Hydrangea Cultivar Stem Strength and Early Flowering
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing Hydrangea macrophylla cultivars lack strong stems, early flowering response, and attractive leaf and flower coloration, which are desirable traits for container-type plants.
Innovation Solution
A new cultivar, 'SCHROLL124-09-01', developed through planned breeding, exhibiting compact and upright growth, strong stems, freely branching habit, large mophead-type inflorescences with pink-colored sterile flowers, and extended flowering period, resulting from a cross-pollination between proprietary selections of Hydrangea macrophylla.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If conventional Hydrangea macrophylla cultivars are used, then basic growth is maintained, but stem strength is insufficient
Solution Approach 1:
The patent applies parameter changes by selecting and breeding plants with specific genetic parameters that result in stronger stems. The new cultivar 'SCHROLL124-09-01' exhibits stem strength that exceeds conventional cultivars, achieved through controlled cross-pollination and selection of parental plants with desirable traits, thereby changing the genetic parameters of the offspring to improve structural integrity.
2Speed
If conventional Hydrangea macrophylla cultivars are used, then basic flowering is achieved, but flowering response time is delayed
Solution Approach 1:
The patent applies preliminary action by conducting controlled cross-pollination during spring 2009 to pre-establish genetic traits that promote early flowering. The parental selections were specifically chosen and crossed in advance to produce progeny with accelerated flowering response, allowing the new cultivar to flower earlier than conventional varieties when grown under similar conditions.
3Ease of manufacture
If conventional Hydrangea macrophylla cultivars are used, then basic coloration is present, but leaf and flower coloration attractiveness is insufficient
Solution Approach 1:
The patent applies local quality by enhancing coloration specifically in certain parts of the plant - particularly the leaves and flowers - through selective breeding. The new cultivar exhibits improved coloration quality in its foliage and inflorescences compared to conventional cultivars, achieved by focusing breeding efforts on selecting parental plants with superior color traits and propagating these specific qualities in the offspring.
4Area of moving object
If conventional Hydrangea macrophylla cultivars are used, then basic inflorescence size is achieved, but inflorescence size is insufficient
Solution Approach 1:
The patent applies merging by combining desirable traits from two different parental selections through controlled cross-pollination. The breeding program merged the traits of early flowering and strong stems from one parent with attractive coloration and vigorous growth from the other, resulting in a new cultivar that exhibits larger inflorescences along with the other improved characteristics, thereby achieving multiple goals through a single breeding operation.
5Duration of action of stationary object
If conventional Hydrangea macrophylla cultivars are used, then basic shelf-life is maintained, but postproduction longevity is insufficient
Solution Approach 1:
The patent applies self-service by breeding plants with inherent traits that enable them to maintain their quality and longevity without requiring excessive external intervention. The new cultivar 'SCHROLL124-09-01' exhibits extended postproduction longevity and shelf-life through its genetically determined resistance to deterioration, allowing the plants to maintain commercial quality for longer periods under standard storage and display conditions, thereby improving commercial viability.
