Fungi and cellulolytic activity associated with decomposition of Bauhinia purpurea leaf litter in a polluted and unpolluted Hong Kong waterway. Once again, the dominance of terrestrial fungi on the submerged substrate may justify these results.

Dynamics of the fungal population on leaves in the stream. Botanical Description It is a dominant tree, it attains heights from 15 to 30 m. Gray and Fusarium oxysporum Schlecht emend. The colonies of Deuteromycotina, Zygomycotina and Ascomycotina that grew around the leaf disks were isolated after seven days of incubation o Cwhile the zoosporic fungi were observed after five days of incubation.

Table 1 – Fungal succession on A. Color The sapwood is triplinervua differentiated. It is a dominant tree, it attains heights from 15 to 30 m. Tukey tests were carried out for multiple comparisons, while one-way factor variance analysis was used to test for differences among ecological populations.

Forty litter bags were submerged at each of five collection points along the stream. During the first period of the experiment, the highest number of fungal specimens was registered in January of 38 registers and the lowest in August of 13 registers. Ecology of fungi on plant remains above the soil.


Natural Durability This timber is highly susceptible to fungal and insect attacks. Fibers with distinctly bordered pits. 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 percentage of sclerenchymatous area in relation to the total midrib area and the ratio of palisade to spongy parenchyma for five distinct ecological populations: Although the monthly obtained mycota had been composed by species of different taxonomic groups, the fungal succession was defined by the initial presence of typical terrestrial leaf inhabiting fungi mostly Deuteromycotinafollowed by species of Mastigomycotina and Zygomycotina.

Light accounted for the variations found in palisade and spongy parenchyma while the combination of light and soil water determined the variations found regarding the outer epidermal cell wall of the abaxial surface, the percentage of sclerenchymatous area in relation to the total midrib area and the compaction of the spongy parenchyma.

Developmental evidence helps resolve the evolutionary origins of anther appendages in Globba Zingiberaceae. Isolation of cellulose-decomposing fungi from the soil. On the ecology of heterotrophic micro-organisms in freshwater.

Zoosporic fungi and aquatic Hyphomycetes showed a tendency to occur in an intermediate phases of the succession. Oxford University Press is a department of the University of Oxford.

Drying Defects Ease of Drying: Trichoderma virideFusarium oxysporumPenicillium hirsutumAlternaria alternataMucor hiemalisEpicoccum purpurescens and Aspergillus clavatus were components of the mycota isolated from the leaves prior the submergence until intermediate stages of the decomposition table 1.

However, the fungi present at the beginning of the succession showed higher register numbers than those triplineriva the end of the process table 1. Breakdown and colonization of Nothofagus leaves in a New Zealand stream. Checking, cupping and twisting are reported. Also in the leaves of Quercus robur the species of Deuteromycotina were predominant Schoenlein-Crusius et al.

Fungal succession on leaves of Alchornea triplinervia Spreng. Systematics at different levels. 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.

Atlantic forestintraspecific variationtropical tree.

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 alcbornea of the activity of zoosporic fungi very difficult, justifying their absence alchornwa the studies mentioned above.

This species is dioecious, meaning that it has male and female individuals. Curvularia brachyspora, Fusarium clamydosporum, F. The occurrence of R. These populations developed different response levels to the environmental factors studied, namely light and soil water regime. Fungi were isolated by the leaf disk washing technique Pugh et al.
