Several different sporophytes were collected in the following two localities.
Generally, the sequence and timing of sporophyte development for each species was similar for each forest age class so data was pooled for each species and peaks of each phenostage were used to better show the phenological development (Fig.
spinulosa, has been multiplied by two methods: through caulogenesis from leaf primordium explants procured from in vitro-raised sporophyte and direct spore culture ([13]; Figure 2).
The outside of the rhizome mass of the Polytaenium supported gametophytes and young sporophytes of additional plants of Polytaenium, showing that the site was favorable for its growth and establishment.
tea (reported as Ampithoe tea) on a single Pelvetia fastigiata sporophyte. The interactive effect of nest-building and feeding activities by kelp-curler amphipods on particular blade tissues (e.g., meristems and the influence on growth rate) is not yet completely understood.
In the first method the whole 'head' of the kelp sporophyte is cut off between the bulb at the top of the stipe and the primary blade.
Plants have two generations: sporophyte and gametophyte.
Each species identified was described morphologically using the gametophyte characters (leaf arrangement, midrib, base, apex, margin, cells, and shape) and sporophyte characters (size, shape, texture of capsule and seta, number of teeth).
Sporophyte is found in abundance with foot, seta and capsule.
The structure and properties (viscosity, degree of setting) of the carrageenans vary from species to species, and there are even variations between those obtained from the different phases (sporophyte and gametophyte) of a single species.
