Echinacea Cultivar CATHARINA Peduncle Strength and Floret Durability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing Echinacea purpurea varieties, such as 'Magnus' and 'Pink Double Delight', suffer from drooping ray florets after harvesting, which limits their durability and commercial cut flower production potential.
Innovation Solution
The new cultivar 'CATHARINA' exhibits distinctive double dark pink flowers with strong peduncles and durable ray florets that resist drooping for at least 7 days post-harvest, achieved through vegetative reproduction and tissue culture stabilization.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Duration of action of stationary object
If existing Echinacea purpurea varieties (e.g., 'Magnus', 'Pink Double Delight') are used for cut flower production, then they can be harvested and transported, but the ray florets droop within a few days of harvesting, reducing durability
Solution Approach 1:
The patent applies parameter changes by selecting and propagating plants with specific genetic parameters that confer durability. The new cultivar 'CATHARINA' exhibits changed parameters in ray floret structure and physiological properties that enable them to resist drooping for at least 7 days post-harvest, compared to the parent variety 'Magnus' where ray florets droop within a few days.
2Stability of the object's composition
If the new cultivar 'CATHARINA' is developed through vegetative reproduction and tissue culture, then the unique features are stabilized and reproduced true to type, but the process requires multiple generations and controlled conditions
Solution Approach 1:
The patent applies copying through vegetative reproduction and tissue culture methods to produce identical copies of the new cultivar 'CATHARINA'. These asexual reproduction methods create genetic copies that maintain the unique characteristics (double dark pink flowers, strong peduncles, durable ray florets) true to type without the variation introduced by sexual reproduction.
Solution Approach 2:
The patent applies preliminary action by performing vegetative reproduction and tissue culture in controlled nursery conditions before the cultivar is released for commercial use. Multiple generations of tissue culture were conducted to stabilize the unique features before the cultivar was deemed ready for commercial propagation, ensuring consistency and reliability.
3Shape
If the new cultivar 'CATHARINA' produces double dark pink flowers with strong peduncles, then flower quality and commercial value are improved, but the plant requires specific environmental conditions to maintain phenotype consistency
Solution Approach 1:
The patent applies local quality by focusing on specific local characteristics of the plant that confer the desired traits. The new cultivar 'CATHARINA' exhibits local quality improvements in the flower morphology (double dark pink flowers), peduncle strength, and ray floret durability, while the overall plant architecture and foliage remain consistent with the parent variety 'Magnus'.
