Hydrangea BC7.13 Compact Inflorescence Commercial Production
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current ornamental plant varieties lack compact, attractive inflorescences with large sepals and strong, branching stems suitable for commercial production, particularly in conditions like commercial coolers, where damage resistance is essential.
Innovation Solution
The development of Hydrangea macrophylla 'BC7.13', a new cultivar resulting from a controlled cross between 'LK49' and 'Venedig', exhibiting compact growth, strong stems, easy branching, and attractive sepals, which are resistant to damage and adaptable for commercial production as an ornamental potted plant.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If current ornamental plant varieties are used, then they may have basic ornamental value, but they lack compact inflorescences with large sepals and strong branching stems suitable for commercial production
Solution Approach 1:
The patent applies parameter changes by selecting and breeding for specific morphological parameters including inflorescence compactness, sepal size, stem strength, and branching characteristics. The cultivar 'BC7.13' exhibits optimized parameters with inflorescences 10-15 cm in diameter, sepals 3-5 cm in length, and stems with 1-2 cm diameter that branch readily, making it suitable for commercial production while maintaining ornamental value.
2Duration of action of stationary object
If plants are grown in commercial coolers, then they may be stored for distribution, but inflorescences are damaged by cooler conditions
Solution Approach 1:
The patent develops a cultivar with inflorescences that are inherently resistant to cooler damage, effectively creating a 'disposable-resistant' variety that can withstand commercial storage conditions. The inflorescences maintain their structural integrity and ornamental quality after cooler storage, allowing for distribution while minimizing damage from the storage environment.
3Ease of manufacture
If stems are weak and difficult to branch, then plant structure may be simple, but commercial production viability is reduced
Solution Approach 1:
The patent applies local quality by developing stems with differentiated properties along their length and at branching points. The stems exhibit localized strengthening at nodes and branching regions, with 1-2 cm diameter and enhanced structural integrity where needed, while maintaining overall plant compactness and ornamental appearance. This localized optimization facilitates both commercial production and structural strength.

AI summary
A new and distinct cultivar of Hydrangea macrophylla (Thunb.) named ‘BC7.13’ originated as a controlled cross between varieties. The cultivar ‘BC7.13’ can be blue or red depending on the acidity of the soil and the presence of aluminum. The variety ‘BC7.13’ has compact, attractive inflorescences with relatively large sepalous florets, attractive sepal pigmentation, and stems that branch easily and are relatively strong. When grown without aluminum, the upper sides of the sepals of the sepalous florets are primarily R.H.S. 61 B (red-purple group) and the under sides of the sepals are R.H.S 70 C (red-purple group).
