Hydrangea Levana Stem Strength and Inflorescence Uniformity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing Hydrangea cultivars lack strong stems and uniform, large inflorescences, and are susceptible to pathogens and pests, limiting their reliability and aesthetic appeal.
Innovation Solution
A new cultivar, 'Levana', developed through planned breeding, featuring upright habit, strong and sturdy stems, large lacecap-type inflorescences with fragrant white flowers, and improved resistance compared to parent cultivars, achieved through asexual reproduction by softwood cuttings.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If existing Hydrangea cultivars are used, then they are easy to grow, but they lack strong stems and uniform, large inflorescences
Solution Approach 1:
The patent applies parameter changes by selecting and breeding Hydrangea plants with specific genetic parameters that result in stronger stems and more uniform, larger inflorescences. The cultivar 'Levana' was developed through planned breeding to achieve these specific phenotypic parameters, resolving the contradiction between ease of growth and structural strength.
2Ease of manufacture
If existing Hydrangea cultivars are used, then they are easy to grow, but they are susceptible to pathogens and pests
Solution Approach 1:
The patent applies the principle of selecting for disease resistance by developing a cultivar with inherent tolerance to pathogens and pests. The breeding program specifically selected plants that exhibited resistance traits, creating a cultivar that maintains ease of growth while being more resistant to harmful biological factors.
3Shape
If existing Hydrangea cultivars are used, then they are easy to grow, but they lack uniform and large inflorescences
Solution Approach 1:
The patent applies parameter changes by selecting and breeding Hydrangea plants with specific genetic parameters that result in more uniform and larger inflorescences. The cultivar 'Levana' was developed through planned breeding to achieve these specific phenotypic parameters, resolving the contradiction between ease of growth and inflorescence quality.
