Generally, there are two types of embryos: the unicellular embryos that are distinguished for being attached to the parental tissue by suspensor-like structures (Simoes, et al., 2010), while multicellular embryos do not have the
suspensor connecting the callus mass and embryos (Quiroz et al., 2006).
En la portada de Corre-Vuela del 27 de abril de 1910 (Figura 6), algunos rasgos caracteristicos del coon rural tales como la nariz ancha, el grosor y color de los labios, ademas de andar descalzos, con ropas remendadas, asi como el uso de sombrero de paja y

On the other hand, at the end of the induction period electron microscopy evidenced the presence of a great number of proembryos in the callus surface, which were formed by a small
suspensor and embryogenic pole that was composed by no more than two cells.
A globular structure with protoderm and a
suspensor was observed, characterizing the first stage of somatic embryo development (Fig.
Suspensor degenerates at the globular embryo stage.
A
suspensor is attached to upper portion of elbow joint to make it jerk-free and incorporate the change in arm length.
According to Maheshwari (1950), supernumerary embryos of sporophytic nature can originate from nucellus or integuments cells, by zygote or pro-embryo cleavage and differentiation of
suspensor cells.
As medias das areas das insercoes dos ramos do ligamento
suspensor do boleto demonstraram diferenca entra as faces dos membros, sendo o ramo medial (1,26 [cm.sup.2]) maior que o lateral (1,16 [cm.sup.2]), mas ambas proximas do padrao de normalidade de 1,2 [cm.sup.2] divulgado por Reef (6).
