Question

Which of the following is not a function of auxins?
A. promoting apical dominance
B. promoting cell elongation in stems
C. promoting the growth of lateral buds
D. promoting the growth of new roots.

Answer 1

Well the functions of auxins are:


Stimulates cell elongation
Stimulates cell division in the cambium and, in combination with cytokinins in tissue culture
Stimulates differentiation of phloem and xylem
Stimulates root initiation on stem cuttings and lateral root development in tissue culture
Mediates the tropistic response of bending in response to gravity and light
The auxin supply from the apical bud suppresses growth of lateral buds
Delays leaf senescence
Can inhibit or promote (via ethylene stimulation) leaf and fruit abscission
Can induce fruit setting and growth in some plants
Involved in assimilate movement toward auxin possibly by an effect on phloem transport
Delays fruit ripening
Promotes flowering in Bromeliads
Stimulates growth of flower parts
Promotes (via ethylene production) femaleness in dioecious flowers
Stimulates the production of ethylene at high concentrations
