Auxin is the hormone that activates and directs new cell division and food movement in a plant:
• Auxin is primarily produced in new apical meristem tissue in the leaves.
• Auxin is responsible for cell division leading to active growth of the plant.
• Auxin also directs the movement of photosynthates (food, sugar) throughout the plant. As the plant grows more vigorously and more auxin is produced in the leaves, the movement down to the roots increases. This directs more food from the roots to the upper part of the plant.
• As the plant reaches its most rapid and vigorous vegetative growth stage, the high amount of auxin transported down to the roots tends to inhibit cell division in the roots. This resulting loss in root vigour causes the plant to begin senescence (cell death).
• After a plant begins senescence, auxin levels build in the fruiting buds and fruiting areas of the plant. This triggers an increase in the amount of ethylene and ABA in the fruit, grain, and storage cell tissues, which initiates ripening.
Manage your Auxin levels with Stoller’s Fortified Stimulate® Yield Enhancer, a combination of four plant growth hormones including two forms of Auxin (IAA & IBA).
Use as a seed treatment, in-furrow, or foliar to manage hormone levels throughout the full growing season. For more information click here.
