Corn Growth Regulation via GA3 ABA Ratio
Solution Overview
Problem
Current methods for improving corn growth and yield are limited by the variability in effects of plant growth regulators like gibberellic acid (GA3) and abscisic acid (ABA), particularly in predicting their combined effects and achieving optimal ratios for maximizing yield without adverse side effects.
Innovation Solution
Applying a specific weight ratio of GA3:ABA ranging from 10:1 to 14:1, preferably 12.8:1, to corn plants during the V4 to V6 growth stage, which can include genetically modified corn varieties, to enhance growth and yield under both stressed and non-stressed conditions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If GA3 is applied to increase plant height, then corn growth is improved, but excessive application causes green snap or lodging
Solution Approach 1:
The patent changes the concentration ratio parameter of plant growth regulators from conventional single-hormone application to a specific dual-hormone ratio (GA3:ABA from 10:1 to 14:1). This parameter modification allows achieving desired growth promotion while suppressing adverse effects through the balanced hormonal interaction.
Solution Approach 2:
ABA acts as an intermediary substance that modulates the effects of GA3. By introducing ABA as a mediating hormone, the patent achieves indirect control over GA3's actions, allowing growth promotion while preventing excessive elongation and associated harmful effects through the antagonistic interaction between the two hormones.
2Reliability
If ABA dose is increased to improve stress resistance, then drought tolerance is enhanced, but excessive ABA reduces plant growth and yield
Solution Approach 1:
The patent modifies the concentration parameter of ABA from high-dose single application to a controlled low-dose application within a specific ratio range (GA3:ABA from 10:1 to 14:1). This parameter optimization maintains stress resistance benefits while minimizing growth suppression effects.
Solution Approach 2:
The patent applies different hormonal qualities to different physiological needs: GA3 provides growth promotion while ABA provides stress resistance. By distributing these different hormonal qualities in a specific ratio, the patent achieves both growth and stress resistance without the adverse effects of excessive single-hormone application.
3Adaptability or versatility
If GA3 and ABA are applied simultaneously, then multiple effects are achieved, but predicting the combined effect is difficult
Solution Approach 1:
The patent simplifies the complexity of predicting combined hormone effects by establishing a specific numerical ratio parameter (GA3:ABA from 10:1 to 14:1). This parameter standardization transforms the unpredictable interaction into a controllable and predictable application protocol.
