The best regenerated shoots resulting from auxin
, cytokinin treatment or combinations were then transferred to MS medium at full or half strength of mineral, with or without NAA, at 0.
Differentiation processes depend upon endogenous factors, and growth substances such as auxins
and polyamines are believed to play a central role.
It is possible to substitute auxins
for achenes and cause a normal fruit to develop.
Vessel differentiation in the pedicel of apple and the effects of auxin
The sax 1 dwarf mutant of Arabidopsis thaliana shows altered sensitivity of growth responses to abscisic acid, auxin
, gibberellis and ethylene and is partially rescued by exogenous brassinosteroids.
Cytokinins, like auxins
and gibberellins, were also not initially isolated from a plant source.
Moreover, microorganisms of certain geographical area might vary in their genetic potential to produce auxins
under given environmental conditions.
In an attempt to reconcile the longer term inhibitory effect of auxin
on bean leaves with the possibility of shorter term stimulatory effects, I re-examined, in high resolution continuous recordings, the effect auxin
on leaf expansion of bean leaves.
are widely used for root development, they can promote cell division and elongation and stimulate lateral budding depending on the used concentration (DAVIS, 1987).
Changes in the concentrations of auxins
and polyamines during rooting of in vitro propagated walnut shoots.
Numerous microbes have been reported to produce auxins
in solution or in soil (Dobbelaere et al.
play an important role in fruit set and growth, and the genes related to the biosynthesis, transport and response of auxin
are associated with fruit development.
The explants were pretreated with auxin
solutions or the explants were inoculated in culture medium containing auxins
As weak light falls on one side of the plant's shoot, auxins
flow away from it and into cells on the darker side.
Young rods above 20 cm have higher content of nutrient reserves, increasing the resistance to external factors period, with easier emission of root, regardless of the use of auxins
