Solution Overview

Problem

Current Limonium sinuatum cultivars lack vigorous and freely flowering traits with long, straight stems, and have limitations in growth habit, flower arrangement, and post-production longevity.

Innovation Solution

The development of a new cultivar, 'Esm Julio', resulting from a breeding program that combines the desirable traits of erect, strong flowering stems, vigorous growth, violet blue-colored flowers, and extended post-production longevity, achieved through asexual reproduction by cuttings in a controlled greenhouse environment.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Strength

If conventional Limonium sinuatum cultivars are used, then basic flowering is achieved, but vigorous growth and long straight stems are not obtained

Engineering Contradiction:

Improvestem strength and straightnessVSAvoidflowering vigor and frequency

Core Design Contradiction:

StrengthVSProductivity

Solution Approach 1:

The breeding program systematically varied genetic parameters through controlled crosses between parent plants with different characteristics, selecting for the specific combination of strong stem structure and vigorous flowering that defines the new cultivar

Inventive Principle:

Principle #35Parameter changes

Solution Approach 2:

The invention performs preliminary selection and stabilization of desired traits through asexual reproduction by cuttings in a controlled greenhouse environment, ensuring that the vigorous growth and long straight stem characteristics are established before commercial propagation

Inventive Principle:

Principle #10Preliminary action

2Stability of the object's composition

If existing Limonium cultivars are propagated, then reproduction is achieved, but stable inheritance of vigorous growth traits is not maintained

Engineering Contradiction:

Improvestability of vigorous growth traitsVSAvoidflowering frequency and vigor

Core Design Contradiction:

Stability of the object's compositionVSProductivity

Solution Approach 1:

The new cultivar undergoes preliminary stabilization of its genetic composition through controlled asexual reproduction by cuttings in a controlled greenhouse environment, ensuring that the vigorous growth and freely flowering traits are firmly established and will be stably inherited in successive generations

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The invention uses asexual reproduction by cuttings to create genetically identical copies of the selected plant, ensuring that the unique combination of vigorous growth and long straight stems is precisely replicated and stabilized across generations

Inventive Principle:

Principle #26Copying

3Duration of action of stationary object

If standard Limonium cultivars are grown, then commercial production is achieved, but postproduction longevity is limited

Engineering Contradiction:

Improvepostproduction longevityVSAvoidoverall commercial performance

Core Design Contradiction:

Duration of action of stationary objectVSProductivity

Solution Approach 1:

The breeding program selected for and stabilized physiological parameters that extend vase life and postproduction longevity, resulting in a cultivar that maintains commercial quality for extended periods while preserving vigorous growth and flowering characteristics

Inventive Principle:

Principle #35Parameter changes
