Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Celery cultivars face challenges such as bolting, disease susceptibility, and environmental stress tolerance, which affect yield and marketability, particularly in regions with varying temperature and moisture conditions.
Innovation Solution
Development of the celery cultivar TBG 35, which exhibits improved bolting tolerance, disease resistance, and adaptability to different environmental conditions, achieved through breeding techniques including recurrent selection, backcrossing, and genetic modification, resulting in enhanced yield and quality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If celery is grown in winter regions with cool temperatures, then yield and quality are improved, but bolting occurs which reduces marketability
Solution Approach 1:
The patent applies parameter changes by modifying the genetic parameters of the celery plant through selective breeding. Specifically, it has developed a variety with changed vernalization requirements - the plant requires a specific number of cold hours (100-200 hours at 32-40°F) to trigger bolting, which can be controlled through breeding. This genetic parameter modification allows the celery to tolerate winter cooling temperatures for yield improvement while preventing premature bolting that would reduce marketability.
2Productivity
If celery is transplanted earlier to extend growing season, then yield increases, but exposure to cold temperatures increases causing bolting
Solution Approach 1:
The patent converts the harmful effect of cold temperatures into a beneficial control mechanism. Instead of viewing cold temperatures as a harmful factor that causes premature bolting, the invention uses a specific cold requirement (100-200 hours at 32-40°F) as a positive trigger for controlled bolting at the appropriate time. This allows earlier transplanting for extended growing season and higher yield, while the controlled cold requirement ensures bolting occurs only when desired, not prematurely.
3Object-affected harmful factors
If celery varieties are selected for bolting tolerance, then marketability is improved, but adaptability to different regions is reduced
Solution Approach 1:
The patent achieves universality by developing a celery variety with multi-functional characteristics. The variety combines bolting tolerance (requiring 100-200 cold hours) with adaptability to multiple growing regions and conditions. It performs well in both winter and summer production systems, and can be grown successfully in diverse environments from Florida to California. This multi-functionality allows a single variety to serve multiple purposes across different geographic locations, resolving the contradiction between bolting tolerance and environmental adaptability.
4Duration of action of moving object
If celery is grown in southern regions with warmer climates, then growing season is extended, but disease pressure increases
Solution Approach 1:
The patent applies the principle of using temporary protective measures through the development of varieties with inherent disease resistance characteristics. The variety TBG 35 and related lines possess genetic resistance to major diseases such as brown stem rot and bacterial blight, which provides temporary protection during the extended growing season in southern regions. This genetic resistance acts as a disposable protective mechanism that prevents disease establishment without requiring additional protective infrastructure.
