Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need for a new Hippeastrum variety with excellent ornamental characteristics adapted to Israeli climatic conditions, suitable for both cut flower and pot production, that can propagate true-to-type and exhibit unique flower morphology.
Innovation Solution
The development of the interspecific hybrid Hippeastrum 'RUBY STAR' through controlled breeding, utilizing the 'twin-scaling' method for asexual propagation, which involves dividing mother bulbs into segments, treating them with BENLATE and MARPAN to prevent fungal infection, and growing in specific conditions to fix the desired characteristics.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional breeding methods are used to develop new Hippeastrum varieties, then ornamental characteristics can be improved, but the variety may not propagate true-to-type and adaptability to specific climatic conditions is limited
Solution Approach 1:
The patent applies segmentation through the twin-scaling method, dividing the mother bulb into multiple segments (typically 6-12) that are then treated and propagated separately. This segmentation allows for controlled propagation that maintains true-to-type characteristics while adapting to specific climatic conditions, resolving the contradiction between reliability and adaptability.
Solution Approach 2:
The patent employs parameter changes by modifying propagation parameters such as treatment solutions (BENLATE and MARPAN concentrations), incubation temperatures (22-24°C), and growing conditions. These controlled parameter changes enable the variety to adapt to Israeli climatic conditions while maintaining true-to-type propagation through standardized propagation protocols.
2Reliability
If the twin-scaling method is used for asexual propagation, then true-to-type propagation is achieved, but the process complexity and time required increase
Solution Approach 1:
The twin-scaling method segments the bulb into manageable pieces that can be treated and propagated systematically. This segmentation, while increasing process steps, enables true-to-type propagation by ensuring each segment receives appropriate treatment and care, making the complexity manageable through standardization.
Solution Approach 2:
The patent applies preliminary action through pre-treatment of bulb segments with BENLATE and MARPAN solutions before propagation. This preliminary treatment prevents fungal infections and prepares segments for successful propagation, reducing later problems and simplifying the overall propagation process despite the additional initial steps.
3Reliability
If bulb segments are treated with BENLATE and MARPAN, then fungal infection is prevented, but the cost of propagation materials increases
Solution Approach 1:
The patent applies preliminary anti-action by treating bulb segments with BENLATE and MARPAN solutions before propagation to prevent fungal infections. This preventive approach, while adding material costs, eliminates the need for later treatment and reduces loss from fungal infections, making the increased material cost worthwhile through improved reliability.
Solution Approach 2:
The patent uses disposable propagation materials such as vermiculite and coco-peat substrates that are inexpensive and single-use. This approach, while increasing material consumption, reduces the need for expensive reusable equipment and simplifies disposal of contaminated materials, managing costs through acceptable material turnover.
