Cercis canadensis SEIRB Zig-Zag Growth Pattern
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need for a distinct cultivar of Cercis canadensis that exhibits unique growth patterns, flower colors, and plant habits, which are not adequately met by existing cultivars like 'Ruby Falls' and 'Merlot', particularly in terms of zig-zag stem growth and semi-weeping plant habit.
Innovation Solution
The development of the new cultivar 'SEIRB' of Cercis canadensis, characterized by a zig-zag growth pattern, semi-weeping plant habit, deep pink flowers, and dense form, achieved through asexual propagation by side veneer grafting, distinguishing it from other cultivars.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If existing Cercis canadensis cultivars like 'Ruby Falls' and 'Merlot' are used, then established propagation methods can be applied, but they lack unique growth patterns and plant habits
Solution Approach 1:
The patent introduces a new cultivar with fundamentally different growth parameters - specifically the zig-zag stem growth pattern and semi-weeping plant habit - that distinguish it from existing cultivars. This parameter change in growth morphology provides the desired ornamental diversity while maintaining cultivar stability through asexual propagation
2Stability of the object's composition
If asexual propagation by side veneer grafting is used, then stable characteristics are maintained, but propagation complexity increases
Solution Approach 1:
The side veneer grafting process requires preliminary preparation of scion and rootstock materials before the actual grafting operation. The scion wood is prepared in advance with specific dimensions and orientation to ensure successful propagation while maintaining the distinctive zig-zag growth pattern and other cultivar characteristics
