Syringa SMNSPH Cultivar Compact Habit Remontant Flowering
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current Syringa plant cultivars lack compact, freely-flowering varieties with long remontant flowering habits and vibrant, fragrant purplish-pink flowers, which limits their garden performance and aesthetic appeal.
Innovation Solution
A new cultivar, 'SMNSPH', resulting from a breeding program, exhibits a compact, upright to spreading growth habit, freely branching with large, fragrant purplish-pink flowers that bloom remontantly and for an extended period, surpassing its parent and hybrid counterparts in flowering frequency and duration, and inflorescence density.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Duration of action of moving object
If conventional Syringa cultivars are used, then they have established growth patterns, but they lack compact size and long remontant flowering habits
Solution Approach 1:
The patent applies parameter changes by selecting and breeding plants with specific genetic parameters that control flowering duration and plant habit. The new cultivar 'SMNSPH' exhibits remontant flowering (multiple flowering periods) and compact mounding habit through selected genetic parameters that differ from conventional cultivars, achieving both extended flowering duration and desirable plant shape simultaneously
2Quantity of substance
If conventional Syringa cultivars are used, then they have established flower colors, but they lack vibrant purplish-pink colors with strong fragrance
Solution Approach 1:
The patent changes the chemical parameters of flower pigmentation to achieve vibrant purplish-pink colors. The new cultivar exhibits enhanced anthocyanin pigmentation with specific color values (RHS 65D upper surface, 65C lower surface) and strong fragrance characteristics, representing a deliberate parameter change in flower chemistry and morphology
3Volume of stationary object
If conventional Syringa cultivars are used, then they have standard inflorescence sizes, but they lack large dense inflorescences
Solution Approach 1:
The patent merges multiple desirable traits into a single cultivar: large inflorescence size (9 cm diameter), high flower density (200-250 flowers per inflorescence), and frequent remontant flowering. This combination of traits in 'SMNSPH' achieves both large volumetric inflorescences and high flowering productivity that exceeds conventional cultivars
4Shape
If conventional Syringa cultivars are used, then they have established growth rates, but they lack moderate vigor with compact form
Solution Approach 1:
The patent applies local quality by creating a cultivar with moderate vigor that produces compact mounding habit (50 cm height, 35 cm diameter) rather than uniform vigorous growth. The new cultivar exhibits localized control of growth parameters, achieving compactness in above-ground structure while maintaining healthy root systems and overall plant health for good garden performance
