Green Gigantor Sequoia Cultivar Pollution and Disease Resistance

Solution Overview

Problem

Sequoia sempervirens plants lack robustness and resistance to atmospheric pollution and common diseases like Botrytis blight, needle blight, and redwood canker in urban landscapes.

Innovation Solution

The 'Green Gigantor' cultivar of Sequoia sempervirens exhibits improved vigor, resistance to atmospheric pollution, and enhanced resistance to Botrytis blight, needle blight, and redwood canker, characterized by an upright ascending growth habit, dense foliage, and specific botanical features.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If conventional Sequoia sempervirens plants are used in urban landscapes, then they provide basic ornamental value, but they lack robustness and resistance to atmospheric pollution

Engineering Contradiction:

ImproverobustnessVSAvoidatmospheric pollution tolerance

Core Design Contradiction:

ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The patent describes a newly discovered cultivar of Sequoia sempervirens with genetically determined parameters that differ from the species norm. The cultivar exhibits enhanced vigor, darker green foliage color, and improved resistance to atmospheric pollution and diseases through natural genetic variation rather than artificial modification.

Inventive Principle:

Principle #35Parameter changes

2Reliability

If conventional Sequoia sempervirens plants are used in urban landscapes, then they provide basic ornamental value, but they exhibit poor resistance to common diseases like Botrytis blight, needle blight, and redwood canker

Engineering Contradiction:
