Buddleia Buddaplav Compact Growth Habit Breeding
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need for Buddleia davidii cultivars with compact and well-branched habits that can serve as effective ornamental plants in various settings, as existing varieties either lack desired characteristics or are not stable under propagation.
Innovation Solution
The development of the 'Buddaplav' cultivar through controlled breeding, combining traits from an unnamed breeder seedling and 'Boscranz' varieties, resulting in light purple flowers, medium green foliage, and a moderately vigorous, compact growth habit, which is stable through asexual propagation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If existing Buddleia varieties are used, then they can be grown as ornamental plants, but they lack compact and well-branched growth habits
Solution Approach 1:
The patent applies parameter changes by selecting and breeding plants with specific growth habit parameters (compactness, branching density) to develop cultivars that meet ornamental requirements. The breeding program specifically selected for plants exhibiting compact, mounded forms with well-branched structures, transforming the growth habit parameters of Buddleia davidii to achieve desired ornamental characteristics.
2Manufacturing precision
If new cultivars are developed through breeding, then desired characteristics can be achieved, but stability under propagation may be compromised
Solution Approach 1:
The patent employs terminal stem cuttings as a propagation method that is both reliable and maintains characteristic consistency. This propagation approach uses readily available stem material from parent plants to produce genetically identical offspring, ensuring that the compact growth habit and other desired traits are stably transmitted across generations without requiring complex propagation systems.
3Shape
If compact growth habit is selected for, then ornamental value is enhanced, but plant vigor may be reduced
Solution Approach 1:
The patent applies local quality by differentiating between overall plant compactness and local growth vigor. The selected cultivars exhibit compact, mounded forms at the plant level while maintaining vigorous growth characteristics in local areas such as stem strength, branching activity, and flowering production. This allows the plants to achieve ornamental compactness without sacrificing the vigor needed for healthy growth and continuous blooming.
