JFS-red Tupelo Tree Narrow Growth Habit and Early Fall Color
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing Nyssa sylvatica cultivars lack desirable horticultural traits such as a narrow growth habit, upright branch angles, and early, bright fall color, which are essential for superior landscape use.
Innovation Solution
The development of the 'JFS-red' cultivar, characterized by a narrowly pyramidal shape, elongated oval leaves, and early peak fall color, achieved through asexual propagation methods like grafting and chip budding, which fixes the desired characteristics in successive generations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If conventional Nyssa sylvatica cultivars are used, then they have standard growth habits and fall color timing, but they lack narrow growth habit, upright branch angles, and early bright fall color
Solution Approach 1:
The patent applies parameter changes by selecting and propagating a specific cultivar ('JFS-red') with modified growth parameters including narrow habit, upright branch angles (40-60 degrees), and early fall color timing. These parameter changes distinguish the cultivar from standard Nyssa sylvatica and improve its suitability for landscape applications where space efficiency and aesthetic timing are critical
2Duration of action of moving object
If conventional Nyssa sylvatica cultivars are used, then they have standard fall color timing, but they lack early and bright fall color
Solution Approach 1:
The patent achieves early and bright fall color through parameter changes in the 'JFS-red' cultivar, which displays fall color 2-3 weeks earlier than standard cultivars with significantly brighter red intensity. This parameter modification allows landscapers to achieve earlier seasonal color impact and extended ornamental value
3Stability of the object's composition
If asexual propagation methods are used, then desired characteristics are fixed in successive generations, but propagation success requires multiple attempts
Solution Approach 1:
The patent employs copying through asexual propagation methods (grafting and chip budding) to replicate the exact genetic characteristics of the 'JFS-red' cultivar. While grafting success rates vary (60-80% in different trials), successful copies produce genetically identical plants that reliably inherit the narrow growth habit, upright branching, and early bright fall color, ensuring characteristic fixation across generations
