Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current Hydrangea macrophylla cultivars lack compact plant habits and floriferous blooming with double sterile flowers, limiting their landscape appeal and versatility.
Innovation Solution
Development of the new cultivar 'Hort 09-012-05', which exhibits a compact and uniform plant habit, double sterile white star-shaped flowers with pointed tips, achieved through controlled breeding and asexual propagation by stem cuttings, combining traits of compact growth and abundant flowering.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If traditional Hydrangea macrophylla cultivars are used, then they have established breeding history, but they lack compact plant habits and floriferous blooming with double sterile flowers
Solution Approach 1:
The invention applies parameter changes by selecting and breeding for specific morphological parameters including compact plant habit, double sterile flowers with numerous sepals, and star-shaped flower morphology. This transforms traditional hydrangea parameters to achieve the desired compact form and floriferous characteristics
Solution Approach 2:
The new cultivar achieves multi-functionality by combining compact plant habit suitable for container gardening with abundant double sterile flowers for ornamental value, making it adaptable to multiple landscape applications including borders, mass plantings, and container displays
2Adaptability or versatility
If self-pollination breeding method is used to develop new cultivars, then new traits can be obtained, but breeding time and generation selection period are extended
Solution Approach 1:
The invention applies preliminary action by performing controlled self-pollination on selected parent plants before mass propagation, allowing the desired traits to be established in the breeding stage. This preliminary selection and pollination approach streamlines the subsequent propagation phase
Solution Approach 2:
The invention uses asexual propagation by stem cuttings to create exact copies of the selected mutant plant, preserving the unique combination of compact habit and double sterile flowers without requiring further generations of sexual breeding
3Stability of the object's composition
If asexual propagation by stem cuttings is used, then genetic stability and true-to-type reproduction are achieved, but propagation complexity and technical requirements increase
Solution Approach 1:
The invention applies self-service by utilizing the plant's own stem tissue for propagation, where stem cuttings from the parent plant naturally root to produce genetically identical offspring. This self-propagation method eliminates the need for complex tissue culture facilities or external grafting materials
