Petlibluve Petunia Cultivar Trailing Habit and Veined Flower Traits
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need for a new and distinct cultivar of Petunia hybrida that exhibits a unique combination of trailing and spreading plant habit, freely branching and flowering, with light blue flowers and dark veins, which differs from existing cultivars in terms of plant height, flower size, and environmental adaptability.
Innovation Solution
The cultivar 'Petlibluve' is developed through planned breeding, combining the traits of proprietary selections 'A0987' and 'B4178', characterized by a mounded plant habit, medium-sized light blue flowers with dark veins, and good garden performance, achieved through asexual reproduction by terminal vegetative cuttings.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If terminal vegetative cuttings are used for asexual reproduction, then the unique features of the new Petunia are stable and reproduced true to type, but the propagation process requires specific environmental controls and time
Solution Approach 1:
The patent applies self-service by using terminal vegetative cuttings that naturally root and propagate the plant without requiring complex artificial intervention. The cuttings utilize the plant's own physiological mechanisms to reproduce true-to-type features, maintaining genetic stability while enabling relatively rapid propagation compared to seed methods.
2Adaptability or versatility
If the plant habit is made trailing and spreading, then the plant exhibits good garden performance and adaptability, but the plant structure becomes more complex
Solution Approach 1:
The patent applies dynamics by creating a plant habit that is trailing and spreading rather than rigid or upright. This dynamic growth pattern allows the plant to adapt to various garden conditions and container types while maintaining an organized, manageable structure through controlled branching and leaf arrangement.
3Shape
If the flowers are light blue with dark veins, then the flower coloration is attractive and unique, but the coloration requires specific genetic expression that may be sensitive to environmental conditions
Solution Approach 1:
The patent applies local quality by concentrating the dark veining specifically on the light blue petal surfaces rather than throughout the entire flower structure. This localized coloration pattern maintains aesthetic appeal while requiring less extreme environmental conditions for consistent expression compared to uniform dark coloring.
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 'Petlibluve' cultivar demonstrates stability in its unique features, offering improved garden performance and adaptability across varying environmental conditions, making it suitable for hanging baskets, window boxes, and landscape applications.
Implementation Method 1
Asexual reproduction of the new cultivar by terminal vegetative cuttings since August 2002, in Enkhuizen, Netherlands has shown that the unique features of this new Petunia are stable and reproduced true to type in successive generations.
