Variegated Cornus Gostmazam Cultivar with Coral Red Winter Stems
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need for a new cultivar of Cornus sericea that exhibits unique ornamental characteristics such as variegated foliage, vibrant winter stems, and vigorous growth habit, which are not present in existing cultivars like 'Cardinal' and 'Bailhalo'.
Innovation Solution
The development of the 'Gostmazam' cultivar, which features variegated foliage with green centers and gold to creamy white margins, bright coral red stems in winter, an upright and rounded plant habit, yellowish white flowers, and white-blue tinted fruit, achieved through asexual propagation using stem cuttings.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If asexual propagation using stem cuttings is employed, then stable characteristics are reproduced true to type in successive generations, but the time and effort required for propagation increases
Solution Approach 1:
The patent performs preliminary selection and identification of the desired variegated phenotype in the seedling stage (2009), then immediately proceeds with asexual propagation through stem cuttings. This preliminary action ensures that the correct genotype is captured before characteristics may vary or deteriorate, thereby maintaining stability while optimizing the propagation timeline.
2Illumination intensity
If variegated foliage with gold to creamy white margins is developed, then ornamental value is enhanced, but the plant's ability to photosynthesize efficiently may be reduced
Solution Approach 1:
The variegated foliage exhibits local quality variation with green centers (high chlorophyll content for photosynthesis) and gold to creamy white margins (reduced chlorophyll for ornamental effect). This spatial differentiation allows the plant to maintain photosynthetic efficiency in the green central regions while displaying desirable ornamental coloration in the marginal regions, thus resolving the contradiction between ornamental value and energy production.
