Hydrangea Stramalyn Cultivar Black Stems Frost Resistance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing Hydrangea cultivars lack improved flower colors, black stem color, frost resistance, stem strength, and mold resistance, particularly against botrytis.
Innovation Solution
The development of a new Hydrangea cultivar 'Stramalyn' with pink flowers, black stems, enhanced frost resistance, and mold resistance, resulting from a breeding program combining breeding selection 533/8 and 'Venice Raven', exhibiting distinct characteristics through asexual propagation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If conventional Hydrangea cultivars are used, then green stem color is maintained, but black stem color is not achieved
Solution Approach 1:
The patent applies parameter changes by selecting and breeding plants with specific genetic traits that result in black stem color. The breeding program systematically changed the color parameter of the stem from green (conventional) to black (novel) through controlled crosses and selection of offspring with the desired pigmentation characteristics.
2Shape
If conventional Hydrangea cultivars are used, then standard flower colors are maintained, but improved flower colors are not achieved
Solution Approach 1:
The patent changes the flower color parameter by performing controlled crosses between parent plants with different color traits. The breeding program selected offspring exhibiting novel or improved flower colors, systematically altering the color parameter from standard to improved variations through genetic recombination and selection.
3Reliability
If conventional Hydrangea cultivars are used, then basic frost resistance is maintained, but enhanced frost resistance is not achieved
Solution Approach 1:
The patent changes the reliability parameter of frost resistance by breeding plants with genetic traits conferring enhanced cold tolerance. The breeding program selected and propagated offspring that demonstrated superior survival and growth under frost conditions, thereby improving the reliability parameter of environmental stress resistance.
4Strength
If conventional Hydrangea cultivars are used, then average stem strength is maintained, but enhanced stem strength is not achieved
Solution Approach 1:
The patent changes the strength parameter of the stem by selecting and breeding plants with genetic traits that produce stronger, more rigid stem structures. The breeding program measured and selected offspring with superior stem strength characteristics, thereby improving the mechanical strength parameter through genetic selection.
5Reliability
If conventional Hydrangea cultivars are used, then susceptibility to mold and botrytis is maintained, but mold resistance is not achieved
Solution Approach 1:
The patent changes the reliability parameter of mold resistance by breeding plants with genetic traits that confer resistance to botrytis and other molds. The breeding program selected offspring that demonstrated reduced susceptibility to fungal pathogens, thereby improving the resistance parameter against harmful biological factors.
