Cynodon dactylon CD08 Cultivar Dense Foliage and Stolon Branching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need for a new and distinct variety of Cynodon dactylon that offers improved foliage density, stolon branching, and drought tolerance suitable for lawn grass and sports fields, as existing varieties may lack these characteristics or be less effective in maintaining a dense canopy and vigorous growth.
Innovation Solution
The 'CD08' cultivar of Cynodon dactylon exhibits dark green leaf color, medium leaf blade width, dense foliage canopy, freely-branched stolons, short stolon internodes, vigorous stolon and rhizome growth, and low inflorescence occurrence, making it suitable for landscaping and sports fields.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If existing Cynodon dactylon varieties are used, then basic lawn grass functions are provided, but foliage density and stolon branching are insufficient
Solution Approach 1:
The patent applies parameter changes by selecting and propagating a seedling with specific genetic parameters that result in shorter stolon internodes and increased stolon branching. This natural variation was captured through asexual propagation to maintain the improved parameters of dense foliage and vigorous stolon growth while eliminating the trade-off present in existing varieties.
2Productivity
If Cynodon dactylon varieties with vigorous growth are selected, then productivity is improved, but stability of characteristics through propagation may be compromised
Solution Approach 1:
The patent applies copying through asexual propagation by stolon cutting and division, which creates genetically identical copies of the superior seedling. This method preserves the vigorous growth characteristics and dense foliage traits stably across multiple generations, eliminating the genetic variation that would occur with sexual reproduction while maintaining the improved productivity traits.
