Caladium Sizzle Compact Growth and Sunburn Tolerance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need for new Caladium cultivars with compact growth habits, attractive foliage, and exceptional container and landscape performance that can thrive under various environmental conditions while maintaining distinct characteristics.
Innovation Solution
The development of the Caladium cultivar 'Sizzle', which features a symmetrical, arching plant form with heart-shaped leaves having dark red to purple primary veins, netted purple secondary veins, and mottled undulate margins, differing from its parents in vein color, petiole attachment, and tuber surface characteristics, and exhibiting improved growth habits and sunburn tolerance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If Caladium cultivars are bred for compact growth habit and attractive foliage, then container and landscape performance is improved, but maintaining distinct characteristics across different environments becomes challenging
Solution Approach 1:
The patent applies parameter changes by selecting and propagating plants that maintain specific phenotypic parameters (leaf shape, vein color, growth habit) across varying environmental conditions. The cultivar 'Sizzle' was selected for maintaining its distinctive characteristics through at least nine generations of successive asexual propagations despite environmental variations in temperature, light intensity, water status, and fertilizer conditions.
2Reliability
If new cultivars are developed with improved growth habits and sunburn tolerance, then plant performance is enhanced, but development time and propagation stability must be maintained
Solution Approach 1:
The patent applies preliminary action by conducting extensive breeding work and selection processes before the cultivar is released. The cultivar was discovered and selected in 2004, and its distinctive characteristics have been maintained through at least nine generations of successive asexual propagations since then, ensuring stability before commercial release.
3Shape
If aroids are bred for numerous leaves and attractive foliage, then ornamental value is improved, but growth habit compactness may be compromised
Solution Approach 1:
The patent applies local quality by developing a cultivar with specific leaf characteristics (heart-shaped leaves with large rose center, dark red to purple primary veins, netted purple secondary veins, and mottled undulate margins) while maintaining compact overall growth habit. The leaf morphology is optimized locally without compromising the compact plant architecture.
