The algae can be divided into several types based on the morphology of their vegetative, or growing, state.
In our study, the morphology of both vegetative and reproductive organs of B. formosana obtained from cryopreserved seeds was normal with no significant variation observed (Figure 2).
This study improve, an efficient protocol was established that maintained seed viability and enhanced the germination rates of seeds, compared with previously described cryopreservation methods, and the germinated seeds showed normal morphology of both vegetative and reproductive organs.
The morphology of the vegetative structures of A. limonea is distinctly different than A. luteobubalina, and can be used to distinguish the two species.
In summary, the data presented here indicate a high similarity in the morphology and ultrastructure of vegetative cells and cell walls of Interfilum and Klebsormidium, and this similarity is in concordance with results of a recent phylogenetic analysis (Rindi et al., 2011).
Unlike the stunted and deformed vegetative morphology of Li 1 plants [ 5], Li 2 has normal vegetative growth, and the phenotype of the seed cotton is similar to Li 1.
In addition, floral and vegetative morphology of Magnoliidae is highly variable and several of these variable traits have been shown to be associated with variation of diversification rates in other flowering plant lineages [ 10].
Classifying parasitic plants using morphological characters has long been difficult because of the extreme reduction or alteration of vegetative and floral morphology that occurs in holoparasitic lineages [ 3, 14].
Additionally, they present a large diversity of vegetative and floral morphology, exhibiting a great variety of pollination mechanisms, allowing the colonization of different types of environments (Hoehne 1949).
