Ligustrum sinensis Dwarf Variety Trait Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need for a distinct and stable Ligustrum sinensis variety that differs from existing varieties in leaf size, density, and growth habit, with improved characteristics for horticultural applications.
Innovation Solution
The 'Green Global' variety of Ligustrum sinensis, discovered through natural mutation and asexually reproduced, exhibits smaller leaves and a dwarf growth habit, retaining its characteristics through successive propagations and field testing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If natural mutation is utilized to create a new variety, then unique characteristics (smaller leaves, dwarf growth habit) are achieved, but stability and consistency of these traits across propagations must be verified
Solution Approach 1:
The patent utilizes asexual reproduction through cuttings to create identical copies of the mutated plant, ensuring that the unique characteristics (smaller leaves, dwarf growth habit) are consistently replicated across multiple propagations without genetic variation, thus verifying stability and consistency
2Shape
If leaf size is reduced to create a dwarf variety, then ornamental value and distinctiveness are improved, but overall plant vigor and growth rate may be reduced
Solution Approach 1:
The patent describes a natural mutation that specifically altered the leaf size parameter and growth habit parameters of Ligustrum sinensis, creating a dwarf variety with smaller leaves (0.5-1.5 cm length) and reduced internode length, while maintaining other physiological functions
