RESUMO -Os objetivos do trabalho foram quantificar o rendimento de polpa e avaliar caracteres morfofisiológicos de frutos e sementes de pitangueira-do-cerrado em diferentes colorações, de acordo com o estádio de maturação. Em novembro de 2006, frutos nas colorações verde, laranja, vermelho-clara e vermelho-escura, 50 de cada coloração, foram coletados de 20 matrizes na Reserva Ecológica do Clube Caça e Pesca Itororó no município de Uberlândia. Tais frutos e sementes extraídas dos mesmos foram medidos quanto ao comprimento e largura, além das massas das matérias fresca e seca da polpa. Em novembro de 2007, de 20 matrizes, determinou-se o rendimento de polpa. A distribuição t de "Student" foi utilizada para construir intervalos de confiança para comprimento, largura e massa das matérias fresca e seca de polpa, além de distribuições de frequência percentual para largura e comprimento de frutos e sementes. Grandes amplitudes foram observadas na morfometria dos frutos (8-20 mm de largura; 10-30 mm de comprimento) e das sementes (8-14 mm largura; 7-14 mm comprimento) da espécie, mesmo dentro do mesmo estádio de maturação. O rendimento de polpa foi de 59,1%, quando os frutos foram colhidos com coloração entre laranja e vermelho-clara.

PULP YIELD AND MORPHOMETRIC CHARACTERS OF FRUIT AND SEED OF Eugenia calycinaABSTRACT -The objectives of the study were to quantify the yield of pulp and evaluate morpho-physiological characters of fruits and seeds of the Eugenia calycina in different colors according to the maturation stage. In November 2006, 50 fruits of each coloration: green, orange, bright-red and dark-red, were collected from 20 matrixes in the Ecological Reserve of the Itororó Fishing and Hunting Club in Uberlandia. Fruits and seeds extracted from them were measured for length and width, and the masses of fresh and dry matter of the pulp. In November 2007, pulp yield from 20 matrixes were determined. The distribution t for "Student" was used to build confidential intervals for length, width and masses of fresh and dry matter of the pulp, besides frequency distributions for length e width for fruits and seeds. Great ranges were observed in fruit morphometry (8-20 mm width; 10-30 mm length) and seeds (8-14 mm width; 7-14 mm length), even within the same maturation stage. The yield of pulp was 59.1%, when the fruits were harvested between orange and bright-red colorations.
RESUMOO objetivo do trabalho foi avaliar a influência da coloração dos frutos na emergência e no crescimento das plantas de Eugenia calycina Cambess (pitangueira-do-cerrado), assim como de substratos com diferentes proporções de material orgânico e estruturante. Palavras-chave: maturação do fruto, fruteiras nativas, pitangueira-do-cerrado, sementes. Fruit Coloring and Substrate in Emergence and Growth of Eugenia calycina Cambess Seedlings ABSTRACTThis study aimed to evaluate the influence of fruit coloring in emergence process and growth of Eugenia calycina Cambess seedlings, as well substrates with different proportions of organic and structuring material. Three experiments were conducted: the first of emergence; the second of plant growth, both with fruits of green color, orange/red, light red and dark red; and the third experiment was conducted to compare five mixture of Bioplant supplemented with Vermiculita and coconut i powder n the seedling growth, both in proportion of 20 and 40%. The fruit coloring did not influence the capacity of emergence, time (initial, mean and final), rate and synchrony of emergence of E. calycina seedlings. The growth of E. calycina seedlings is independent of fruit color up to 270 days. The Vermiculita and -coconut powder supplemented by Bioplant do not improved the plants growth up to 120 days of cultivation.
