Effect of plant growth hormones and regulators?

Need of Coal Testing Labs

Hormones are produced naturally by plants, while plant growth regulators are applied to plants by humans. Plant hormones and growth regulators are chemicals that affect:

  • Flowering.
  • Aging
  • Root growth.
  • Distortion and killing of organs.
  • Prevention or promotion of stem elongation.
  • Color enhancement of fruit.
  • Prevention of leafing, leaf fall or both.
  • Many other conditions.

Plant growth regulators may be synthetic compounds, such as IBA and Cycocel, that mimic naturally occurring plant hormones, or they may be natural hormones that were extracted from plant tissue, such as IAA.

Why Plants need hormones?

  • Plants need hormones at very specific times during plant growth and at specific locations. They also need to disengage the effects that hormones have when they are no longer needed. The production of hormones occurs very often at sites of active growth within the meristems, before the cells have fully differentiated. After production, they have sometimes moved to other parts of the plant, where they cause an immediate effect; or they can be stored in cells to be released later. Plants can also break down hormones chemically, effectively destroying them. Plant hormones frequently regulate the concentrations of other plant hormones.

Testing at Anacon Lab

Testing of these hormones is important study the growth of plant. At Anacon Laboratories few procedures are followed like to screen for the phytohormones producing soil isolates and to check the ability of these phytohormones to promote plant growth. Isolation and characterization of microorganisms from soil sample.

  • Screening for phytohormones production in these isolates.
  • Confirmation by thin layer chromatography (TLC) and high performance liquid chromatography (HPLC)
  • Field study to demonstrate the ability of these phytohormones to promote plant growth.
