A plant hormone connection with the disease was based on the fact that exogenous auxins
and cell-division factors were not required for cell cultures of tumors but were for nontumorous cultures (Brown & Gardner, 1936; Klein & Link, 1952).
The fact that methylotrophic bacteria promote seed germination and the growth of seedlings suggests that these bacteria may synthesize not only cytokinins but also other phytohormones for instance auxins
Responses from cultivar 'Hibrida Superex' indicate that the product had an effect similar to auxin
The number of roots was proportional to the concentrations of auxins
except at the high concentration of auxins
IAA and the synthetic auxins
NAA ([alpha]-naphthalene acetic acid), and 2-NAA ([beta]-naphthalene acetic acid) were applied in solution at various concentrations directly to leaves.
The tip of the cutting contains lots of them, but if you nip off the tip to make a bushy plant, auxins
are concentrated under the leaf node where you've cut and help the cutting produce roots there.
Effect of some auxins
on growth of damask rose cuttings in different growing media.
Cytokinins are produced in the cap of the main root and, like the auxins
, they positively control the root geotropic curvature (MIYAWAKI et al.
produced by rhizobacteria can influence plant growth, including root development which improve uptake of essential nutrients thus increasing plant growth .
The researchers at the Salk Institute for Biological Studies found that a protein known as phytochrome interacting factor 7 (PIF7) serves as the key messenger between a plant's cellular light sensors and the production of auxins
, hormones that stimulate stem growth.
2006) showed how auxins
play a stimulatory role during the induction and differentiation of apogamous embryo development in D.
It is worth noting that there were other blends of synthetic auxins
at the time of the Vietnam War whose containers were recognized by their colors, such as Agent Purple and Agent Pink.
In addition, sucrose, inoculum density, auxins
, and aeration also play a very crucial role in the production of gymnemic acid through bioreactor-dependent cell growth (Lee et al.
Further, LSBM fortified with different concentrations of auxins
(2,4-D and NAA) were used to induce callus from the vegetative bud explant.
Plant growth regulators such as auxins
(2,4-D and NAA) and cytokinins (BA and kin) have different effects on plant growth and are often crucial factors in secondary metabolite accumulation (DiCosmo and Towers, 1984).
