (9.64%), Anthropology (5.45%) and others (5.10%). Regarding the seed propagation method, the best seedling quality was associated with low porosity substrates (bush soil) and containers with large diameters (36 cm). In the case of asexual propagation, with the layering method when peat was used as the substrate 90% survival was obtained, and by lateral grafting technique 75% yield was found. Due to the little research that exists on the propagation of the species, it is recommended that the selection of the propagation technique is based on the purpose of the seedling; if it is required to shorten the seed production cycles of B. alicastrum the asexual techniques grafting and layering can be more efficient. © 2022 Universidad Politecnica Salesiana.
