Clematis Evipo084 Compact Growth and Red Flower Uniformity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Clematis plants in commercial cultivation lacked uniform and abundant red flowers, vigorous yet compact growth suitable for container culture, and improved disease resistance.
Innovation Solution
A new Clematis variety, 'Evipo084', was developed through controlled crossing, exhibiting Red-Purple Group 59A colored tepals, moderate vigor, and enhanced disease resistance, suitable for nursery culture and container growth.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If Clematis plants are bred for vigorous growth, then productivity and abundance of flowers improve, but the plants become too large for container culture
Solution Approach 1:
The patent applies parameter changes by selectively breeding for specific growth parameters - achieving vigorous flowering productivity while controlling plant height to 60-80 cm. The hybridization process modified growth parameters to create a balance between flower abundance and compact size suitable for container culture.
2Manufacturing precision
If Clematis plants are bred for uniform red flowers, then flower quality improves, but disease resistance may be compromised
Solution Approach 1:
The patent applies composite materials principle by creating a hybrid plant combining genetic traits from two different parent varieties - one contributing uniform red flower characteristics and the other contributing disease resistance. The resulting 'Evipo084' is a composite genetic structure that integrates both desired traits.
3Adaptability or versatility
If Clematis plants are bred for compact growth, then adaptability to container culture improves, but flower abundance may decrease
Solution Approach 1:
The patent applies parameter changes by optimizing the relationship between plant size parameters and flowering parameters. The hybrid 'Evipo084' achieves a specific parameter combination - 60-80 cm height with multiple flowers per node, creating a density parameter that maximizes flower abundance within compact dimensions suitable for containers.
