  • Relationship Between Ambient Airborne Fungal Levels and Meteorological Data

    1527 Words  | 7 Pages

    Total Spore Trap Sampling Method The spore trap method is used due to the ability to immediately identify a large spectrum of the majority of fungal spores within the air. This method is able to identify species that are unable to culture well or those that are no longer viable, but present. Alternatively within the industry there is not a consensus on the method. Downfalls include the difficulty of identifying some mold spores and there is no differentiation between non-viable and viable spores

    soil surface (Morton and Hall, 1989). If the weather (moisture and temperature) is favorable, small mushroom-like structures called apothecia will be produced on the sclerotia. Each sclerotia can several apothecia. Apothecia can produce millions of spores called ascospores. Ascospores will be released in air when the apothecia is mature. Some ascospores land on canola plants and infect dead canola tissues like fal... ... middle of paper ... ...nts. In addition, air treatment has no effect on disease

  • Bryophyte And Pteropyte Life Cycles

    the sporophyte, and a multicellular haploid form, the gametophyte. Meiosis in mosses produces haploid spores. This process occurs in a sporangium, a capsule in fungi and plants in which meiosis takes place and haploid spores develop. After fertilization, the sporophyte zygote grows out of the parent gametophyte. At the end of this stalk is the sporangium. Meiosis occurs and the haploid spores disperse. In ferns, the mature sporophyte (2N) has small spots on the undersides of its leaves. These are

  • Mapping the Genes of Sordaria Fimicola

    1513 Words  | 7 Pages

    of this experiment is to examine the results of wild-type mutant crosses which influence the arrangements of ascospores in asci in the fungus Sordaria fimicola. These resulting arrangements help calculate the map distance between the centromere and spore color genes in Sordaria. My hypothesis was that due to so many group observations accounted in, the data will be underestimated and the results will not fit into the chi square table. A sample from Petri dish with both mutant stock cultures is observed

    contaminated sites. Effect of soil chemical properties on AMF spore count and diversity Soil HMM concentrations with the exception for Ni showed significant positive correlation to total spore count (P < 0.05), Glomus (P < 0.05) and Entrophospora (P < 0.05) spore count. In addition, As, Cd and Zn exhibited positive correlation to Glomus species richness (P < 0.05) and Shannon diversity index (P < 0.05) analyzed by DGGE (Table 3). Acaulospora spore count was found positively correlated with...

  • Cryptogramic Vascular Plants

    1311 Words  | 6 Pages

    known as photosynthesis. The plant kingdom is diverse and is made of plants of different biological diversity (Raven et al. 2005). Cryptograms or Seedless plants are vascular plants that do not produce seeds for dispersal but reproduce by windblown spores. In seedless plants the gametophyte and sporophyte are both independent phases in the plant’s life cycle. Like all vascular plants, cryptograms have true roots, stems and leaves. The sperm are flagellated and require water for reproduction. These

  • Coffee Rust Fungus of the Coffea Genus

    1631 Words  | 7 Pages

    Introduction The coffee bean is one of the world’s most widely utilized commodities touching almost every continent. In the book Coffee Rust: Epidemiology, resistance, and management Ajjamada Kushalappa asserts, “After petroleum coffee is the most important product in international world trade” (Kushalappa, Eskes 1989) Given this fact, it can be safe to assume the growing of this crop plays a large role in many countries economic stability. Coffee rust is a disease of the Coffee tree which has

  • My Search to Identify Padina Algae

    568 Words  | 3 Pages

    Using the ReefWatcher's field guide to native and alien Hawaiian algae published on the UH website, I identified the algae as of the genus Padina, however I am not quite sure which species it is. The most common species of Padina in Hawaii are the P. australis and P. japonica, and is sometimes referred to as "peacock's tail" because of its fan-like shape. Padina is a member of the class phaeophyceae, which is a class of brown algae. The peacock's tail alga is not harmful when eaten, however it can

    immediate action. Many improvements would come out of this new act. Many more species would live and not so many would become extinct. An example, would be, that the spotted owl eats voles, a small rodent. Voles eat fungi and disperse the fungi spores in their waste which the grown in the ground on the roots of the giant trees. Each organism plays a role in the healthy functioning of the forest. Landslides and flooding would not be as server, due to the fact that, forests

  • Asexual Reproduction: Spore Forming Bacteria

    1259 Words  | 6 Pages

    Spore forming bacteria Introduction The spore formation is kind of asexual reproduction which happens when the environmental conditions around the Bactria become not suitable for it and for protection too. Spores all the time haploid and unicellular and are generated by meiosis in the sporangium of a diploid sporophyte. Under convenient conditions the spore can use mitotic division to promote into a new organism, which produce a multicellular gametophyte, which eventually goes on to produce
