Fenologia reprodutiva de quatro espécies de Sapotaceae na restinga de Maricá, RJ

Abstract

The purpose of this work was to record the occurrence of phenological events related to the flowering and fructification of Pouteria venosa (Mart.) Baheni, P. psammophila (Mart.) Radlk., Manilkara subsericea (Mart.) Dubar e Sideroxylon obtusifolium (Roem. & Schult.) T. D. Penn. at the Maricá-RJ sand bar in the years of 2003 to 2005. Pouteria venosa produced flowers from May to October, whereas M. subsericea flowered from May to September, and S. obtusifolium produced flowers from August to November. During the period of studies P. psammophila did not flower. The fruits are berry-type, and display synchronism in the maturing and release of their seeds in the months of February and March. Flowering and fructification for the three species is annual, with a negative and significant correlation only between flowering and temperature. For S. obtusifolium correlation was positively significant between fruit development and the abiotic factors of temperature and precipitation.
