Hydrangea HIISLA51 Cultivar Stem Strength and Flower Longevity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need for new Hydrangea macrophylla cultivars with sturdy stems and attractive inflorescences that exhibit good post-production longevity, as existing varieties may lack strength and longevity in their floral displays.
Innovation Solution
The development of the 'HIISLA51' Hydrangea cultivar, resulting from a cross-pollination between proprietary selections of Hydrangea macrophylla, which exhibits upright and spreading growth, strong stems, freely branching habit, dark green leaves, large and dense mophead inflorescences with purplish-pink flowers, and improved post-production longevity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If existing Hydrangea varieties are used, then they may have moderate growth and flowering, but they lack stem strength and post-production longevity
Solution Approach 1:
The patent applies parameter changes by selecting and breeding for specific genetic traits that result in altered stem strength and flower longevity characteristics. The cross-pollination between parental lines with different traits produced offspring with optimized combinations of stem rigidity, vascular strength, and floral durability, directly addressing the contradiction between structural strength and post-production reliability.
2Volume of moving object
If larger inflorescences are developed, then floral attractiveness improves, but stem strength and support capacity may be compromised
Solution Approach 1:
The patent employs composite material principles by combining genetic traits from two different parental lines - one contributing to large inflorescence development and the other to strong stem structure. The resulting hybrid plant exhibits composite characteristics where the stem functions as a composite structure capable of supporting both the increased inflorescence weight and maintaining structural integrity, resolving the contradiction between floral volume and stem strength.
3Productivity
If vigorous growth is promoted, then plant size and flowering output increase, but post-production longevity may decrease
Solution Approach 1:
The patent applies local quality principles by differentiating the expression of growth traits in different parts of the plant. The plant exhibits vigorous vegetative growth and high flowering output in the productive phase, while simultaneously developing enhanced structural qualities in stems and flowers that extend post-production longevity. This localized optimization of different plant parts resolves the contradiction between productivity and duration.
