Hydrangea macrophylla BCHY-14.003 Pigmentation Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current ornamental Hydrangea macrophylla cultivars face challenges in maintaining long-lasting, attractive inflorescence pigmentation and compact growth habits suitable for small pots, as existing varieties often experience color bleeding and stem greening with age.
Innovation Solution
The new cultivar Hydrangea macrophylla 'BCHY-14.003' is developed through a controlled cross, featuring compact growth, long-lasting white pigmentation on sepals that resists bleeding and greening, with a stable combination of characteristics suitable for 4-inch pots, achieved through asexual reproduction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Duration of action of stationary object
If existing Hydrangea cultivars are grown to maintain inflorescence pigmentation, then the pigmentation is initially attractive, but the color bleeds toward the center and stems turn green as the inflorescence ages
Solution Approach 1:
The patent applies parameter changes by developing a new cultivar with genetically altered pigmentation properties. The cultivar 'BCHY-14.003' exhibits modified pigment stability parameters, maintaining the white group color (R.H.S. 155 D) on the upper sides of sepals and resisting the bleeding effect that occurs in existing cultivars. This genetic parameter change enables the pigmentation to remain stable for 5-6 weeks under controlled temperature conditions (62°F night, 70°F day), directly resolving the contradiction between duration and stability.
2Volume of stationary object
If Hydrangea cultivars are bred for large inflorescences, then the floral display is more impressive, but the plant size becomes too large for compact pot cultivation and transport
Solution Approach 1:
The patent applies local quality by creating a cultivar with differentiated growth characteristics in different plant regions. The cultivar 'BCHY-14.003' exhibits compact overall plant habit suitable for 4-inch pots while maintaining relatively large inflorescences (50-65 mm diameter) as a local feature. This localized optimization allows the plant to adapt to container cultivation constraints while preserving the desirable large-flowered appearance, resolving the contradiction between inflorescence size and pot adaptability.
3Adaptability or versatility
If Hydrangea cultivars are developed with compact growth habit for small pots, then the plant is suitable for commercial transport, but the inflorescence size and visual impact are reduced
Solution Approach 1:
The patent applies local quality by creating a cultivar with differentiated growth characteristics in different plant regions. The cultivar 'BCHY-14.003' exhibits compact overall plant habit suitable for 4-inch pots while maintaining relatively large inflorescences (50-65 mm diameter) as a local feature. This localized optimization allows the plant to adapt to container cultivation constraints while preserving the desirable large-flowered appearance, resolving the contradiction between inflorescence size and pot adaptability.
