Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In modern agriculture, seed production plants grown in controlled environments face challenges in maximizing seed yields while maintaining or improving seed quality, as improvements in yield often negatively impact quality.
Innovation Solution
Subjecting day-neutral seed production plants to supplemental far-red light, particularly after fertilization and during fruit development, to enhance seed quality by adjusting the phytochrome stationary state and promoting shade avoidance responses.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If seed production plants are grown in controlled environments to maximize seed yield, then productivity is improved, but manufacturing precision deteriorates due to negative effects on seed quality
Solution Approach 1:
The patent applies parameter changes by modifying the light spectral composition, specifically adding far-red light (700-800 nm) to the growth environment. This changes the photomorphological response of the plant through phytochrome regulation, simultaneously improving both seed yield and seed quality by altering the physiological state during fruit development
2Device complexity
If conventional lighting is used in controlled environments, then device complexity is minimized, but productivity deteriorates due to inability to optimize seed yield and quality
Solution Approach 1:
The patent introduces far-red light supplementation to modify the spectral parameters of the lighting environment. This relatively simple parameter addition triggers phytochrome-mediated physiological changes that enhance both yield and quality, achieving productivity improvement without substantial increases in device complexity
