2011), we counted the number of mature spores in four sporangia of different sporophytes
in order to detect a deviation from the normal production.
They also found forest age positively correlated with sporophyte
numbers and negatively correlated to the percentage of non-expressed shoots.
Experimental studies on megaspore viability, partenogenesis and sporophyte
formation in Marsilea, Pilularia and Regnellidium.
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.
During the 14-day experiment, we monitored a total of 60 amphipods that were distributed over 12 containers, each with one sporophyte
of Macrocystis pyrifera.
These authors reported that after harvesting of Laminaria hyperborea by trawling, though the young kelps grew up rapidly to replace the mature sporophytes
, the epiphytes and holdfast fauna populations took significantly longer to recover.
generation produces spores, each of which develops into a gametophyte, which produces gametes.
morphology of Asplenium dareoides was reviewed, and development and morphology of its gamethophytes were studied for the first time from spore culture on mineral agar.
is found in abundance with foot, seta and capsule.
The fern sporophyte
, as the homologon of the sporogonium in the life-type, is a rooted shoot, i.
SPME/GC-MS analyses demonstrated that capsules emit the majority of sporophyte
However, spatial and temporal patterns of thallus morphology and sporophyte
reproduction have not been investigated in Southern California.
