Hypericum Seigre Cultivar Fruit Color and Size
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current Hypericum cultivars lack unique and attractive fruit coloration, with existing varieties either having small berries in brown, red, or pink colors, failing to offer a distinct combination of large fruit size and color variation.
Innovation Solution
Development of the 'Seigre' cultivar of Hypericum androsaemum, characterized by yellow flowers, large yellow-green fruit, dark green foliage, and a vigorous upright growth habit, achieved through controlled breeding and asexual reproduction, which differs significantly from parent plants in fruit size and coloration.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If existing Hypericum cultivars are used, then they have small berries in brown, red, or pink colors, but they lack large fruit size and attractive coloration
Solution Approach 1:
The patent applies parameter changes by developing a new cultivar with fundamentally different fruit color (yellow-green) and size parameters compared to existing cultivars. The breeding program selected for large fruit size and unique yellow-green coloration, changing the physical parameters of the fruit to resolve the contradiction between fruit attractiveness and color variety.
Solution Approach 2:
The invention directly applies color changes by introducing a novel yellow-green fruit color that differs from the traditional brown, red, or pink colors of existing Hypericum cultivars. This color change creates unique and attractive fruit coloration while maintaining large fruit size, resolving the technical contradiction.
2Shape
If 'Seigre' cultivar is developed with large yellow-green fruit, then it offers unique coloration and large size, but it differs significantly from parent plants and existing cultivars requiring breeding program
Solution Approach 1:
The patent applies preliminary action by conducting a controlled breeding program before commercial propagation. The breeding program preliminarily established the desired traits of large yellow-green fruit, and only after successful development and stabilization of these traits did the patent proceed to asexual propagation for commercial production.
Solution Approach 2:
The invention applies copying by using asexual reproduction through terminal stem cuttings to replicate the unique traits of the 'Seigre' cultivar. This copying method ensures that the large yellow-green fruit characteristics are firmly fixed and retained through successive generations without requiring continuous breeding interventions.
3Stability of the object's composition
If asexual reproduction by terminal stem cuttings is used, then the cultivar reproduces true to type with fixed characteristics, but it requires controlled environment and time for root initiation
Solution Approach 1:
The patent applies self-service by allowing the terminal stem cuttings to initiate roots autonomously under controlled environmental conditions. The cutting process itself provides the necessary structures for root formation, and the controlled environment merely supports this natural rooting process without requiring additional complex interventions.
Solution Approach 2:
The invention applies parameter changes by optimizing environmental parameters (temperature, humidity, light) during the rooting phase to accelerate root initiation. By controlling these parameters, the propagation time is reduced while ensuring true-to-type reproduction and stable genetic characteristics.
