Geum TNGEUPP Repeat Blooming and Compact Growth
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing Geum cultivars like 'Cosmopolitan' and 'Mai Tai' are primarily spring-blooming with less compact and shorter flowering stems, lacking the desired yellow and rose-red flower color, and reblooming characteristics.
Innovation Solution
The development of a new Geum cultivar 'TNGEUPP' with light yellow flowers having rose-red edges and tints, double flowers, dense foliage, compact mounding habit, and repeat blooming throughout the summer, achieved through asexual propagation using tissue culture techniques.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Duration of action of stationary object
If traditional Geum cultivars like 'Cosmopolitan' and 'Mai Tai' are used, then spring blooming is achieved, but repeat blooming throughout the summer is not obtained
Solution Approach 1:
The cultivar 'TNGEUPP' exhibits dynamic blooming behavior, transitioning from primary spring blooming to sporadic repeat blooming throughout the summer. This dynamic characteristic allows the plant to adapt its flowering pattern to seasonal changes, achieving both spring blooming and extended summer reblooming that was not present in traditional cultivars.
2Shape
If traditional Geum cultivars are used, then flowering stems are longer, but compact growth habit is not achieved
Solution Approach 1:
The cultivar 'TNGEUPP' exhibits localized compact growth characteristics throughout the entire plant structure. The growth habit is uniformly compact with dense foliage and shortened internodes, creating a mounding form that maintains compactness while supporting the flowering stems, rather than only affecting specific parts of the plant.
3Shape
If traditional Geum cultivars are used, then flower colors are limited, but yellow with rose-red edges and peach tone is not achieved
Solution Approach 1:
The cultivar 'TNGEUPP' displays complex color changes and interactions, producing light yellow petals with rose-red edges and peach tones. The coloration includes gradient transitions from yellow centers to rose-red margins, with older flowers developing deeper rose-red tints, creating a dynamic color display that evolves throughout the blooming period.
