Although tubular forms are the most common, other morphological varieties are also known: prismatic, rolled, pseudospherical, and platy forms.
A great number of intraspecific morphological varieties are known for laminarialean algae (review in [ 14]).
The maximal number and the greatest morphological variety were detected at horizons with the depth of 3534, 3555 and 3595 m.
The morphological variety was shown not only to occur within reasonable cure cycle variations for neat resin, but were also induced through a processing change in a graphite-reinforced composite containing this resin.
In Austria, the purity of oilseed rape varieties is not controlled on a genetic basis but only by checking morphological characteristics [ 21].
Due to genetic diversity, the morphological difference between natural varieties are typically greater than that of transgenesis, as we saw in our comparison between MH86 vs. D62B and DXT vs. D62B.
For instance, in the past, based on morphological and physiological traits, two botanical varieties were classified under the subspecies fastigiata (that includes other varieties fastigiata and vulgaris) while AFLP markers suggested relationships of aequatoriana and peruviana to hypogaea rather than subspecies fastigiata [ 45].
The two varieties are distinct in many morphological traits, including plant height, growth habit, capsule shape, leaf shape and color, as well as resistances to multiple diseases.
Indeed, our morphological and genetic data suggest that names of some varieties are interchangeable (Table 4 and Figure 5), for instance Ifermourgh and Aberyoun in the Atlas Mountains.
In viticulture, grapevine varieties are considered to consist of clones that share common morphological traits.
