Auxin-Dominant Plant Growth Composition for Variable Field Conditions
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing plant growth regulator (PGR) compositions are ineffective in promoting consistent plant growth across varying environmental conditions, particularly due to weather and soil variability at the time of planting.
Innovation Solution
A plant growth composition comprising a mixture of inert compounds and an active component combination of auxin, gibberellin, and cytokinin, with auxin being dominant, is applied in-furrow and/or foliarly to enhance plant growth, optimized through extensive experimentation across different climates.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional PGR formulations are applied to seeds and young plants, then plant growth stimulation is achieved, but the effectiveness is severely reduced by weather and soil conditions at the time of planting
Solution Approach 1:
The patent applies composite materials by combining multiple plant growth regulators (auxin, gibberellin, and cytokinin) in a specific formulation. This composite PGR composition leverages the synergistic effects of different hormone types to achieve reliable plant growth stimulation that is not dependent on单一 substance effectiveness, thereby overcoming environmental variability.
Solution Approach 2:
The patent utilizes parameter changes by optimizing the concentration ratios of auxin, gibberellin, and cytokinin in the PGR formulation. By adjusting these chemical parameters and their interactions, the composition achieves enhanced stability and effectiveness across varying weather and soil conditions, making the growth stimulation more reliable.
2Adaptability or versatility
If a single-type PGR composition is used, then the formulation is simple, but it cannot provide consistent growth promotion across varying environmental conditions
Solution Approach 1:
The patent employs composite materials by formulating a multi-component PGR system containing auxin, gibberellin, and cytokinin. This composite approach enables the composition to adapt to varying environmental conditions through the combined actions of different plant hormones, achieving consistent growth promotion despite increased formulation complexity.
Solution Approach 2:
The patent applies universality by designing a PGR composition that performs multiple functions simultaneously - promoting root development, shoot growth, and overall plant vigor through different hormonal mechanisms. This multi-functional formulation ensures consistent effectiveness across diverse environmental conditions without requiring multiple separate applications.

AI summary
Plant growth compositions include a mixture of inert compounds and an active component combination of auxin, gibberellin and cytokinin. The plant growth compositions are auxin-dominant, and the ratio of cytokinin to auxin in the active component combination ranges from about 1:10.5 to about 1:4.5. The amount of cytokinin ranges from about 0.1 to 10 wt % by weight of the active component combination in plant growth compositions formulated for in-furrow application to corn plants. Methods of improving plant growth involve in-furrow, seed and/or foliar application of one or more plant types with a plant growth composition. Improvements in plant growth include increases in the average number of bushels produced per acre.
