Hydrangea ILVOHPPRM Cultivar with Large Conical Panicles
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need for new Hydrangea varieties with large, vibrant panicles that age from greenish-white to pinkish-red, which are stable and reproduce true to type, as existing varieties may not meet these specific horticultural characteristics effectively.
Innovation Solution
The cultivar 'ILVOHPPRM' is developed through planned breeding, featuring large, conical-shaped panicles that transition from greenish-white to pinkish-red, with red stem color on new growth, achieved through asexual reproduction by softwood cuttings, showcasing unique and stable traits.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If existing Hydrangea varieties are used, then cultivation is straightforward, but the panicles are not large enough and do not age to vivid dark pink to red
Solution Approach 1:
The patent applies parameter changes by selecting and propagating plants with specific phenotypic parameters (large panicle size, conical shape, vivid color aging from greenish-white to dark pink to red) to create a cultivar that consistently exhibits these improved characteristics
Solution Approach 2:
The patent uses asexual reproduction through softwood cuttings to create genetic copies of the selected parent plant, ensuring that the unique traits of large panicles and vivid color aging are reproduced true to type in subsequent generations
2Reliability
If asexual reproduction is used to maintain trait stability, then true-to-type reproduction is achieved, but the process requires specific propagation techniques
Solution Approach 1:
The patent employs softwood cutting propagation to create genetic copies of the parent plant, ensuring true-to-type reproduction of the unique traits including large conical panicles and vivid color aging characteristics
3Quantity of substance
If panicles are made larger and denser, then visual appeal and flower production increase, but the plant requires more resources and space
Solution Approach 1:
The patent selects and propagates plants with enhanced panicle parameters (larger size, conical shape, denser flower distribution) to achieve increased visual appeal and flower production while maintaining manageable plant dimensions through controlled propagation
