Eastern Redbud JN3 Chip Budding Propagation and Foliage Traits

Resolve Bottlenecks,
Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing Eastern Redbud tree cultivars lack distinctive golden orange new growth and speckled lime green mature foliage with a wavy, rugose dark green margin, and are not as hardy in drought conditions, with popular cultivars like 'Hearts of Gold' showing reduced performance during severe drought and heat.

Innovation Solution

A new variety of Eastern Redbud tree, 'JN3', exhibiting golden orange new growth and speckled lime green mature foliage with a wavy, rugose dark green margin, propagated by chip budding onto seedling rootstock, demonstrating improved hardiness and durability in varying climates and soil conditions.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Shape

If existing Eastern Redbud cultivars are grown, then they provide typical green foliage, but they lack distinctive golden orange new growth and speckled lime green mature foliage with wavy rugose dark green margin

Engineering Contradiction:

Improveleaf margin shapeVSAvoidfoliage distinctiveness

Core Design Contradiction:

ShapeVSEase of manufacture

Solution Approach 1:

The patent applies local quality by creating distinct variations in different parts of the leaf: the margin has a wavy rugose dark green appearance while the center maintains speckled lime green coloration. This localized differentiation of leaf properties creates the distinctive foliage character that sets 'JN3' apart from conventional redbuds with uniform green leaves

Inventive Principle:

Principle #3Local quality

2Reliability

If popular cultivars like 'Hearts of Gold' are planted, then they provide yellow foliage, but they show reduced performance and foliage burn during severe drought and heat conditions

Engineering Contradiction:

Improvedrought toleranceVSAvoidfoliage burn

Core Design Contradiction:

ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The patent embodies this principle by converting the potential harm of drought and heat stress into a beneficial demonstration of superior adaptability. The 'JN3' cultivar's distinctive wavy rugose margin and speckled lime green foliage not only provide aesthetic value but also serve as indicators of enhanced physiological resilience, allowing the tree to thrive in adverse conditions where other cultivars fail

Inventive Principle:

Principle #22Blessing in disguise (Convert harm into benefit)

3Stability of the object's composition

If Eastern Redbud trees are propagated by chip budding onto seedling rootstock, then the characteristics are firmly fixed, but the propagation process requires precise timing and technique

Engineering Contradiction:

Improvecharacteristic fixationVSAvoidpropagation difficulty

Core Design Contradiction:

Stability of the object's compositionVSEase of manufacture

Solution Approach 1:

The patent applies preliminary action by performing chip budding during the summer months when the rootstock and scion are in optimal physiological condition for union. This timing preparation ensures that the distinctive foliage characteristics are firmly established early in the tree's development, allowing the propagated trees to maintain true-to-type characteristics throughout their lifecycle

Inventive Principle:

Principle #10Preliminary action
