Hydrangea Hybrida HMUPSI Compact Growth and Re-blooming
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need for a new Hydrangea cultivar that exhibits a unique combination of traits such as a mop-head inflorescence, semi-dwarf compact plant form, strong re-blooming habit, vibrant colored inflorescence, and sturdy stems capable of supporting large inflorescences, which are not adequately met by existing varieties.
Innovation Solution
The development of the Hydrangea hybrida cultivar 'HMUPSI' through open pollination breeding, characterized by its mop-head inflorescence, semi-dwarf compact growth, strong re-blooming habit, and deep sepal color, which distinguishes it from other commercial varieties like 'Robert' and 'Berner', and demonstrates improved performance in both container and garden settings.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of stationary object
If existing Hydrangea varieties are used, then they may have large inflorescences, but the plant size becomes too large for container performance
Solution Approach 1:
The invention segments the plant into distinct growth zones by controlling rootstock selection and pruning practices, allowing the inflorescence to develop to full size while the overall plant remains compact through strategic removal of lower branches and suckers
Solution Approach 2:
The patent applies local quality by selecting specific rootstocks that confer dwarfing characteristics to the lower plant portions while allowing the upper inflorescence-bearing portions to maintain large flower heads, creating a gradient of growth rates from base to apex
2Volume of stationary object
If existing Hydrangea varieties are used, then they may have large inflorescences, but the stems become weak and cannot support the large inflorescences
Solution Approach 1:
The patent applies preliminary action through proactive stem strengthening measures including selective pruning to promote robust cane development, application of stem hardening treatments, and timing of flowering bud formation to coincide with peak stem strength periods
Solution Approach 2:
The invention creates a composite structural system where the stem is reinforced through incorporation of lignin and cellulose enhancements via nutritional programs, creating a multi-layered stem structure with improved compressive and tensile strength to support large inflorescences
3Duration of action of moving object
If existing Hydrangea varieties are used, then they may have good initial flowering, but re-blooming performance is weak
Solution Approach 1:
The patent implements periodic action through scheduled fertilization programs that cycle between high-nitrogen formulations to promote vegetative growth and flowering and low-nitrogen formulations to encourage bud set and re-blooming, creating multiple flowering cycles throughout the growing season
Solution Approach 2:
The invention applies parameter changes by dynamically adjusting key growth parameters including photoperiod manipulation through supplemental lighting, temperature variations to induce flowering hormones, and nutritional parameter shifts to synchronize multiple flushes of flower production
