Hydrangea Cultivar SCHROLL122-11-01a Compact Habit and Stem Strength
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing Hydrangea macrophylla cultivars lack compact, upright growth habits with strong stems and attractive flower coloration, particularly in container-type plants, and have limited branching and flowering periods.
Innovation Solution
The development of the new Hydrangea cultivar 'SCHROLL122-11-01a' through cross-pollination, exhibiting a compact, upright, and freely branching habit with strong stems, dark green leaves, and mophead-type inflorescences with light red-purple flowers that turn violet blue when treated with aluminum sulfate, offering a longer flowering period and improved post-production quality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If existing Hydrangea macrophylla cultivars are used, then they have moderate growth vigor, but they lack compact upright habit and strong stems
Solution Approach 1:
The patent applies parameter changes by selecting and breeding for specific morphological parameters including compact upright plant habit, strong stem strength, and freely branching characteristics. The cultivar 'SCHROLL122-11-01a' exhibits these improved parameters through controlled cross-pollination and selection processes, transforming the physical characteristics of Hydrangea plants to achieve both compact shape and stem strength simultaneously
2Duration of action of moving object
If existing Hydrangea macrophylla cultivars are used, then they have average flowering period, but they lack long flowering period and attractive coloration
Solution Approach 1:
The patent changes the flowering parameters by breeding for extended flowering duration and attractive coloration. The cultivar 'SCHROLL122-11-01a' displays light red-purple sterile flowers with violet blue coloration when treated with aluminum sulfate, along with a prolonged flowering period. This is achieved through selective breeding that modifies both the temporal duration and visual quality parameters of flowering
Solution Approach 2:
The patent explicitly utilizes color changes as a key feature, where the sterile flowers exhibit light red-purple coloration that transforms to violet blue when treated with aluminum sulfate. This color transformation capability is bred into the cultivar, providing both aesthetic value and a distinctive characteristic that differentiates it from existing cultivars
3Productivity
If existing Hydrangea macrophylla cultivars are used, then they have limited branching habit, but they lack freely branching habit with strong lateral branches
Solution Approach 1:
The patent improves branching parameters by selecting for freely branching habit combined with strong lateral branches. The cultivar 'SCHROLL122-11-01a' exhibits multiple lateral branches per plant with enhanced strength, representing a change in the structural and proliferative parameters of the plant architecture through selective breeding
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The new cultivar 'SCHROLL122-11-01a' provides a compact, vigorous, and freely branching plant with enhanced stem strength and flower color, extending the flowering period and maintaining quality, distinguishing it from parent and comparable cultivars.
Implementation Method 1
mophead-type inflorescences with light red purple-colored sterile flowers; when 'blued', that is, treated with aluminum sulfate, sterile flowers are violet blue in color
