Caladium UF331 Sun Burn Tolerance and Tuber Yield
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current caladium cultivars lack a novel combination of foliar characteristics, particularly in lance-leaved varieties, which affects their performance in container forcing and landscape planting, and there is a need for improved tuber yield and leaf coloration patterns.
Innovation Solution
The development of the new Caladium×hortulanum variety 'UF331', which features large, dark green veins and white to pink interveinal areas, providing an attractive coloration pattern and improved performance in container forcing and landscape planting compared to other lance-leaved varieties.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If existing lance-leaved caladium cultivars are used, then the plant growth habit is compact, but the leaf coloration pattern is not novel and attracts sun burn
Solution Approach 1:
The patent applies local quality by creating distinct zones on the leaf blade with different color characteristics - dark green venation patterns in the central area versus lighter interveinal areas at the margins. This localized color differentiation provides sun burn protection in high-light areas while maintaining aesthetic appeal in shaded regions, resolving the contradiction between compact lance-leaved shape and sun burn tolerance.
2Productivity
If existing caladium cultivars are used, then the plant can be grown from tubers, but the tuber yield is insufficient for commercial use
Solution Approach 1:
The patent employs parameter changes by selecting and propagating tubers with specific size, shape, and weight characteristics that optimize yield. The cultivation method controls environmental parameters such as temperature, moisture, and fertilization to enhance tuber formation, thereby increasing both the quantity and quality of tubers produced per plant for commercial purposes.
3Adaptability or versatility
If existing lance-leaved varieties are used, then the plant has compact growth habit, but the performance in container forcing and landscape planting is inferior
Solution Approach 1:
The patent applies universality by developing a caladium cultivar with lance-leaved morphology that simultaneously excels in multiple applications - container forcing, landscape planting, and cut flower production. The plant's compact growth habit, attractive coloration pattern, and sun burn tolerance make it reliably suitable for diverse commercial uses, eliminating the need for separate cultivars for different purposes.
