Essential Plant Nutrients - 0 views

  • Plants require 13 mineral nutrient elements for growth
  • Macronutrients (nitrogen, phosphorus, potassium, calcium, magnesium and sulfur) are plant nutrients required in the largest amount in plants. Micronutrients (iron, copper, manganese, zinc, boron, molybdenum and chlorine) are required in relatively smaller amounts. Additional mineral nutrient elements which are beneficial to plants but not necessarily essential include sodium, cobalt, vanadium, nickel, selenium, aluminum and silicon

      Nutrients (in the soid) are needed either in large amounts (macronutrients), medium amounts (micronutrients), or in trace amounts

  • Five types of deficiency or toxicity symptoms are observed:

      Here are the visible signs if the soil does not have enough of or too much of a nutrient.

      Plants can be damaged is there is too much of one nutrient (toxicity) or not enough of a nutrient (deficiency).
  • A nutrient deficiency occurs when the nutrient is not in sufficient quantity to meet the needs of the growing plant. Nutrient toxicity occurs when a plant nutrient is in excess and decreases plant growth or quality
  • Essential plant nutrients: their relative amounts in plants, functions and classification

      This table may be helpful in determining a topic for an experiment. You would only want to choose one nutrient with which to run an experiment.

Plant hormone and growth regulators - 0 views

  • (Table 5)
  • Hormones are produced naturally by plants, while plant growth regulators are applied to plants by humans
    • Pascale Michelon
       
      This is interesting because it shows you that if you want to manipulate hormones in an experiment you can use plant growth regulators to mimic the action of hormones.
  • ...3 more annotations...
  • There are five groups of plant-growth-regulating compounds: auxin, gibberellin (GA), cytokinin, ethylene, and abscisic acid (ABA).
  • Ethylene is unique in that it is found only in the gaseous form. It
  • induces ripening, causes leaves to droop (epinasty) and drop (abscission), and promotes senescence.
    • Pascale Michelon
       
      The effects of ethylene (promotion of both aging/death and ripening) may explain why just one bad apple in a basket may spoil the whole bunch.
  •  
    Plant hormones and growth regulators are chemicals that affect flowering; aging; root growth; killing of leaves; prevention or promotion of stem elongation; color enhancement of fruit; prevention of leafing and/or leaf fall; etc.

Common Mistakes to Avoid for New Gardeners - New to Gardening - 0 views

  • Overcrowding Overcrowding plants doesn't do it any favors. Plants need room to breathe and good air circulation. They also need light to reach them and planting too densely blocks the plants ability to reach it's full potential. Overcrowding stresses plants and makes them more prone to disease.

  • Sixteen chemical elements are required for the growth of all plants: carbon, oxygen, and hydrogen (these three are obtained from carbon dioxide and water), plus nitrogen, phosphorus, potassium, calcium, magnesium, sulfur, iron, manganese, zinc, copper, boron, molybdenum, and chlorine. Some plant species also require one or more of the elements cobalt, sodium, vanadium, and silicon.
