Definitions

  • the present invention relates to the use of a fertilizer affecting plant biomass allocation. More specifically, the fertilizer is able to stimulate root growth, fine root development, increase the number of root tips and mycorrhiza development. Thus, the invention provides methods for using the fertilizer in order to stimulate root growth, fine root development, increase the number of root tips and mycorrhiza development. Furthermore, the invention provides a method for using the fertilizer for modulation of the root fraction of the biomass.
  • nitrogen effects on plant biomass allocation is that at higher rates of N supply, plants sense a decreased need for nitrogen uptake and hence for root growth but an increase need for carbon uptake and hence for shoot growth.
  • This simple relationship between nitrogen and carbon access and biomass allocation may be regulated through external cues and through sensing the levels of critical metabolites such as sucrose and glutamine within the plant.
  • AU659115 discloses a process to manufacture and the use of a fertilizer containing natural occurring L-amino acids, which are produced by enzymatic digestion of at least two proteolytic enzymes. AU659115 only discuss the advantage of using small molecules (amino acids) as nutrients to enhance the up take. None is taught about the use of a pure natural L-amino acid for stimulating root growth of plants. Furthermore, nothing is taught about the simultaneously development of mycorrhiza at the same time as it stimulates growth of the whole plant in these two patents.

Following 21 days of cultivation, plants were harvested, roots and shoots were separated and subsequently analysed for their content of N-15. The amount of N-15, expressed as atom % excess, in the two plant parts shows that nitrogen from L-Arginine is preferentially used for root growth;

  • the root mass fraction was significantly higher for plants supplied with a mixture of organic and inorganic nitrogen. This shows that, at equal or better growth, a higher root mass fraction can be achieved through cultivating plants on organic nitrogen or mixtures between inorganic and organic nitrogen compared to when plants are supplied with inorganic nitrogen only.
  • the current invention relates to the possibility to adjust plant biomass allocation to roots through use of specific amino acids as fertilizers during plant cultivation.
  • Mixtures in which specific amino acids forms a dominant part of the nitrogen in the fertilizers can thus be used to specifically increase root growth of plants and thus increase the root mass fraction of the produced plant.
  • Mixtures with a dominance of inorganic nitrogen forms can, accordingly, be used to specifically increase the shoot mass fraction of the plant.
  • mycorrhiza Many plants form symbioses with fungi, called mycorrhiza. It is well known that mycorrhizas develop poorly on plants given high amounts of nutrients (Smith, S. E., and D. J. Read. 1997. Mycorrhizal symbiosis, 2 nd Edition. Academic Press, New York, N.Y., USA.). Mycorrhizas are known to be beneficial for plants and promote plant uptake of mineral nutrients and of water as well as to protect plants from various pathogenes. Thus, cultivation of plants that, under natural conditions form mycorrhiza, should enable such symbioses to form. As stated above, however, high rates of nutrient addition may severely hamper or may not allow the development of mycorrhiza on cultivated plants.
  • mycorrhiza Several of the fungal species that form mycorrhiza are also known to form edible fruit bodies (mushrooms). However, production of fruitbodies will also be hampered by high rates of nutrient additions, i.e. the conditions that are used to stimulate plant growth.
  • the examples relates to the use of one amino acid and not two or more.
  • the fertilizer is not intended for invitro use and not for cut flowers.
  • An ideal fertilizer should hence stimulate not only plant growth but also growth of symbiotic fungi forming mycorrhiza. Furthermore, an ideal fertilizer should also allow for production of fungal fruit bodies.
  • plants cultivated on amino acids both displayed a high growth rate and vigorous development of mycorrhiza. The stimulation of mycorrhiza formation was found both on plants raised on amino acids and on plants raised on inorganic nitrogen sources (ammonium plus nitrate) but later supplied with amino acids.
