Physocarpus SMNPMS Cultivar Compact Growth and Leaf Color
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing Physocarpus opulifolius cultivars lack compact, upright growth habits with attractive leaf coloration and sufficient mildew resistance, limiting their garden performance and adaptability.
Innovation Solution
A new Physocarpus opulifolius cultivar 'SMNPMS' was developed through controlled breeding, exhibiting a compact, upright, and freely branching habit with dark greyed purple-colored leaves, achieved via open-pollination and stabilized through asexual reproduction by softwood stem cuttings.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If traditional Physocarpus opulifolius cultivars are used, then they have established growth patterns, but they lack compact and upright growth habits with attractive leaf coloration
Solution Approach 1:
The patent applies parameter changes by selecting and breeding for specific morphological parameters (compact size, upright orientation, leaf coloration) to transform the growth habit of Physocarpus opulifolius from traditional spreading forms to the desired compact upright form with dark greyed purple leaves
2Reliability
If existing cultivars are propagated, then reproduction is established, but mildew resistance and unique characteristics are not maintained across generations
Solution Approach 1:
The patent applies preliminary action by conducting controlled open-pollination breeding programs that pre-select for mildew resistance and characteristic stability before propagation, ensuring these traits are embedded in the genotype prior to asexual reproduction
Solution Approach 2:
The patent applies copying through asexual reproduction by softwood stem cuttings, which creates genetically identical copies of the selected plant that reliably maintain both mildew resistance and unique characteristics across successive generations
3Adaptability or versatility
If open-pollination breeding is used, then genetic diversity is achieved, but the stability and uniformity of unique features across generations may be compromised
Solution Approach 1:
The patent applies preliminary action by conducting controlled open-pollination breeding that pre-selects for desired traits, then stabilizing the resulting genotype through asexual reproduction to ensure feature stability
Solution Approach 2:
The patent applies copying through asexual reproduction by softwood stem cuttings, which creates genetically identical copies that maintain the genetic diversity achieved through open-pollination while ensuring stable transmission of unique features across generations
