Solution Overview

Problem

Existing methods do not effectively predict the combined effects of applying multiple plant growth regulators, such as (S)-abscisic acid (ABA) and cytokinins, on plant growth and stress tolerance, particularly under abiotic stress conditions.

Innovation Solution

Applying a mixture of (S)-abscisic acid and one or more cytokinins to plants at a weight ratio of 10:1 to 1:10, specifically for cereal crops, to enhance growth and stress tolerance.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If multiple plant growth regulators are applied simultaneously to enhance growth and stress tolerance, then plant productivity and stress resistance are improved, but the complexity of predicting and controlling their combined effects increases

Engineering Contradiction:

Improvestress toleranceVSAvoidcomplexity of predicting combined effects

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The patent combines (S)-abscisic acid and cytokinins into a single mixture applied to plants. This merging of multiple growth regulators into one formulation simplifies the application process while achieving synergistic effects that improve both growth and stress tolerance, resolving the contradiction between effectiveness and prediction complexity

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The patent specifies a particular weight ratio range (10:1 to 1:10) of ABA to cytokinins in the mixture. By optimizing this parameter, the patent achieves reliable stress tolerance and growth improvement while providing a clear guideline that reduces the complexity of predicting and controlling the combined effects of the regulators

Inventive Principle:
