Stage-Specific Plant Growth Regulator Compositions
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing plant growth regulator (PGR) applications are suboptimal as they are typically applied uniformly across multiple stages of plant development, leading to wasted product and untapped growth potential, as they do not account for the specific growth requirements of different developmental stages.
Innovation Solution
Formulating PGR compositions with specific ratios of auxin, gibberellic acid, and cytokinin, and adjusting these ratios at distinct growth stages, such as the VE and V4 stages, for seed-applied or foliar applications to optimize corn plant growth, including in-furrow and foliar applications with varying cytokinin, auxin, and gibberellic acid proportions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the same PGR product is applied uniformly across multiple stages of plant development, then application simplicity is maintained, but product waste occurs and growth potential remains untapped
Solution Approach 1:
The patent segments the plant development process into distinct growth stages (vegetative, reproductive, maturation) and assigns different PGR formulations to each stage. This segmentation allows optimization of growth stimulation for specific developmental needs while preventing product waste from inappropriate applications.
Solution Approach 2:
The patent implements dynamic adjustment of PGR composition and application timing based on plant developmental stage. The formulation transitions from higher cytokinin levels during vegetative growth to balanced hormone profiles during reproductive stages, enabling responsive optimization of growth stimulation.
2Device complexity
If the same PGR product is applied uniformly across multiple stages of plant development, then operational complexity is reduced, but growth optimization is lost
Solution Approach 1:
The patent employs preliminary action by providing pre-formulated PGR products with optimized hormone compositions tailored to specific growth stages. This allows growers to select the appropriate formulation based on plant development stage without requiring complex formulation adjustments, maintaining operational simplicity while achieving growth optimization.
Solution Approach 2:
The patent utilizes parameter changes by varying the concentration ratios of plant hormones (cytokinin, auxin, gibberellin) in different formulations according to growth stage requirements. This enables optimization of growth responses for each developmental phase while maintaining a structured application framework.
3Productivity
If PGR compositions are adjusted at distinct growth stages, then growth potential is maximized, but application complexity increases
Solution Approach 1:
The patent creates universal PGR formulations that can be applied across multiple growth stages with a single product design. Each formulation is engineered to provide appropriate hormone balance for its target stage, eliminating the need for complex custom mixing while maintaining growth optimization capabilities.
4Manufacturing precision
If PGR compositions are adjusted at distinct growth stages, then growth precision is improved, but formulation complexity increases
Solution Approach 1:
The patent applies parameter changes by systematically varying hormone concentration ratios in formulations to match specific growth stage requirements. This scientific approach to formulation design achieves precise growth stimulation for each developmental phase while maintaining reproducible manufacturing processes.

AI summary
Methods of improving plant growth involve applying a first growth composition to a plant or part thereof during a first growth stage. The first growth composition includes a first active component combination comprised of auxin, gibberellin and cytokinin. The amount of cytokinin is less than the amount of auxin and gibberellin. The method also involves adjusting the amount of auxin, the amount of gibberellin, and/or the amount of cytokinin after the first growth stage, and applying a second growth composition to the plant or part thereof during a second growth stage. The second growth composition can include a second active component combination, different than the first, that includes a second amount of auxin, a second amount of gibberellin, and a second amount of cytokinin. In some examples, the method can also involve growing the plant to maturity, thereby improving growth of the plant.
