Poinsettia NPCW19282 Upright Triangular Form Propagation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need for new poinsettia varieties with distinct characteristics such as upright habit and triangular plant form that are reproducible through asexual propagation, as existing varieties may lack these traits or have limited propagation success.
Innovation Solution
The development of the new poinsettia variety 'NPCW19282', derived from crossing 'Prima Red' and 'CHRISTMAS BEAUTY Red', which exhibits an upright habit and triangular form, and is successfully propagated via vegetative apical cuttings, maintaining its characteristics through successive generations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If asexual propagation is performed to maintain variety characteristics, then genetic consistency is improved, but propagation success rate may be limited
Solution Approach 1:
The patent describes a self-service propagation system where the poinsettia plant automatically produces adventitious roots on apical cuttings without requiring external rooting hormones or treatments. The cutting itself provides all necessary components for successful propagation, with the plant's natural physiological processes enabling root formation and subsequent growth, thereby achieving both genetic consistency and high propagation success rate
2Shape
If upright habit and triangular form are selected as distinguishing characteristics, then aesthetic value is improved, but breeding complexity increases
Solution Approach 1:
The patent specifically selects for asymmetric triangular plant form as a distinguishing characteristic of the new variety. This asymmetric shape, combined with the upright habit, creates a distinctive aesthetic appearance that differentiates the variety while being achievable through conventional breeding selection processes
Solution Approach 2:
The patent applies local quality by selecting for specific directional growth patterns in different parts of the plant. The upright habit refers to the overall vertical growth orientation of the plant, while the triangular form describes the specific spatial arrangement of branches and foliage, creating a structured three-dimensional form that is achieved through targeted selection of local growth characteristics
3Productivity
If free branching rooting habit is encouraged, then propagation efficiency is improved, but plant structure control becomes more difficult
Solution Approach 1:
The patent describes a dynamic plant structure where the poinsettia exhibits free branching rooting habit that allows flexible adaptation to propagation conditions. The plant can dynamically adjust its branching pattern and root development based on environmental cues and propagation methodology, enabling efficient propagation while maintaining the ability to develop a controlled triangular form through proper cultivation practices
