The methods used to isolate the fungi may be carefully chosen to allow the obtaintion of a representative mycota. The presence of typical terrestrial fungi belonging to Deuteromycotina, seems to be connected with the initial stages of the decomposition of the leaves, whereas the presence of species of Zygomycotina may be expected at the end of the alcuornea. A total of 81 taxa distributed in registers were obtained table 1representing respectively: Email alerts New issue alert. Although the aquatic Hyphomycetes, as well as some zoosporic fungi may be considered initial decomposers, with high capacity to degrade cellulose and lignin compounds Willoughbytheir presence in the leaves of A.

General Alcuornea 10 – Silica in Timbers. A quantitative approach was used to examine the role of light and soil water regime on the variations found in anatomical traits of the palisade and spongy parenchyma, outer epidermal cell wall of the abaxial and adaxial surfaces, the triolinervia of sclerenchymatous area in relation to the triplinefvia midrib area and the ratio of palisade to spongy parenchyma for five distinct ecological populations: Folhas de Alchornea triplinervia Spreng.

Alchornea triplinervia Images – Useful Tropical Plants

The fungi were isolated from the dry leaves in July of and in July of to provide knowledge about the composition of the mycota before submergence in the stream, as a startpoint to follow further changes of the successional fungal communities.

Botanical Description It is a dominant tree, it attains heights from 15 to 30 m. Euphorbiaceae under distinct light and soil water regimes G. Abstract Alchornea triplinervia Spreng.

Considering the high diversity of the terrestrial fungi usually found in submerged substrates, the role of “geofungi” and of the zoosporic fungi that do not produce ergosterol in the decomposition of submerged substrates have to be stressed out in further studies.

Gray e Fusarium oxysporum Schlecht emend. Drying is fairly slow.

Scientific Name Alchornea triplinervia Spreng. How to cite this article. In the plant species mentioned above, the mycota present in the leaves before submergence remained in the substrates during a relatively long period of time, four to six months. The distance among the collection points was around 5 m, being three and two points respectively chosen for each site of the stream. Natural Durability This timber is highly susceptible to fungal and insect attacks.

Fungi were isolated by the leaf disks washing technique followed by plating on culture media and also by using baiting techniques using substrates with chitin, keratin and cellulosewhat resulted on fungal registers corresponding to 81 taxa. The timber is light gray to light pinkish brown in color.

TAPIA (Alchornea triplinervia)

Fibers with distinctly bordered pits. Natural Habitat Alchornea triplinervia is found in rain forests from the sea level up until 1, m of altitude, it is also found in the Atlantic rain forest. Casehardening is also reported. M—late secondary montane forest shaded, unflooded ; M2—early secondary montane forest semi-exposed, unflooded ; SI—primary swamp forest semi-exposed, flooded ; S2—secondary swamp forest exposed, flooded ; and D—deforestation area exposed, unflooded.

A brief summary about the sampling and isolation methods is presented: On certain species of Mucor with a key to all accepted species.

Combining culture methods and baiting techniques, it was possible to verify the presence of terrestrial fungi on the decomposition of submerged leaves and the importance of zoosporic fungi in tripoinervia fungal succession.

In the leaves of A.

The ecology of lower freshwater Phycomycetes in the tube experiment at Blehman Tarn. Also in the leaves of Quercus robur the species of Deuteromycotina were predominant Schoenlein-Crusius et al.

The failure of many species to grow on culture media and the necessity to use baiting techniques to detect their presence on the substrates, make the study of the activity of zoosporic fungi very difficult, justifying their absence in the studies mentioned above.
