Abstract

FELIX, Francival C.; MEDEIROS, Josenilda A. D. de  and  PACHECO, Mauro V.. Morphology of seeds and seedlings of Handroanthus impetiginosus (Mart. ex DC.) Mattos. Rev. de Ciências Agrárias [online]. 2018, vol.41, n.4, pp.161-170. ISSN 0871-018X.  http://dx.doi.org/10.19084/RCA18126.

Morphological studies with seeds and seedlings of forest species are fundamental for the understanding of forest dynamics and interpretation of results of germination tests. Thus, the objective of this work was to describe the morphology of seeds and seedlings of Handroanthus impetiginosus (Bignoniaceae). For this, the biometry and morphological description of seeds with and without wings were made, as well as the morphometry and morphological description of seedlings during the germination process. Seeds of H. impetiginosus differ little from some species of the genus Handroanthus Mattos, but they do differ in the biometric aspects. The morphological characteristics of the seedling of H. impetiginosus allow its distinction of other species of the genus. Seed germination of H. impetiginosus is phytogean foliar epidermis, with the beginning of normal seedling formation on the thirteenth day after sowing.

Keywords : Seed biometry; germination; seedling morphometry; ipê-roxo; seedling.
