Transcript of "Economical importance of bryophytes"

  1. 1. Importance of Bryophytes Group members Mahnoor Khawaja Fizza Shahid
  2. 2. Importances of bryophytes Ecological Economicalimportances importances By Fizza By Mahnoor
  3. 3. Introduction to Bryophytes• Bryophyte is a traditional name used to refer to all embryophytes (land plants ) that do not have true and are therefore called vascular plants.• There are about 25,000 different species of bryophytes in the world today. Although these plants are small in size, they are one of the largest groups of land plants and can be found almost everywhere in the world.
  4. 4. Occurrences of Bryophytes On tree In the trunks forest Damp Damp areas rocks
  5. 5. Types of Bryophytes mosses liverwort hornwort
  6. 6. Economical Importances of bryophytes PreservativeSource of fuel Horticulture, agent House pharmaceuticalHousehold Uses Construction industry Moss industry
  7. 7. Bryophytes as Fuel• Liverworts and mosses have long been tried and used as a fuel in developed countries like Finland, Sweden, Ireland, West Ger-many, Poland and Soviet Union.• Peat a brown, soil-like material characteristic of boggy, acid ground, consisting of partly decomposed vegetable matter.• Peat is suitable for production of low and intermediate BTU gas as well as hydrogen, ethylene, natural gas, methanol and Fisher Tropsch gasoline.• Peat mosses are best suited for the production of methane, and peat is likely to become an important source of fuel for production of heat,methane, or electricity in the future.
  8. 8. Pie chart showing peat use as fuel
  9. 9. Horticultural Uses• There is a long tradition of use of bryophytes in horticulture as soil additives, because of their high water holding capacity and to air. Peat is an important soil conditioner and is commonly used for agricultural and horticultural purposes around the world.
  10. 10. Use of peat in horticulture in UK to increase yield
  11. 11. Bryophytes as ornamental plant• Bryophytes have also been used for green house crops, potted ornamental plants and seedlings, and in garden soil.
  12. 12. As preservative agent Bryophytes have excellent power to absorb moisture and can act as a goodpreservative agent . They not only help to prevent food but also help to preserve death bodies.
  13. 13. Moss industry• Moss industries in France manufacture moss carpets in various sizes.• They are easy to fix along the• roads, lawns, play grounds, etc.• In Sri Lanka,a wide range of eco-friendly products such as coir pots, coir fiber pith (coco - peat), moss sticks, hanging wire baskets and basket liners are made using bryophytes.
  14. 14. House Construction•These tiny plants are used in the construction of houses andtheir furnishings.•At Kapkot in the Himalayas, villagers use moss mats withshrubs, grasses, and bamboo to make a pharki, a kind of doorplaced at the openings of their temporary huts.Sphagnumpeat, peatcrete and peatwood are the newmaterial use for making houses ,they are low cost and easyto transport.
  15. 15. . Household Uses •The Himalayans also use mosses as insect repellents when storing food. •Local mosses and liverworts are dried, made into a coarse powder that is sprinkled over grains and other goods to be stored in containers.
  16. 16. . Fibre industries •Mosses are mixed with wool to make cheap clothes. •They are used in decoration of net bags and other objects. •Women also wear their steam like structure in their hair and as decorations in bracelets . •Used in hiking boats to absorb odour and moisture. •Used in lining of diapers to improve absorbing power.
  17. 17. Medicinal Uses Sphagnol’chilblains, scabies, acne and other forms of skin diseasesUse for curing for allaying arising Skin Help to curefrom insect bites. treatment ringworms. Ash of moss is mixed with honey and fat to treat cuts, burns and wounds
  18. 18. Medicines cystitis cardio- vascular bronchitis system China in the business oftonsillitis medicines tympanitis made up of bryophytes
  19. 19. Use in Biotechnology• Transgenic Physcomitrella are now being used to produce ‘blood-clotting factor IX’, for the treatment of haemophilia’ B and other proteins

  21. 21. Role of Bryophytes in Different Ways PEAT FOOD AND POLLUTION SEED BEDSFORMATION SHELTER WATER SOIL EROISION AND NUTRIENT INDICATOR OFCONSERVATION INDICATOR OF RECYCLING soil PH ACID RAIN
  22. 22. PEAT • Peat is a brown dark colourFORMATION spongy matter produce due to compression and carbonization by deposits and water. • Sphagnum and other mosses form peat. • used in horticulture, making ethyl alcohol and illuminating gas.
  23. 23. • Bryophyte mats may provideSeed Beds ideal sites for the germination of vascular plant seeds. • Bryophyte mat can provide a fairly stable micro-habitat, protected against the drying effects of sun and wind and the extremes of temperature. • Therefore a seed that falls into such a carpet could find itself in a relatively sheltered micro- habitat that is conducive to successful germination.
  24. 24. Food AND SHELTER• Many animals make use of • In Vertebrates the range of bryophytes. Numerous associations is much less. invertebrates eat bryophytes, • Northern Corroboree Frog are lay their eggs on them or found near Sphagnum bogs . shelter in them. They form a These endangered frogs breed vital part of the construction in Sphagnum bogs in the material of the nest of some alpine and sub-alpine areas birds but move away from boggy areas outside of the breeding season.
  25. 25. POLLUTION• Pollutants come in many forms from both urban and rural areas. Sulfur dioxide has been a significant industrial pollutant for many years, being a by-product of the use of high sulfur fuels.• Sulfur dioxide is very damaging but some bryophytes are highly tolerant of sulfur dioxide pollution and examples of these are the mosses Funaria hygrometrica and Bryum argenteum
  26. 26. SOIL CONSERVATION• Bryophytes form a mat and prevent soil erosion.• The intertwined moss stems and rhizoids bind soil particles firmly.• Hold large amount of water and reduce run off.
  27. 27. Water Erosion and Nutrient RecyclingWATER EROSION and nutrientrecycling: Diagram• Bryophytes on tree trunks absorb rainwater thats flowing down the trunk and those hanging like curtains absorb water, both from rain and help maintain a humid atmosphere and so greatly influence the micro- climate.• Bryophytes will also trap any nutrients that are dissolved in the rain or mist droplets, in many cases trapping nutrients that would otherwise be washed away. Living bryophytes make use of the nutrients they trap and dead, decaying bryophytes release nutrients to the surrounding plants. In these ways bryophytes play an important role in nutrient recycling.
  28. 28. Indicator of soil ph• Liverworts and mosses are good indicators of soil ph.• Some bryophytes can grow in narrow and specific range of ph so therefore their presence can be used as an indicator of soil ph.• For example campylopus paradxus indicates acidic soil.
  29. 29. Indicator of acid rain• Mosses are good indicators of acid rain because they lack a protective epidermis and cuticle hence are most suspectible than vascular plants.• For example neckera crispa indicates high ph as like of acid rain.
