PAL42 St. Augustine Grass Cultivar Fast Growth
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing Stenotaphrum secundatum cultivars lack desirable traits such as fast growth rate, greater internodal spacing of stolons, and improved disease resistance, which are essential for creating a high-quality, low-maintenance turf grass with enhanced environmental tolerance.
Innovation Solution
The development of the 'PAL42' cultivar, which results from an open-pollination breeding program, exhibits a combination of fast growth rate, long stolons, and improved disease resistance, achieved through asexual propagation methods like division of rhizomes, maintaining stable and true-to-type characteristics.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If conventional Stenotaphrum secundatum cultivars are used, then production and maintenance costs are lower, but growth rate is slow and internodal spacing is insufficient
Solution Approach 1:
The patent applies parameter changes by selectively breeding plants with specific genetic traits that result in altered growth parameters. The 'PAL42' cultivar exhibits changed parameters including faster growth rate and greater internodal spacing compared to conventional cultivars, achieved through open-pollination breeding programs that selected for these specific characteristics.
2Reliability
If conventional Stenotaphrum secundatum cultivars are used, then disease resistance is limited, but environmental tolerance is reduced
Solution Approach 1:
The patent applies composite materials principle by creating a cultivar that combines multiple desirable traits into a single genetic composition. The 'PAL42' cultivar integrates disease resistance, environmental tolerance, fast growth rate, and improved internodal spacing into a composite genetic structure through selective breeding, achieving a combination of traits not found in conventional single-trait cultivars.
3Shape
If stolons are shortened for dense turf, then turf density increases, but aesthetic quality and coverage reduce
Solution Approach 1:
The patent applies local quality principle by optimizing stolon characteristics at different locations and scales. The 'PAL42' cultivar exhibits greater internodal spacing that creates an aesthetically pleasing open turf structure while maintaining adequate density through other growth mechanisms. This local optimization of stolon morphology achieves both visual appeal and functional turf performance.
