a substance which, in small concentrations, promotes root formation, bud growth, or certain other processes such as fruit ripening or leaf drop in plants.
substances found in places such as plant sprouts and human urine which stimulates growth in plant tissues promoting root formation.
One in a class of plant hormones that stimulates (among other things) cell elongation, secondary tissue growth, and fruit development.
(awk´ sin) [Gr. auxein: increase] • In plants, a substance (indoleacetic acid) that regulates growth and various aspects of development.
a plant hormone that controls elongation and other effects. J K Y Z
A naturally occurring hormone forming in plant cells in a wounded region
Collective term for naturally occurring organic substances which, in minute concentrations, influence the growth of plants favorably or otherwise. ( BCFT )
Growth hormones present in plants.
A group of plant growth regulators (natural or synthetic) which stimulate cell division, enlargement, apical dominance, root initiation, and flowering.
Regulator of growth synthesized essentially in the buds of the superior plants. Auxin has a role in the growth, the organogenesis, the cellular differentiation, the rooting. The cid 3- ndole cetic, (A.I.A ) , is a natural auxin .
a plant hormone that promotes root formation and bud growth
plant hormone. _The most important is IAA, which has roles in phototropism, apical dominance, fruiting and rooting
classification of plant hormones; Auxins are responsible for foliage and root elongation.
a plant hormone able to control growth
AWK-zin A type of plant hormone that elongates cells in seedlings, shoot tips, embryos, and leaves. 569
Auxins are growth hormones found in plants. Auxins induce phototropism, apical dominance, cell elongation and many other reactions.
A plant hormone that regulates growth.
Indole-3-acetic acid (IAA). Growth hormone produced by African Violets and other plants. Often used in organic rooting powders to encourage root growth. The concentration of auxin, at any specific part of an African Violet, is inversely related to the amount of light which that part of the plant receives. The reaction of auxin, particularly in the petioles, will make the plant grow towards the light. Thus, in addition to regulating growth, auxin helps to maximize the amount of light that an African Violet is receiving. Also see Phototropism.
plant hormones responsible for root growth and leaf growth.
Auxins are a class of plant growth substance (often called phytohormones or plant hormones). Auxins play an essential role in coordination of many growth and behavioral processes in the plant life cycle.
