Sedum Touchdown Teak Cultivar Asexual Propagation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current Sedum telephium cultivars lack desirable traits such as dark red to dark red brown foliage, strong dark red stems, multiple crowns, and rose pink flowers, which are not adequately addressed in existing varieties like Sedum 'Desert Black', and there is a need for a compact, vigorous, and aesthetically appealing cultivar with improved habit and flower color.
Innovation Solution
The development of a new cultivar, 'Touchdown Teak', which features dark red brown oval leaves, strong dark red stems, multiple crowns, rose pink flowers, and a medium short upright habit, achieved through asexual propagation using division and tissue culture techniques, resulting in consistent and true-to-form progeny.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If existing Sedum telephium cultivars like Sedum 'Desert Black' are used, then they provide basic foliage color, but they lack desirable traits such as dark red to dark red brown foliage, strong dark red stems, multiple crowns, and rose pink flowers
Solution Approach 1:
The patent uses asexual propagation methods (division and tissue culture) to create exact genetic copies of the selected parent plant that possesses all desired traits. This ensures that the progeny plants are true-to-form and consistently exhibit dark red brown foliage, strong dark red stems, multiple crowns, and rose pink flowers, resolving the reliability issue while maintaining aesthetic appeal
2Manufacturing precision
If asexual propagation by division and tissue culture is used, then consistent and true-to-form progeny are achieved, but the process requires standard micropropagation techniques and controlled conditions
Solution Approach 1:
The propagation process is divided into two distinct methods: division (separating the plant into sections with crowns and roots) and tissue culture (micropropagation from shoot tips or nodal segments). This segmentation allows breeders to choose the appropriate method based on available resources while both methods reliably produce true-to-form progeny, balancing precision with manageable complexity
