Clematis Evipo115 Compact Growth and Disease Resistance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Clematis plants in commercial cultivation lacked uniform and abundant purple flowers, vigorous and compact growth suitable for container culture, and improved disease resistance, which are essential qualities for nursery culture.
Innovation Solution
A new Clematis variety, 'Evipo115', was developed through controlled crossing, exhibiting compact growth, unique purple flowers, and enhanced disease resistance, achieved through asexual reproduction by vegetative cuttings and traditional layering, demonstrating stable transmission of characteristics.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional Clematis cultivars are used for commercial cultivation, then they can be grown and reproduced, but they lack uniform and abundant purple flowers, vigorous and compact growth suitable for container culture, and improved disease resistance
Solution Approach 1:
The patent applies parameter changes by selectively breeding for specific traits including compact growth habit (reducing plant size parameter), uniform flower color (standardizing color parameter), and disease resistance (improving biological resistance parameter). The resulting 'Evipo115' variety exhibits these modified parameters making it suitable for nursery culture while maintaining reliability against diseases.
2Adaptability or versatility
If Clematis plants are bred for compact growth suitable for container culture, then they become more suitable for nursery culture, but they may lose flower abundance and uniformity
Solution Approach 1:
The patent applies local quality by creating a variety where specific parts (flowers) exhibit enhanced properties (uniform purple color and abundance) while the overall plant structure remains compact. The 'Evipo115' variety displays localized intense purple pigmentation in flowers and uniform blooming patterns, compensating for the reduced overall plant size to maintain visual impact and flower abundance suitable for container culture.
3Shape
If Clematis plants are bred for uniform and abundant purple flowers, then aesthetic quality improves, but growth vigor and compactness may be compromised
Solution Approach 1:
The patent applies composite materials concept by combining multiple desirable traits into a single integrated variety. The 'Evipo115' variety composes uniform purple flower characteristics, compact growth habit, and vigorous health into a unified plant phenotype, where the traits work together synergistically rather than compromising each other, achieving both aesthetic quality and appropriate size for container culture.

AI summary
A new Clematis plant with a compact growth habit, profuse, purple flowers, and continuous summer flowering. The variety successfully propagates from softwood cuttings and is suitable for cultivation in commercial nursery culture. This new and distinct variety has shown to be uniform and stable in the resulting generations from asexual propagation from vegetative cuttings.
