Osteospermum Cultivar DEL COM BW Heat Tolerance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing Osteospermum cultivars lack a compact growth habit with high heat tolerance and distinct inflorescence characteristics, particularly in comparison to 'Balserlabli', and have not been fully evaluated under various environmental conditions.
Innovation Solution
The new cultivar 'DEL COM BW' exhibits a small spoon daisy type inflorescence, freely flowering compact growth habit, magenta inflorescences with dark purple and violet undertones, and high heat tolerance, distinguished by its stable reproduction through asexual methods.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If existing Osteospermum cultivars are used, then they have established growth patterns, but they lack compact growth habit and high heat tolerance
Solution Approach 1:
The patent applies parameter changes by selecting and stabilizing specific genetic traits through asexual reproduction to achieve a compact growth habit (reduced plant spread and height) while simultaneously maintaining high heat tolerance. The cultivar 'DEL COM BW' exhibits these optimized parameters that differ from parent selections, resolving the contradiction between growth form and environmental adaptability.
2Quantity of substance
If existing Osteospermum cultivars are used, then they have established inflorescence characteristics, but they lack distinct inflorescence features and inflorescence density
Solution Approach 1:
The patent applies local quality by developing distinct inflorescence characteristics specific to certain regions of the plant. The cultivar 'DEL COM BW' produces multiple inflorescences per lateral branch with specific color properties (magenta with dark purple and violet undertones), creating localized quality differences that distinguish it from parent selections and enhance overall inflorescence density.
3Stability of the object's composition
If asexual reproduction is used to stabilize traits, then genetic consistency is achieved, but environmental adaptability may be reduced
Solution Approach 1:
The patent applies preliminary action by performing mass selection and open pollination under controlled conditions to pre-establish the desired genetic composition before asexual reproduction. The cultivar was discovered and selected through systematic observation of phenotypic expression under specific environmental conditions (temperature, daylength, light intensity), ensuring that the stabilized traits already possess inherent environmental adaptability.
