Morfologia de fruto, semente e plântula de três espécies de Annona (Annonaceae)

resumo -O araticunzeiro (Annona crassiflora Mart -Annonaceae) é uma frutífera nativa do cerrado brasileiro que necessita de estudos visando à geração de dados para subsidiar pesquisas relativas à sua domesticação. Com o presente trabalho, objetivou-se estudar uma população de araticunzeiro em relação ao diâmetro do caule e altura das plantas, à produção e às características físicas e químicas de frutos. Nas plantas, mensuraram-se diâmetro do caule, altura e produção de frutos. Nos frutos, analisaram-se os diâmetros longitudinal (DL) e transversal (DT), a relação DL/DT, as massas do fruto, da casca, da semente e da polpa, e calculou-se o rendimento de polpa. Na polpa, efetuaram-se as determinações de sólidos solúveis (SS), acidez titulável (AT), relação SS/AT, pH e umidade. As árvores possuem diâmetro do caule de 10,4±3,1 cm e altura de 3,7±0,7m com produção média de 6,0±3,6 frutos por planta. Em média, os frutos possuem DL de 14,2±1,4, DT de 15,2±2,2 e relação DL/DT de 0,9±0,1; possuem massa média de 1.565,5±508,5g, tendo as massas da casca, das sementes e da polpa médias de 662,2±198,2g, 179,8±66,2g e 723,5±276,7g, respectivamente, com rendimento médio de polpa igual a 45,9±4,7% do fruto. Na polpa, constataram-se médias de SS de 17,60±1,86 °Brix, AT de 0,37±0,11% de ácido málico, relação SS/AT de 52,23±17,64, pH de 4,45±0,23 e umidade média igual a 74,3±2,86%. O araticunzeiro possui características físicas e químicas que o tornam uma alternativa para a fruticultura nativa brasileira. termos para indexação: araticum, marolo, polpa, Brix. CHARACTERIZATION OF PLANTS AND FRUITof araticum plant (Annona crassiflora mart.) native to the cerrado of mato Grosso aBstract -The araticunzeiro (Annona crassiflora Mart -Annonaceae) is a native fruit from the Brazilian Cerrado requiring studies to generate data to support research related to its domestication. This research aimed to study a population of araticunzeiro relating to the stem diameter and plant height, production, and physical and physical-chemical characterization of its fruits. Diameter of stem, height, and fruit yield of plants were measured. In the fruits, longitudinal (LD) and transverse (TD) diameters, the LD/TD ratio, the masses of fruit, peel, seed, and pulp were analyzed; and the pulp yield was calculated. In the pulp, determination of soluble solids (SS), titratable acidity (TA), SS/TA ratio, pH, and moisture were performed.

-Araticum (Annona crassiflora Mart. -Annonaceae) is a species with great ecological importance and potential for fruit production. Its fruits, seeds and seedlings were morphologically described in this article as being the main objective of this study. To describe and illustrate the examples, 100 seeds and 42 fruits were analyzed; the latter being collected in Santo Antônio do Leverger -MT -Brazil, in 2011. To describe the morphology of the seedling, 100 seeds were germinated in two different environments. The araticum plant has a compound, multiple strobiliform, globose-subglobose and fleshy fruit, with average measures of 12.9 cm length, 13.5 cm width, 12.7 cm thickness, weight of 1,187.0 g and 99.2 seeds per fruit. The seeds are obovoid, hairless, smooth with a bony aspect and a pale brown color; they have an average of 17. 7 mm length, 10.8 mm width and 8.3 thickness. Epigeous and phanerocotylar germination begins about 148 days after sowing. All morphological data of araticum fruits, seeds and seedlings can be used to recognize the botanical family and, when associated to other features, to recognize the species in the field.
