Gentiana makinoi Cultivar Magic Purple Stem Strength and Flower Color
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need for a new cultivar of Gentiana makinoi that exhibits distinct characteristics such as deeper violet-blue flowers, dark black-purple stems, and a vigorous growth habit, which are not present in existing varieties like 'Royal Blue' and 'Marsha'.
Innovation Solution
The 'Magic Purple' cultivar, discovered as a chance seedling, features large, deep violet-blue flowers, dark black-purple stems, and a compact, uniformly tall growth habit, suitable for landscape use and cut flower arrangements, achieved through asexual reproduction by in vitro propagation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional Gentiana varieties like 'Royal Blue' are used, then the plants are easier to propagate and maintain, but they lack the distinctive deep violet-blue flower color and dark black-purple stems that characterize the new cultivar
Solution Approach 1:
The patent employs in vitro propagation to create exact genetic copies of the 'Magic Purple' cultivar. This tissue culture method produces clones that faithfully reproduce the distinctive deep violet-blue flower color and dark black-purple stem characteristics, ensuring both reliability of trait reproduction and ease of large-scale propagation.
2Productivity
If Gentiana varieties with vigorous growth habits are selected, then the plants produce more biomass and larger flowers, but they require more resources and space for cultivation
Solution Approach 1:
The patent describes a cultivar with optimized growth parameters that achieve vigorous productivity while reducing resource demands. The 'Magic Purple' Gentiana exhibits uniform stem height (about 115 cm), compact clump-forming habit, and efficient resource utilization, representing an optimization of growth parameters that balances productivity with resource efficiency.
3Shape
If Gentiana varieties are bred for uniform stem height and compact growth habit, then they are more suitable for landscape use and cut flower arrangements, but they may reduce genetic diversity and adaptability
Solution Approach 1:
The patent describes a cultivar with specific localized traits optimized for ornamental purposes: uniform stem height (about 115 cm), compact clump-forming habit, and consistent flowering characteristics. These localized quality improvements in specific plant attributes achieve the desired landscape and cut flower qualities while the in vitro propagation maintains genetic consistency of these desirable traits.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The 'Magic Purple' cultivar offers a unique combination of traits, including thicker, darker stems and more intense flower color, making it suitable for landscape use and cut flower arrangements, with stable reproduction and high growth vigor, while maintaining cold hardiness and disease resistance.
Implementation Method 1
Asexual reproduction of the new cultivar was first accomplished by in vitro propagation under the direction of the inventor in Rijswijk, The Netherlands in 2005. It has been determined that the characteristics of the new cultivar are stable and are reproduced true to type in successive generations.
