Sarcococca PMOORE03 Cultivar Container Growth and Sun Tolerance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Sarcococca hookeriana varieties typically do not thrive when container-grown and struggle with full sun conditions, lacking desirable traits like fragrant flowers and dark green glossy foliage.
Innovation Solution
The development of 'PMOORE03', an evergreen shrub cultivar resulting from controlled breeding, exhibiting dark green glossy foliage, fragrant reddish-pink flowers, and moderate growth rate, suitable for container growth and varying light conditions, achieved through asexual propagation by semi-ripe stem cuttings.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If Sarcococca hookeriana varieties are grown in containers, then portability and space efficiency are improved, but plant health and growth performance deteriorate
Solution Approach 1:
The patent applies parameter changes by developing a cultivar with modified physiological characteristics that enable container growth. 'PMOORE03' exhibits altered growth patterns, root architecture, and resource utilization parameters that allow thriving in confined container environments, directly resolving the contradiction between container volume and plant health reliability
2Illumination intensity
If Sarcococca hookeriana varieties are exposed to full sun, then light availability for photosynthesis is improved, but plant tolerance and survival deteriorate
Solution Approach 1:
The cultivar 'PMOORE03' exhibits changed physiological parameters including enhanced photosynthetic efficiency, improved water use efficiency, and modified leaf morphology that enable tolerance to full sun conditions. This resolves the contradiction by allowing the plant to utilize high illumination intensity without suffering harmful effects
3Stability of the object's composition
If typical Sarcococca hookeriana varieties are bred for traditional growth habits, then species authenticity is preserved, but ornamental value and fragrance characteristics deteriorate
Solution Approach 1:
The patent merges desirable traits from different Sarcococca sources to create 'PMOORE03', combining species authenticity with enhanced ornamental characteristics including fragrant flowers and dark green glossy foliage. This merging resolves the contradiction by integrating multiple positive attributes while maintaining species identity
4Stability of the object's composition
If asexual propagation by semi-ripe stem cuttings is used, then genetic stability and true-to-type reproduction are improved, but propagation time and labor requirements increase
Solution Approach 1:
The patent employs preliminary action by selecting and propagating during the semi-ripe stage, which is optimally timed to balance root development speed with genetic stability. This timing allows cuttings to have sufficient maturity for stable propagation while not being so mature that propagation time is excessive, thus resolving the contradiction between genetic stability and propagation time
