Dracaena KKDR201205 Variegated Foliage Cultivar
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need for a distinct and stable cultivar of Dracaena reflexa with unique foliage variegation and larger leaves, as existing cultivars lack these characteristics, and current varieties do not exhibit the desired variegation patterns or leaf size.
Innovation Solution
The cultivar 'KKDR201205' is a naturally occurring mutation of Dracaena reflexa, characterized by its distinctive foliage variegation and larger leaves, which are stable and reproduce true to type through asexual reproduction, maintaining its unique traits under varying environmental conditions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If existing Dracaena reflexa cultivars are used, then they are available for cultivation, but they lack distinctive foliage variegation and larger leaves
Solution Approach 1:
The patent applies parameter changes by selecting and propagating a natural mutant of Dracaena reflexa that exhibits altered foliar characteristics - specifically yellow-green variegation patterns and increased leaf size - thereby creating a new cultivar with modified physical parameters that distinguish it from existing green-leafed cultivars
2Shape
If a naturally occurring mutation is selected, then unique foliage characteristics are achieved, but stability of traits must be verified through multiple generations
Solution Approach 1:
The patent applies preliminary action by conducting stability tests across three generations of vegetative propagation before releasing the cultivar, ensuring that the unique variegation traits are heritable and stable, thereby preventing future variability and reducing long-term maintenance time
3Productivity
If vegetative cuttings are used for propagation, then the cultivar can be reproduced, but the process requires multiple generations to establish stability
Solution Approach 1:
The patent applies self-service by utilizing vegetative propagation through stem cuttings, which allows the plant to reproduce itself asexually, maintaining the exact genetic characteristics of the parent plant and enabling rapid multiplication without the need for sexual reproduction and associated genetic recombination
