Cherry Laurel JOPRU2 High Vigor Growth Rate and Foliage Color
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need for a new and distinct variety of cherry laurel plant (Prunus laurocerasus) that exhibits high vigor, growth rate, and specific foliage characteristics, which existing varieties do not adequately provide.
Innovation Solution
The development of the 'JOPRU2' variety, characterized by an obovate shape with a broad upright habit, high growth rate, and yellow-green to green foliage, achieved through open-pollination and subsequent vegetative propagation via softwood cuttings, ensuring reproduction true to type.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If existing cherry laurel varieties are used, then cultivation is straightforward, but they do not provide sufficient vigor, growth rate, or specific foliage characteristics
Solution Approach 1:
The patent applies parameter changes by selecting and propagating a plant variant with specific modified parameters (yellow-green to green foliage color, obovate shape, broad upright habit) that differ from standard cherry laurel varieties, thereby achieving both improved growth rate and distinct foliage characteristics
2Stability of the object's composition
If vegetative propagation is used to ensure true-to-type reproduction, then genetic consistency is maintained, but propagation time and effort increase
Solution Approach 1:
The patent employs preliminary action by performing vegetative propagation (softwood cutting) early in the plant's development cycle to establish genetically consistent stock plants, which then can be multiplied efficiently while maintaining true-to-type reproduction and reducing future propagation time
