Abstract

REGO, Suelen Santos; NOGUEIRA, Antonio Carlos; KUNIYOSHI, Yoshiko Saito  and  SANTOS, Álvaro Figueredo Dos. Morphological characterization of the fruit, the seed and seedling development of Blepharocalyx salicifolius (HBK) Berg. and Myrceugenia gertii Landrum - Myrtaceae. Rev. bras. sementes [online]. 2010, vol.32, n.3, pp. 52-60. ISSN 0101-3122.  http://dx.doi.org/10.1590/S0101-31222010000300006.

The objective of this study was to morphologically characterize the fruits, seeds and developing seedlings of Blepharocalyx salicifolius and Myrceugenia gertii. One hundred fruits and seeds were used for the morphological description and to follow seedling development, 100 seeds were placed in a paper towel substrate at a temperature of 25 ºC and 50 seeds in vermiculite. The fruits of B. salicifolius and M. gertii are fleshy and indehiscent and of the bacoideus type. The seeds of B. salicifolius have a spiral shape, are a brown transparent color, have no endosperm and the embryo is of the pimentoid type. The seeds of M. gertii are oval, have a transparent brown color, are laterally compressed with a mucilaginous endosperm and the embryo is of the myrcioid type. The germination of both is epigeous phanerocotyledonal.

Keywords : plant morphology; Myrtaceae; seed forest.
