Do the roots produce hormones rhizogenic

Postby aply123 » Tue Jul 18, 2006 7:11 pm

Hello has all
During an experiment that we led to the laboratory we noticed that if we crush roots in distilled water and that then we immerse stems that will develop tufts very dense of root. We concluded that the roots can contain a hormone different from the auxines already known like AIA or gébéreline.
Question: Do the roots produce hormones rhizogenic

do you mean what stimulates the cells to produce roots?

The name of the hormone? or are you saying it is a yet unknown? :?

As far as I remember polyphenols also boost roots to grow.

Check the tutorials:

Auxins

Auxins are hormones involved in plant-cell elongation, apical dominance, and rooting


Synthetic Auxins

Chemists have synthesized several inexpensive compounds similar in structure to IAA. Synthetic auxins, like naphthalene acetic acid, of NAA, are used extensively to promote root formation on stem and leaf cuttings

Thank you for the answers.
For linn: I does not say that it is unknown, but here I give only the result of an experiment. Another report If we put the roots on a sheet soaked by the extract of the roots, the roots shows a negative geotropism. The roots behave like stems.
