Hydrangea SAXDIFIOROS Breeding for Stronger Stems and Durable Inflorescences
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing Hydrangea cultivars lack strong stems and long-lasting inflorescences with attractive coloration, limiting their durability and visual appeal.
Innovation Solution
A new cultivar, 'SAXDIFIOROS', resulting from cross-pollination between a proprietary Hydrangea macrophylla breeding selection and Hydrangea macrophylla 'Semperflorens', exhibiting bright pink inflorescences, dark green foliage, and stronger stems, achieved through asexual reproduction by softwood cuttings.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If conventional Hydrangea cultivars are used, then they have basic growth characteristics, but they lack strong stems and long-lasting inflorescences with attractive coloration
Solution Approach 1:
The patent applies parameter changes by selecting and breeding plants with specific genetic traits that result in enhanced stem strength and improved inflorescence durability. The new cultivar 'SAXDIFIOROS' exhibits these improved parameters through controlled cross-pollination and selection of parent plants with desirable characteristics.
Solution Approach 2:
The patent employs composite materials in the sense of combining genetic traits from two different parent cultivars to create a new hybrid with superior properties. The female parent contributes certain characteristics while the male parent contributes others, resulting in a composite genetic structure that delivers both strong stems and durable, colorful inflorescences.
2Duration of action of stationary object
If conventional Hydrangea cultivars are used, then they have basic coloration, but they lack long-lasting inflorescences with attractive coloration
Solution Approach 1:
The patent applies preliminary action by pre-selecting parent plants with specific desirable traits before cross-pollination. The female parent is chosen for characteristics that will contribute to inflorescence longevity and coloration, while the male parent is selected to complement these traits, thereby preparing the genetic foundation in advance to achieve the desired outcome.
Solution Approach 2:
The patent employs feedback mechanisms in the breeding process by observing and evaluating the characteristics of progeny plants, then using this information to select the best individuals for further propagation. This iterative selection process ensures that plants with the desired combination of long-lasting and attractively colored inflorescences are identified and maintained.
3Strength
If existing cultivars like ENDLESS SUMMER 'Bailmer' are used, then they have pink inflorescences, but they lack the stronger stems and larger sterile floret sepals of 'SAXDIFIOROS'
Solution Approach 1:
The patent applies parameter changes by establishing specific quantitative and qualitative thresholds for stem strength and inflorescence characteristics that distinguish the new cultivar from existing ones. These changed parameters include not only stem strength but also the size of sterile floret sepals and the consistency of pink coloration, creating a more precisely defined cultivar standard.
